About The Setting:
The 18K yellow gold mounting presents the large oval opal as the focal point of a versatile combination brooch and pendant design. The warm gold frame follows the elongated oval contour of the center stone, creating a clean border that emphasizes the dark body color while complementing the flashes of spectral color visible across the opal's surface. At 32.3 x 19.3mm overall, the piece has a substantial yet wearable scale, while the combination brooch and pendant construction gives it versatility as both a decorative jewelry accent and a pendant.
About The Stone:
The center stone is identified by GIA as Natural Opal in Matrix, displaying a black body color with opaque transparency and a visible play-of-color phenomenon. Its oval double-cabochon cut measures 27.00 x 15.50 x 5.45mm, providing a broad surface that allows the multicolored flashes to become the primary visual feature of the piece. GIA reports the stone as treated black, while its natural opal-in-matrix identity distinguishes it from ordinary solid-color black decorative material. The combination of the dark body tone, polished cabochon surface, and shifting play of color gives the pendant a dramatic appearance against the warm 18K yellow gold setting.
