Quartz is a staple for making jewelry. Our quartz collection includes many shades of blue and green quartz, tanzanite colored quartz, paraiba blue quartz, pink quartz, lemon quartz, amethyst, citrine, smoky quartz, and quite a few others. All are genuine gemstones, carefully harvested from our earth, some left completely natural, showing the amazing beauty of naked gems; others are given treatments to impart unique colors or looks, such as AB, diamond or mystic finishes. Quartz is a gem that lends itself well to many treatments. Gemstones have been being treated with heat and other processes for many centuries. Today, we have even more, and more precise, methods to bring out very special looks! One well-known example: London blue is one of the most popular finishes. Please enjoy our bare stones and see our incredibly beautiful marriages between nature and the most up-to-date science to give your designs superb, exquisite, unique looks!
