Who knows about Optical Calcite?

This is not ordinary "calcite"; this is a rhomboid crystal full of rainbows all over... it is a particularly beautiful stone, very unfortunately far too soft & brittle for using in jewelry - which usually it's too big for at any rate. Does anyone here know its qualities? I find it a particularly soothing stone, & is my #1 fave crystal which I always have on my altar surface.

Calcite - Optical

Optical calcite is useful in working gemstone magick, as it doubles the strength and power of your spell. It is also useful in cleansing the aura, clearing all attachments and entities. Allows you to see the spiritual more readily

Yes, I think I have gotten those things out of my OC, & I will get even more out of it now - thanx!
