This necklace is so cool! Shiny slate black adjustable chain with a super sparkly and eye catching square blue glass gemstone. It catches the light so well that sometimes it looks dark blue, black, or baby blue. Could be dressed up or down, it's super versatile! Worn only a handful of times, original owner. No scuffs or signs of wear at all. Unclasped it's 18 inches from end to end, but can be made shorter with the adjustable hoops. Kinda goth, kinda modern, kinda classic, this seriously looks good with everything! Lia Sophia brand.
