The listing, Gold Chain & Heart Pendant has ended.
Gold Chain & Heart Pendant w/ Pearl
The chain and pendant are real gold, but I am not sure of the karat.
(FYI: It is marked "Krementz" which I looked up...Krementz is a jewelry company that specializes in costume jewelry but also makes fine jewelry. There is no karat marking on this necklace, however, after the many years I have owned this it has not flaked or tarnished, which leads me to believe it is at the very least 10 karat gold.)
The pearl that sits in the heart is genuine.
I have had this for many years and never, ever wear; I hope someone else can enjoy it!
