These are unbelievably rare to get the uvite inside or associated with Quartz!! I bought a small amount of these a few years ago and stashed them! I have not seen too many others since then. These are stellar! Meaning "all colors," tourmaline has become the most fascinating of all gem crystals. In the past 10 years, the interest in tourmaline has spiked tremendously! Many special pockets are named and pedigreed, and the sheer variety in tourmaline will always keep it popular. Look for and get to know the various color zoning, usually in the form of banding and core-coloring. Tourmaline has somewhat of a cult following. Its just one of those gems that never ceases to amaze!!
Tourmaline grows inside of Quartz in quite a few places on Earth. Most notably from the large pegmatite fields in Minas Gerais in Brazil, the Tourmaline in Quartz from there far exceeds most other deposits. Full bicolored and watermelon crystal can be found inside clear quartz, to delight a diversity of collectors!
Brazil is the one country that has the largest network of specimen and gem mining in the world. It is well known for many of the world's best pegmatites, producing high class Gem Crystals. Brazil has the widest variety of multi-colored Tourmaline worldwide, and is semi-regularly producing new colors every few years. The vast array of Quartz varieties from Brazil deserve a book of their own.
