Chunky 10mm snow cap faceted black Agate with a gorgeous faceted black Onyx double horn dangle! These yoga bracelets are stunning! I fell in love with the stones as soon as I saw them, and when I found the dangles, I knew I had to make these beauties! Black Agate and Black Onyx are grounding and protective crystals. They give a calming peace that helps those during a period of bereavement. They give inner strength to move on and move forward. The mixture of the white Agate with the black promotes balance and release.
