A striking example of sculptural modernist jewelry, this dimensional converter brooch pendant combines polished black Lucite with warm 14K yellow gold and a sparkling diamond accent. Purchased from the same estate sale that I also acquired multiple Betty Cooke pieces.

The design features a substantial, smoothly polished oval of deep black Lucite, dramatically overlaid with two gently curved rectangular gold forms. The layered, offset construction creates an architectural three-dimensional effect, while the contrasting materials give the piece a bold and sophisticated presence. A prong-set round diamond rises from the black Lucite surface, adding an elegant point of brilliance to the otherwise minimalist composition.

Designed for versatility, the piece may be worn as either a brooch or a pendant, making it an exceptional statement jewel for a collector of modernist, studio, or one-of-a-kind fine jewelry. Its strong geometric lines and floating sculptural elements give it a timeless look that pairs beautifully with both contemporary and vintage wardrobes.
