Large Faceted Swiss Blue Topaz Heart Pendant 925 Sterling Silver Necklace 16"+

Sparkling, faceted Swiss blue topaz pendant on a solid sterling silver chain. Hallmarked on the back, WM, with a finesse marking of 925. I was unable to identify the maker or age of this piece. Excellent, flawless condition. The total length is 16" with a 3 inch extender. Bundle with other items from my closet for discounts and combined shipping. Questions and offers are welcome:)
