Lady's 18K White Gold White Sapphire "Drops" Necklace. Contains: 254 Round Brilliant Cut Natural Sapphires. Weight Approx: 30.00cttw, Color: White, Clarity: Transparent-LI. Necklace Length: 72 Inches. What we have here is a probably a vintage white sapphire and gold necklace, bracelet, or belly chain, depending on how you wear it. This type of jewelry was very popular during America's flapper period. This piece contains almost 300 white sapphires. They're nicely made and I think that it's a gift that would make any young lady or avant-garde woman most happy. Especially one who fancied that period. It's an awful lot of jewelry for the price.
