Ca2[B(OH)4](AsO4) / Tetragonal - Disphenoidal (very rare structure)
This crystal has the most unique frequencies of all the crystals I have tested, however it is a very rare crystal. This unique crystal will lift you up into a warm ocean of emptiness and light. It is so unique in energies that I have placed it in the top of the top 200 as nothing comes close to Cahnite - maybe not the highest in frequencies and not the most powerful but certainly the most unique out of all the crystals in the world.
In honor of Mr. Lazard Cahn, an American morphological crystallographer, mineral collector and mineral dealer, who first recognized this material.
It is too bad it is such a rare crystal as this one beats the phenacite and is just under penfieldite and kamphaugite.x
