Vintage Natural Ruby Solitaire Crystal Necklace in 14k

Update: took this to the jeweler on 9/22/23 and was told this is a natural ruby! The jeweler said the clear stones are diamonds, but they are too small for my diamond tester to read. Guarantee the natural ruby only. Gem: Natural Ruby Color: Light red (it's in the deep pink zone) Size: aprrx. .25ct Please see photos for more details. Setting: 14k gold On 18" chain. From a smoke-free, pet-free home!
