Here's a very pretty 10K rose gold locket pendant set with a small old-cut diamond.

This one is in excellent condition, without a ding or dent . And although my photos show yellow gold, the heart is rose gold.

It's smooth rose gold, centred with a tiny, older-cut, genuine diamond. The diamond is inset in a beautiful starburst setting. A wonderful piece dating to the Victorian era.

Locket opens at the side and there are two places for small photos, although the space behind the front does not have a metal frame or clear covering. The interior is gold metal. Locket shuts with a good snap.

Measures about 1" from the top of the jump ring by 5/8" across. Weight is 3.0 grams.

Some slight surface scratching and a tiny spot on one edge that I am confident can be polished out. The jump ring has seen better days. It's still in working order, but I would suggest replacing it.

No marks but metal tests as 10K gold.
