9 carat gold diamond and aquamarine necklace - 16. A second hand hallmarked 9 carat gold necklace. It is set with a central aquamarine drop under a solitary diamond. The necklace is a bit difficult to advise on re: length - I've underestimated as a 16 but would be a little longer.
I suspect the white gold finish could do with refreshing in the future.
