I do love hearts....This example is English, and has two substantial 15k gold bezels surrounding two perfectly cut, reflective rock crystal hearts. The locket unscrews at the top and a photo could be inserted between the crystals, if so desired.
It is in excellent condition . The bezel has initials
and a date of 1903, not visible when worn but adding charm. I search for these hearts, as the design never goes out of fashion and they are so perfect for daily wear. it measures 1 1/2 inches from the "O" ring X 1 inch across the heart.
