This is a grade AAA Larimar with beautiful patterning set in sterling silver. Larimar can only be sourced one place in the world, the Dominican Republic. Many of the mines are now underwater so it is harder and harder to find high quality Larimar. This stone carries the beauty and look of sunshine on the Caribbean Sea. The energy is calming, soothing, and allows ones true emotions to be voiced to open your heart to those around you. It comes with the heavy 15 inch chain pictured.
