Until I found this specimen I was under the impression that Kyanite only came in blue but alas, here it is in black!  I love this necklace...it reminds me of the Game of Thrones' "throne".  Here I took this character-rich stone and coated it with solder to attach onto a thick, silver rope chain.  I have multiple pieces with the black kyanite which are all different, so just be wary that you may receive a piece a little different from the one pictured.
