Instructions
Examine the larimar gemstone by rubbing it with your fingers and noticing the texture. It should be smooth to the touch. Reconstituted larimar is made by crushing up scraps of larimar and low-end gemstone pieces and grinding them into a material that is combined with special epoxy and sometimes dye. This is allowed to compress and harden, and then slabbed and cut as pure larimar would be.
Look closely at the color of the gemstone using a magnifying glass. Larimar will be solid in color or have some milky white coloring mixed in. It will not have black specks or lines in the surface. If the piece you are examining does have black specks, be cautious as it might be made from the crush method as described in Step 1.
Use common sense when trying to identify genuine larimar. If a piece or product you are about to buy seems too good to be true, it probably is. Because of the difficulty in mining larimar, the price point for it is high. A reputable jeweler will be able to check a specimen to determine the authenticity.
