Vintage Yellow Gold Boulder Opal and Diamond Pendant

An elongated freeform cut opal measuring 29 x 11mm displays vivid flashes of green, blue, orange, and red in this vintage 12k yellow gold pendant. Its tapered, asymmetrical outline widens toward the base, where a triangular gold panel overlaps one corner. Pavé-set round brilliant cut diamonds totaling 0.24ctw fill this panel, contrasting with the opal’s broad, shifting bands of color. Gold prongs secure the opal around its perimeter, while an open-backed frame reveals the stone’s reverse. A separate prong-set round cut colorless stone accents the pointed top beneath a polished, tapered bail decorated with a V-shaped groove.
