Chalcedony and Sunstone Wearable Sculpture

This sculptural brooch features a dramatic carving in natural black chalcedony. The flowing form pairs elegantly polished surfaces with areas of raw stone texture, creating striking contrast and movement within the piece.

Nestled within the carving is an exceptional cabochon of Oregon sunstone, cut to reveal vivid bands of natural copper schiller. A rare natural pink diamond from the Argyle Mine adds a brilliant finishing touch. The sculpture is mounted in hand-fabricated 18k gold, allowing it to be worn either as a brooch or suspended as a pendant.

ABOUT OREGON SUNSTONE
Sunstone is a member of the feldspar family found in several locations around the world. Oregon, however, is the only locality where the gemstone’s color is created by the presence of copper within the crystal structure. This produces a distinctive range of warm hues unique to the region.

Many Oregon sunstones also display a phenomenon known as copper schiller, or aventurescence. Fine copper platelets suspended within the stone create flashes of metallic sparkle that seem to shimmer within the gem when it moves in the light.
