This is a very rare, calcium, aluminum, borate mineral species almost never seen in good crystals. A few small batches trickled out of Burma in 2007-2008 and were met with surprise and, of course, demand among rarities collectors leading to fairly high pricing at the time. The find has come and gone. I have seen in total only a few dozen specimens, all thumbnails but one, in the last 3 years. It is possible all came from the same pocket or series of small pockets, as they look identical in color and associations, making this a world class find of an extreme rarity normally relegated to the arena of "micros and reference specimens" only. These crystals, to 8 mm across, are perched on matrix and have good luster and translucence. The color is a rich, light, orangey brown. Purchased at Denver show, 2008, for $1200 from a European dealer, this is being offered (amortized) at less than the same price he paid then. It remains one of the larger and richer specimens we have seen
