Larimar gemstone also known as the Dolphin Stone only found in the Dominican Republic is largely sought after for its beautiful blue and white patterns resembling the Caribbean ocean. I purchased a large lot of Larimar directly from the Dominican Republic for resale in art shows before Covid struck. My loss is your gain at these greatly reduced prices. All Larimar products are new but have no tags or packaging since they came from an individual wholesaler in the DR. This listing is for stone I shown in the group photo for size comparison. The stone size is 23mm x 17mm x 9mm (approximately 3/4" x .5" teardrop) and set in Sterling Silver. The chain is Sterling Silver, 1.2mm box, anti-tarnish coating, adjustable from 16 to 24 inches with a lobster claw clasp.
