All sea glass is genuine SEA GLASS I find all my own sea glass in Puerto Rico This sea glass is NOT altered or tumbled in anyway, it is only tumbled naturally by the ocean. Choose your sea glass color: Kelly green Light aqua Choose your string color: Tan Chestnut these bracelets are made to order, so you may not get the exact one in the photos. However, I try my best to make them as accurately as I can to the photos. These are natural materials so no bracelet will be exactly the same.
