Raw Angelite

Oh, angelite, you are so sweet! One of the first gems I ever worked with when I was just a teenager beginning my spiritual journey. I adore it, and I think once you learn about its powers, you will too. Angelite acts as an anchor to our angelic guides; it channels clear communication lines to them. It also helps you speak freely and from a place of tranquility. How fitting to have this stone carved into these perfect pocket angel statuettes.
