D'Orlan Heart Pendant on 15" Gold Tone Chain with Crystals

D'Orlan Heart Pendant on 15" Gold Tone Chain with Crystals - they could be Swarovski as D'Orlan did use Swarovski in their pieces. Chain also marked D'Orlan. Such a cute piece! The heart is 3/4" x 5/8" and is also marked 5506 on the back. Lovely condition.
