Vintage 18K Gold/Platinum Chunky Blue Topaz Diamond Drop Pendant Necklace

A pentagon-cut blue topaz anchors this 18-karat white gold and diamond drop pendant necklace, hung on a platinum box chain. Two slender diamond strands fall from the lower point of the stone at staggered lengths, and each ends in a pear-shaped diamond. Topaz rates 8 on the Mohs hardness scale, hard enough to keep its facet edges sharp with regular wear. The chain passes through a concealed bail behind the setting. This keeps the topaz flat and centered while the strands swing with each step, making it a focal piece for an open neckline.
