This is such a sparkling heart pendant. No worries about the gold wearing off. After 35 years, it is as beautiful as the day I purchased it in downtown, L.a. One side has 2 love birds/humming birds? They are facing each other inside another sparkling diamond cut heart. The outside border has the nicest filigree design, as is the entire back of the pendant. t is 1 1/2 inch wide and long, including the bail. I don't know which side I like more. You can wear it on either side. The 18 inch snake chain is also gold over sterling silver. Hallmarks on the bail and the clasp of the chain. SS Italy. 3.8grams No sign of wear at all. Perfect condition. This is the prettiest gold heart I've ever seen, and I've seen a lot of gold hearts!
