Is this some kind of "trade name" for the stone? I've never heard of it. There are 2 variations of spelling on that page, but neither come up in a search.

ETA: a Search by Name on Amethyst Galleries didn't turn anything up. I sent a comment to their webmaster about where to send the URLs.

It is spelt wrong..

this is how it is spelt

TINGUAITE

Below is a link.. It is a Manmade .. and has no real holistic meanings to it..
It is a pretty rock though.. If you choose to use it I would use it in conjunction with the Heart chakra..

Had to let you in on this.. Beware of these type of advertisments..


RARE RUSSIAN GREEN STONE LANDSCAPE TINGUAITE CABOCHON

Selling for a rediculous $22 US.. Plus postage..
Its not worth it.. They are not worth overly too much probably about as much as you would pay for a small amethyst tumbled stone..

Thanks dancing bear. I will avoid the stone. I thought the name sounded lovely and now I know why. Too good to be true.
