Rare Authentic Natural Large Rectangle Rainbow Spectrolite Cabochon with Rare Silver Flash

Natural Authentic Large Rectangle Rainbow Spectrolite Cabochon
Material from Finland, the only place on earth you can get authentic Spectrolite. (You can trust me on this. Some will try to sell highly colorful Labradorite as Spectrolite. Ask them where the material is from.)
Great polish all around with lower dome, rounded edge flat sides (girdles) and polished flat back. Super flash!
Size: 60.2 x 49.8 x 7mm This is a substantial stone, not thin.
Very collectible deep twinning (where the crystals slip and form natural lines in the material) and bright color on both sides (see video)
Ships in bag in bubble wrap (a lot) in bubble mailer. Can be put in box. PM me.
Sorry, no International sales except to Canada. Unless you want to pay the high shipping....
