Silver Stack Ring: Pink or Green Tourmaline .925 Silver Playing with positive space. Like roots in nature! Stack it with another ring, rotate it on your finger, every day you will see something new. How does Tourmaline grow? Tourmaline deposits are usually found in Granite or Metamorphic rocks. Rocks that are subjected to pressure or heat and begin to change. A little space deep underground in this changing rock may fill with a hot liquid/gas that is rich in different minerals. When the liquid begins to cool it may form a tourmaline crystal. It just blows me away! I mean nature is the real artist here! Your Silver Stack ring is made in Kaernten, Austria using 100% recycled gold, a steady hand and alot of joy. #PS-R1BR How can I check my ring size? Do you already have an existing ring that fits?
