Gorgeous one-of-a-kind 14K Gold necklace?the Omega marked chain choker looks solid, but it's flexible and marked 14K. I THINK it would be called a herringbone, but you cannot see that unless it is flexed. It's very hard to see, but a jeweler also confirmed it to be a solid 14K. It is unique, and I have never seen a clasp like this one. The previous owner told me it was bought in Barbados in one of the expensive jewelry shops there. The prong-set amethyst stone?the jeweler said the stone was an authentic natural amethyst?Trillion cut-and the six diamonds?6 points each?are real. It is a stunning set, and the diamonds can be worn separately. Total gram weight is: 27.5 The pendant is 3/4" wide and 5/8" long. Choker is 16.5" 1/8" wide
