This is a first-rate Titanite twin, probably from the newer finds in the Koksha Valley. The crystal is remarkably gemmy and bright, with the twinning plane very well-defined. One of the best Titanites that I have seen from this area, it displays beautifully from the side or right down the twinning plane. Even better in person.
