It is not often that we see a piece of jewelry-grade lapidary material that is so interesting and mineral-collecting relevant that we add it to the website, but this one is just visually so beautiful, I had to add it. It is a fine polished quartz with strong rutile inclusions inside, purchased in a jewelry booth at a mineral show in China (where so much of Brazilian and worldwide gem rough no goes, for carving). 25 grams. Just stunning!
