10k Gold Heart Pendant with single Diamond

The chain for this broke, and I never bothered to buy a new one! So, it’s just the pendant for sale. I think it was from Peoples Jewellers if I’m remembering properly. It’s 10 karat gold as per the markings, and has a single small diamond at the bottom. As can been seen in the photos, the back side is “hollow,” which makes this pendant very lightweight and delicate. See photos for measurement of pendant. It’s just about 1/2”. Very simple and elegant.
