This is a very pretty heart pendant. There is a natural heart shaped Amethyst stone set in 14K white gold. No hallmarks, but the gold was acid tested. Above the Amethyst are 2 Moonstones, and small Diamonds. The top of the piece has a small flower design made of one center Moonstone, and 8 small Diamonds. Below that there is a larger Moonstone with 2 leaves, each leaf also has a small Diamond. The Moonstones have a pretty bluish tint. The pendant has lots of movement, which gives beautiful color and sparkle to the piece. The total length is about 1 1/2". The Amethyst measures 14mm X 16mm. Condition is very good with no damage that I can see with a 10X loupe. Very minor flea bite to the Amethyst. Weight is 4.0 grms. I would date this fine pendant at c1990's.
