This is a large triangular 14K yellow gold pendant set with a single small diamond, and suspended from a substantial 22 inch long 18K yellow gold necklace chain. The total weight of both is 8.9 gr. The pendant is marked 14K on the back. The chain tests positive for gold content of 18K. The chain is marked on the clasp end with what I think may be a patent number for the clasp, but I was not able to get a clear photo.
The pendant measures 1.5" between the 2 open points and 1.5" along the sides. The diamond is small, measuring about 1.5mm across.
Condition is good.
The pendant resembles a variation of a Star Trek insignia, but I think this resemblance is coincidental.
