Blue Scheelite
Blue Scheelite or Lapis Lace Onyx is a mixture of Calcite, Blue Dolomite and a little amount of Scheelite, a calcium tungstate mineral. This mixture is very rare and only found in one mine in the Kirikkale Province of Turkey, with mining having been put to a halt indefinitely.
If you're in need of good and peaceful sleep, then Blue Scheelite is the stone for you. Additionally, it heightens one's ability to be more open-minded and aligns with the Crown and Throat Chakras.
