Estate 18KT Yellow Gold Synthetic Emerald and Diamond Brutalist Pendant, ca. 1970’s (As-Is)

Crafted in 18kt yellow gold, this Brutalist pendant from the 1970’s centers on a rough synthetic emerald crystal cluster measuring 26 x 16mm, cradled in a freeform gold setting. A round brilliant cut diamond of approximately 0.15 carats, H-I color and VS2 clarity, sits in a raised prong setting at one side, balanced by a sculpted gold accent at the other. The pendant measures 1 3/8 inches long by 3/4 inch wide, weighs 12.9 grams, and is stamped 18K and signed “S.L.” No chain included.

Synthetic emerald is grown in a laboratory and shares the same chemical composition and crystal structure as natural emerald, giving it the same rich green color. Left uncut, the crystals here keep their natural hexagonal forms, stacked and clustered like a mineral specimen. Brutalist jewelry favors raw, sculptural shapes and organic metalwork over polished symmetry, and this pendant leans fully into that approach, with the gold framing the cluster rather than containing it.

Please note, this piece is sold as-is: some crystals are stabilized with epoxy.

A bold choice for collectors of 1970’s Brutalist design, this pendant brings together raw crystal, sculpted gold, and a bright diamond accent in one wearable piece of art. It would also make a memorable gift for anyone who loves unconventional jewelry with real character.
