Topaz Of The World Crystal T-Shirt by Angry Turtle

Topaz Of The World Crystal T-Shirt by Angry TurtlePreviously offered only in person at gem shows, this shirt shows fine crystals of topaz from around the world! Though we are best known for our fine lab created crystals I am a bit of a topaz maniac and I've collected interesting examples from a variety of locales, ranging from classics like Brazil to exotics from Germany and Zambia. Beautiful printing done locally in our town! Stay tuned for more shirts!

These are BGO-12 aka Bismuth Germanate facet rough

These are the two grits included in the kit

Light passing through TGG in the presence of a magnetic field has its polarization rotated

CFL (strawberry pink)

nice for me because I really need to clear them out

We have complete pixel prisms

These pieces are off the ends of boules

It weighs in at 3

The crystal was apparently grown for use in lasers

It's also a little tenebrescent--exposure to UV intensifies the color while allowing it to sit in the dark for a while returns it to its original intensity

This includes both an ER-11 1/4" collet and a collet nut so it can be easily swapped back and fourth with the 6mm collet that comes with the handpiece

Perovskite is a really unusual laser crystal
