I bought this lovely sphere as rainbow obsidian, as you can see in the pictures it has wonderful shimmering green/grey on it's ends but not many rainbow colours as such so I am just calling it obsidian (with hidden magic extras). It is a very lovely sphere that feels really grounding and clear to hold. It measures about 8.5cm across.
In crystal healing Black Obsidian is seen as providing an instant connection to the Root Chakra, it is a deeply grounding and protecting stone, defending the carrier from psychic attack.
It is also known as the “grief stone” as it is thought to be very helpful for those dealing with the loss of a loved one. If it is held during meditation it can unblock hidden feelings of grief allowing the healing process to start.Read more about the healing properties for Black Obsidian
