Comment: These extremely distinctive uvites were found last year in Pakistan, and several things make them interesting. First, they are isolated on this chalky, intensely white talc matrix (unusual!), so they really pop out visually. But they also have a very unique deep sherry color - and are gemmy! The crystals on this specimen measure up to one centimeter.
