Vintage Deb Guyot 925 Nigerian amethyst modernist collar necklace

Stunning! Measures 21” around and weighs about 120 grams. All sterling with Nigerian amethyst pieces. It is signed on the hook and marked ‘925.’ These do not show up in the photos because I have not polished the item, but you can do so if you wish. Mint condition. Really a stunning piece! Estate item from Del Mar, CA.
