Opal

Opal is the October birthstone. Flashes of color dancing in a glimmering stone, there’s not much that needs to be said about its beauty. This gemstone is as versatile as it is colorful – use it for playfulness and strength, tenderness and truth, to amplify your karma and keep your cool all at once.

Opal absorbs and reflects light as it dances, and likewise, it picks up thoughts and feelings, desires and buried emotions, amplifying them and returning them to the source. Opal helps you to let go of patterns of fear, anger, negativity and self-harm. If you need to let go of the one who doesn’t deserve you, have faith in Opal and this too shall pass.

With a hardness of 5.5 to 6.5 on the Mohs scale, opal is a softer gemstone. This means that opal can easily be scratched, even by dust particles. High heat and sudden temperature changes can cause opal to crack. Because opals are porous you should avoid contact with chemicals, cosmetics and household cleaners while wearing your opal. Don’t wear your opal jewelry during physical activity, like sports or gardening. The only safe way to clean opal is with warm, soapy water.
