Here is a super seven crystal with part of the crystal polished to show the mineral layers inside the crystal.
I purchased these crystals in Govenador Valadares, Minas Gerais, Brazil, from miners who traveled there to sell their crystals.
When I saw these crystals, I knew they had to be polished. The mineral and amethyst layers inside the crystal are heavily saturated and from the top of the crystal you might just think its a smokey.
However, when you polish the crystal from the bottom up, you can see the internal layering, its like rings of a tree in some crystals.
The termination of the crystal has been left natural.
This crystal is 6.5 x 4 x 2 cm.
