Opals are highly valued as a gemstone and a healing stone. They have a beautiful, soft rainbow, luminescent quality to them. However, because opals do not have a crystalline structure, they are technically not regarded as crystals. Opals are soft with a high water content, which makes them particularly delicate. They can be colorless, white, and yellow, violet, red, pink, orange, green, blue, and black. Root chakra is related to red or black opals, sacral relates to orange, solar plexus on yellow, the heart chakra on green or pink, throat on blue, violet the third eye, the crown and higher chakras on colorless or white. You should never clean an opal in water or with chemicals, including opal jewelry pieces. They are natural, tumbled and polished, or cut. They have amplifying energy qualities so they will help increase the power of other crystals. They help with creativity, dreams, connection to the Divine and higher self, facilitating the flow of transformation, assisting in moving easily through obstacles, improving memory and inspiration. You can place opals near the head of your bed for meditation and dreaming, on or near any chakra, and as a jewelry of any type. It is considered good luck to receive an opal piece of jewelry from someone else. Opal is very popular in jewelry. It is important to store opals carefully, away from other crystals to prevent damage as they are so soft.
