Art Deco Onyx and Diamond Necklace

A stunning example of Onyx and Diamond Art Deco jewelry! Crafted in platinum circa 1910, this pendant features an Old Mine Cut Diamond at its center surrounded by uniquely shaped carved black onyx.  Two Antique Pear Cut Diamonds, weighing approximately 0.90 carats together are at the top and bottom of the pendant.  An additional 0.75 carats of Old Cut diamond accents frame the onyx, all with the period-perfect milgrain that we love.  Combined, this pendant has 1.82 total carat weight of sparkling antique diamonds.  The contrast of the bright white diamonds and platinum alongside the deep black of the onyx would add a sophisticated glamour to any look!
