Vintage 10.74 Carat Boulder Opal and Diamond Pendant Necklace

A fabulous vintage heirloom, this vivacious boulder opal pendant necklace is a statement of natural beauty. This impressive 10.74 carat gemstone is carved in a freeform, following the contours of the rough gem and showcased in yellow gold, platinum and diamonds that enhance the shape.
Fireworks. Galaxies. Lightning. Opal’s shifting play of kaleidoscopic colors is unlike any other gem. Microscopic arrays of stacked spheres diffract light into a blaze of flashing colors.
