Larimar cabochons weighing 12.3 carats total weight and measuring approximately 15x12mm set in Sterling silver simple four prong settings and Fine silver earring wires. These genuine, pear shaped gemstones are only found in one place in the world, the Dominican Republic, where they initially were discovered on the beach, since then they are discovered in the rivers leading down to the ocean. I do have other earring wires and posts that can be used with these settings, this is the least expensive option at this time, message me for options.
