Three slabs of natural crystal, each cut by hand, sit one above another in a slender brass frame. Lit together, they carry a column of warm light up the wall, giving this sconce a vertical presence that a single stone could not.Because every slab is shaped by hand, no two stones match, even on the same fixture. At 31.3 inches tall, it reads best where there is height to fill: a stair wall, a double-height entry, a long hallway or a tall bedroom wall. It works on its own or mirrored as a pair, and can sit beside a vanity in a dry, protected spot.Details Dimensions: 79.4 cm (31.3 in) H x 15.2 cm (6 in) W x 14 cm (5.5 in) D Projection from wall: 14 cm (5.5 in) Materials: three hand-cut natural crystal slabs in a brass frame Finishes: brass, silver or black Bulbs: E12 sockets in North America, E14 in other markets; 2700K warm white recommended Weight: approximately 7 to 9 kg Installation: hardwired to a wall junction box; because of its weight, fix into structure or a rated box with reinforced mounting Use: dry indoor locations only

A solid copper stem rises to hold a drum of faceted crystal in this compact table lamp. Each prism is cut by hand on its own, so the way the light scatters differs slightly from one lamp to the next. Switched off, the crystal still picks up daylight and lamplight from around the room.Set it on a desk and the broken light spreads across the work surface, or place it beside the bed to cast a soft glow on the wall behind. The lamp has real weight to it, which keeps it steady on polished furniture. A matching 160 cm floor lamp is also available.Details Materials: solid copper stem, faceted crystal drum Height: 60 cm (23.6 in) Width: 35 cm (13.8 in) Light: warm white, 2700K, chosen to keep the copper looking warm Voltage: 110 to 240V, configured for your region

A slender copper column rises to a drum of faceted crystal glass, where the light gathers and breaks into soft points of brilliance. The deep tone of the metal keeps the lower half quiet and grounded, so the eye travels upward to the glowing crown.The lamp has a strong Art Deco character. It sits comfortably beside a reading chair or at the corner of a bedroom, and it holds its own in a dining room or a hotel lobby that calls for a bit of drama.Details Dimensions: 17.7 in diameter × 63 in high (Ø45 × H160 cm) Materials: Copper with faceted glass crystal Weight: Approximately 18 to 24 kg Bulb base: E12/E14

This round pendant is built from faceted amber crystal set around a solid copper core, forming a full sphere that glows a rich, honeyed color when lit. The cut surfaces scatter the light softly, so the fixture reads as warm and substantial without throwing hard glare into the room.The smaller size suits a bedside or side table on its own, and it also works well hung in pairs or a short row above a kitchen island or dining table. The larger size carries a foyer, stairwell or dining room by itself. Over a table, plan for the bottom of the sphere to sit roughly 75 to 90 cm (30 to 35") above the surface.Details Materials: Amber K9 optical crystal around a solid copper core Sizes: Small, 32 cm (12.6") diameter; Large, 64 cm (25.2") diameter Suspension: 100 cm (39.4") cable, length set during installation Approximate weight: Small 6 to 9 kg (13 to 20 lb); Large 14 to 20 kg (31 to 44 lb) Lamping: E14 sockets (E12 for North America), warm white 2700K recommended Installation: Given the weight, an electrician should verify that the ceiling junction box can support the fixture

A slim column of clear K9 crystal hangs from a solid copper frame, its many cut facets catching the light and scattering it into a crisp, silvery shimmer. At just 14 cm (5.5") across, it brings a lot of sparkle without taking up much room.The smaller version sits comfortably beside a bed or in a powder room, and works well in a line of two to four above a kitchen island. The taller version suits stairwells, double-height entries and long corridors, hung singly or clustered at varied heights. Over a counter, plan for the bottom of the fixture to sit 75 to 90 cm (30 to 35") above the surface.Details Materials: clear K9 crystal on a solid copper structure Small: 14 cm (5.5") wide, 53 cm (20.9") tall, approx. 4 to 6 kg (9 to 13 lb) Large: 14 cm (5.5") wide, 90 cm (35.4") tall, approx. 7 to 10 kg (15 to 22 lb) Bulb type: E14 (E12 for North America), warm white 2700K recommended Also offered in amber crystal

A slim column of amber K9 crystal wrapped around a solid copper frame, this pendant glows with a warm, honey-colored light. Hundreds of cut crystals catch and scatter the light, so the fixture reads as rich and luminous even at low output.The smaller size works well beside a bed, in a powder room, or hung in a line of two to four over a kitchen island. The larger size suits stairwells, double-height entries and corridors, on its own or clustered at varied heights. Over a counter, plan for the base to sit 75 to 90 cm (30 to 35 in) above the surface.Details Materials: Amber K9 crystal on a solid copper structure Width: 14 cm (5.5 in) Height: Small 53 cm (20.9 in); Large 90 cm (35.4 in) Approximate weight: Small 4 to 6 kg (9 to 13 lb); Large 7 to 10 kg (15 to 22 lb) Light source: E14 sockets (E12 for North America), warm white 2700K bulbs recommended Also available: Clear crystal version and a round globe pendant

A slim, tapered rod of brushed stainless steel rises from the wall and ends in a lit crystal tip. The glow begins at the crystal and runs down the length of the metal, so the sconce reads on the wall as one clean vertical line.The brushed finish catches soft shadow along the rod instead of throwing back a flat shine, and the cut crystal scatters light where it meets the steel. At 50 cm it is slender but has real presence. It works well in a hallway, at an entry, along a staircase or in a niche. Mounted as a pair on either side of a doorway, it makes the most of that vertical form.Details Materials: Brushed stainless steel with a cut crystal tip Dimensions: 50 cm H x 11 cm W x 11 cm D (19.7 x 4.3 x 4.3 in) Weight: Approximately 1.8 to 2.5 kg Light source: G9 bulb, warm white 2700K Installation: Hardwired wall mount

A slender column of faceted K9 crystal in a smoky amber shade, this sconce scatters light into fine glints across the wall. The tint adds warmth of its own, so the glow reads like honey when paired with warm white bulbs.The shorter 53 cm version sits comfortably beside a bed, in a powder room or as a pair flanking a mirror. The 90 cm version carries the eye upward along a stairwell, a long hallway or a tall entrance.Details Material: Hand-cut K9 crystal Color: Smoked amber Width: 20 cm (7.9") Heights: 53 cm (20.9") or 90 cm (35.4") Weight: About 3.5 kg (8 lb) at 53 cm, about 5.2 kg (11 lb) at 90 cm Bulb type: E14 sockets (E12 for North America) Recommended bulbs: Warm white, 2700K Installation: Hardwired Use: Indoor

A wide, shallow ring of faceted K9 crystal beads in smoked amber, packed tightly along a slender brass frame so the whole circle reads as one unbroken band of light. The tinted glass brings warmth and depth, and it pairs naturally with walnut, bronze, leather and darker painted walls.An integrated LED tucked inside the ring lights the crystal from within, spreading an even glow around the full circumference. The effect is ambient and sparkling rather than a focused downlight, so a dining table used for work or reading will benefit from additional task lighting nearby. The 2700K warm white is essential to the look: under it the amber turns a rich honey color, where cooler light would make it appear flat and brown.The smaller rings suit a compact entry or a round table roughly 90 to 160 cm (35 to 63") across. The middle sizes fit a typical foyer, living room or generous dining table, and the two largest are scaled for grand entrances and double-height rooms. Above a table, aim for the lower edge to sit 75 to 90 cm (30 to 35") over the surface. Even at full size, the ring keeps a low profile.Details Materials: smoked amber K9 crystal beads, brass frame Color: Amber 60 cm: 60 cm (23.6") diameter x 12 cm (4.7") high; 9 light sources; approx. 12 to 15 kg (26 to 33 lb) 80 cm: 80 cm (31.5") x 16 cm (6.3"); 12 light sources; approx. 18 to 24 kg (40 to 53 lb) 100 cm: 100 cm (39.4") x 18 cm (7.1"); 16 light sources; approx. 26 to 34 kg (57 to 75 lb) 120 cm: 120 cm (47.2") x 20 cm (7.9"); 18 light sources; approx. 35 to 45 kg (77 to 99 lb) 150 cm: 150 cm (59.1") x 20 cm (7.9"); 25 light sources; approx. 48 to 60 kg (106 to 132 lb) 180 cm: 180 cm (70.9") x 22 cm (8.7"); 30 light sources; approx. 62 to 78 kg (137 to 172 lb) Light source: integrated LED, 2700K warm white Suspension: adjustable fine wires, 1.5 m (4.9 ft); longer wires possible for tall ceilings Installation: hardwired; must be secured by an electrician to a joist or reinforced blocking, with structural support planned for larger sizes CareTurn the power off before cleaning. For routine upkeep, go over the crystal with a feather duster or soft dry cloth. When the beads need more attention, use a lightly dampened microfiber cloth and dry each one right away. Wipe the brass with a dry cloth only and skip any polish.

A slender column of hand-cut clear crystal rises along a polished silver frame, catching light in every facet and scattering it as fine, bright points across the metal and the wall behind. The effect is crisp and luminous, with a warm cast from the recommended lamping.The shorter 53 cm height sits comfortably beside a bed, in a powder room, or as a matched pair flanking a mirror. The 90 cm version has the presence to hold a stairwell, a long hallway or a tall entrance.Details Materials: Hand-cut clear crystal on a silver frame Width: 20 cm (7.9") Heights: 53 cm (20.9") or 90 cm (35.4") Bulb type: E14 (E12 for North America) Recommended lamping: Warm white, 2700K Installation: Hardwired wall mount Also offered: The same design in smoked amber crystal

A shallow ring of closely packed K9 crystal beads sits on a slender iron frame finished in silver. Integrated LED light travels around the full circle and passes out through the crystal, so the ring reads as one unbroken band of sparkle while glare stays low. Fine wires carry the fixture, which gives it the look of hovering in the room.Crystal picks up the color of the light behind it. In warm white at 2700K the beads take on a soft champagne glow, which is how this design is meant to be seen. Cool white is offered for rooms already lit in a crisper tone. Because the profile is so slim, views across the room stay open, and the smaller sizes suit compact entries, bedrooms and round tables of roughly 110 to 150 cm (43 to 59"). The middle sizes work in typical foyers, living rooms and over dining tables of about 180 to 240 cm (71 to 94"), and the two largest are scaled for grand entries, double-height spaces and hotel rooms. Above a table, aim for 75 to 90 cm (30 to 35") between the tabletop and the underside of the ring. Over a kitchen island or work surface, plan on separate task lighting too.Details Materials: K9 crystal beads, iron frame with silver finish Ceiling rose: silver or gold Light source: integrated LED, no replaceable bulbs Light color: warm white 2700K or cool white 60 cm: 60 cm (23.6") wide, 12 cm (4.7") high, 9 light sources, about 2,000 lumens, 12 to 15 kg (26 to 33 lb) 80 cm: 80 cm (31.5") wide, 16 cm (6.3") high, 12 light sources, 18 to 24 kg (40 to 53 lb) 100 cm: 100 cm (39.4") wide, 18 cm (7.1") high, 16 light sources, 26 to 34 kg (57 to 75 lb) 120 cm: 120 cm (47.2") wide, 20 cm (7.9") high, 18 light sources, 35 to 45 kg (77 to 99 lb) 150 cm: 150 cm (59.1") wide, 20 cm (7.9") high, 25 light sources, 48 to 60 kg (106 to 132 lb) 180 cm: 180 cm (70.9") wide, 22 cm (8.7") high, 30 light sources, about 9,000 lumens, 62 to 78 kg (137 to 172 lb) Suspension: 1.5 m (4.9 ft) of fine wire, set to height during installation; longer or shorter lengths available Installation: hardwired; an electrician should secure it to a joist or reinforced blocking and check that the ceiling can support the weight of larger sizes CareTurn the power off before cleaning. Routine dusting needs only a feather duster or soft dry cloth. For a fuller clean, dampen a microfiber cloth with a small amount of mild glass cleaner and wipe the beads by hand, keeping any spray away from the fixture itself. Avoid abrasive cleaners on the silver finish.

A shallow round drum of crystal panels, this chandelier reads as a bright ring of light rather than a heavy fixture. Every panel is individually cut and polished, so the crystal catches light with real depth and small natural variations from piece to piece.At just 21 cm tall, it sits comfortably under ceilings of roughly 2.4 m (8 ft). The two smaller diameters work well in a bedroom, an entry or above a compact round table. The 80 cm size is scaled for a dining table seating six to eight, and the 100 cm suits a generous dining room, living room or foyer. When hung over a table, aim for 75 to 90 cm (30 to 35") between the tabletop and the bottom of the ring.Details Construction: cut and polished crystal panels in a round frame Finish: gold (brass) or black (stainless steel) Diameter: 50 cm (19.7"), 60 cm (23.6"), 80 cm (31.5") or 100 cm (39.4") Height: 21 cm (8.3") Suspension: 50 cm (19.7") chain as standard, with longer lengths available Bulb type: E14 sockets (E12 for North America) Recommended light: warm white, 2700K Options: sloped ceiling adapter and dimming available

A slender black frame curves up and over a clear glass bell, holding the shade in suspension above the surface. Inside the bell sits a second glass cylinder, and a small crystal detail hangs at the center, catching light when the lamp is on.The two layers of glass gently diffuse the glow while keeping the bulb visible, so a warm filament bulb suits it well. Because each bell is shaped by hand, you may notice slight differences in glass thickness and small internal marks from one lamp to the next. It sits comfortably on a nightstand, a living room side table or an entry console.Details Frame finish: Black (also offered in brass) Shade: Clear hand-formed glass bell with inner glass cylinder and suspended crystal detail Dimensions: 24 cm (9.4") diameter, 45 cm (17.7") high Light: Warm white, 2700K

Tiers of crystal rings descend from a slim metal frame in this low-profile ceiling light, catching the light and scattering a soft shimmer over the fixture and the ceiling around it. Because it sits close to the ceiling, it works well in rooms where a hanging chandelier would take up too much headroom.The integrated LED offers warm, natural and cool white settings. We recommend the warm 2700K setting, which gives the crystal a gentle golden glow. Cooler settings make the sparkle crisper and more blue-white. The light spreads in all directions for bright general illumination, so plan on separate task lighting over a desk or vanity.Details Materials: Crystal rings on a slim metal frame Finishes: Gold or silver (chrome) Diameters: 40 cm (15.7 in), 50 cm (19.7 in), 60 cm (23.6 in) Room sizing: 40 cm for rooms up to about 10 x 10 ft; 50 cm for rooms around 12 x 13 ft; 60 cm for rooms around 13 x 16 ft Light source: Integrated LED with warm (2700K), natural and cool white settings Installation: Hardwired, mounts directly to the ceiling CareTurn the fixture off and allow it to cool before cleaning. Dust the crystal with a soft dry cloth or feather duster. For a deeper clean, apply a small amount of mild glass cleaner to a damp microfiber cloth and wipe the crystal, never spraying the fixture directly. Avoid abrasive products on the frame.

Faceted crystal is set around a sculpted resin body in this compact wall sconce. As the light passes through, the crystal scatters it into fine points of sparkle, while the resin gives the fixture a solid, grounded shape.At 6 inches wide and 12 inches high, it brings the glint of crystal to places where a larger fixture would overwhelm, such as beside a bed, along a hallway, on a dining room wall or in a powder room. It looks especially good mounted in pairs.Details Materials: Faceted crystal and sculpted resin Dimensions: 15.2 cm (6") W x 30.5 cm (12") H Light source: Integrated LED, warm white 2700K Weight: Approximately 1.5 to 2.5 kg (3 to 6 lb) Installation: Hardwired; mounts to a standard wall box Placement: Can be used beside a vanity in a dry, protected spot away from direct water

This sconce is a single long rod of tapered brass finished with a glowing crystal tip. Light gathers at the crystal and runs along the metal in both directions, so on the wall it reads as one clean vertical stroke. The brass is worked to catch shadow down its length instead of reflecting flatly, and the crystal is cut to scatter light where it meets the rod.At 92 cm tall with a projection of only 7 cm, it adds height to a wall while staying close to it. That makes it a natural fit for hallways, stair walls, entrances and niches. In a living room or bedroom, a pair works well framing a doorway, a mirror or a headboard.Details Materials: Brass and crystal Dimensions: 92 cm H x 11 cm W x 7 cm D (36.2 x 4.3 x 2.8 in) Weight: Approximately 2 to 2.5 kg Light source: G9 bulb, warm white 2700K Installation: Hardwired wall mount

This floor lamp rises as a slender column of cut K9 crystal rods, each one catching the light and breaking it into small flashes of color. The rods sit on a solid copper column and a weighted base finished in gold, so the lamp reads as a tall, glowing vertical line in a foyer, a formal living room corner or beside a bed.Ten light points shine through the crystal. The effect is a bright, sparkling decorative glow rather than a focused reading light. K9 crystal is prized for its clarity and high refractive index, which gives it far more brilliance than ordinary glass. At about 22 kg, the lamp is heavy and stable, so it is best placed once and then styled around.Details Dimensions: H 170 cm x Ø 30 cm (approx. 67 in x 12 in) Materials: K9 crystal rods, solid copper column and weighted base Color: amber Light source: 10 x E12/E14 sockets, LED compatible Color temperature: 2700K warm white by default Dimming: standard version is not dimmable; a dimmable version can be requested Voltage: 110V or 240V, configured for your region Installation: plug-in with in-line switch Weight: approx. 22 kg Use: dry indoor locations only

Hundreds of K9 crystal rods fall in concentric tiers from a solid brass frame, creating a layered column of glass that catches the light from the lamps above and scatters it into a field of small, bright points below. The effect is architectural, more like a sculpted volume of light than an ornament.Three diameters cover a wide range of rooms. The smallest sits comfortably over a round table seating eight to ten where the ceiling reaches roughly 2.7 m (9 ft). The middle size suits a table for ten to fourteen or a generous living room, and the largest is scaled for grand dining rooms, double-height entries and hotel lobbies. When hanging it over a table, aim for 80 to 90 cm (32 to 35") between the tabletop and the bottom tier.Details Materials: K9 crystal rods on a solid brass frame Frame finish: Gold (brass) or Black (black stainless steel) Sizes: 91 cm (36") diameter, 95 cm (37.4") high; 122 cm (48") diameter, 114 cm (44.9") high; 152 cm (60") diameter, 164 cm (64.6") high Approximate weight: 16 to 22 kg (35 to 49 lb), 26 to 34 kg (57 to 75 lb) or 40 to 52 kg (88 to 115 lb), depending on size Suspension: 50 cm (19.7") rod, with extra 20 cm and 30 cm extension sections included Lamping: E27 sockets (E26 for North America), warm white 2700K recommended Options: Sloped ceiling adapter and dimming available Installation: Because of its weight, each size must be secured to a structural ceiling point by a qualified electrician

Hundreds of hand-cut K9 crystal rods hang in concentric tiers from a slim stainless steel frame, catching the light from the lamps above and scattering it into a field of small, bright points below. The effect is architectural and quietly dramatic, with the crystal doing most of the work.Three diameters let you scale the piece to the room. The 91 cm size sits well over a round table for eight to ten under ceilings of roughly 2.7 m (9 ft). The 122 cm size suits a table for ten to fourteen or a generous living room. The 152 cm size is meant for grand dining rooms, double-height entries and hotel lobbies. Over a table, plan for the lowest tier to sit 80 to 90 cm (32 to 35") above the surface.Details Materials: Hand-cut K9 crystal rods on a stainless steel frame Frame finish: Black or gold (brass) 91 cm (36") diameter: 95 cm (37.4") high, approx. 16 to 22 kg (35 to 49 lb) 122 cm (48") diameter: 114 cm (44.9") high, approx. 26 to 34 kg (57 to 75 lb) 152 cm (60") diameter: 164 cm (64.6") high, approx. 40 to 52 kg (88 to 115 lb) Lamping: E27 sockets (E26 for North America), designed for warm white 2700K lamps Installation: All sizes require a structural ceiling fixing installed by a qualified electrician
