What is Moss Opal?
Like all opals, moss opal is composed of hydrated silica. It contains water content, typically between 3% & 21%, giving the stone its slightly hydrated appearance.
The mossy patterns inside the stone are caused by manganese or iron oxides. These mineral inclusions form delicate structures that look like plant life, although they are purely mineral-based and not organic.
Moss opal (and all types of opal) is found mainly in Australia. It is also found in Mexico, Brazil and in parts of western USA.
It is 5.5 to 6.5 on the Mohs hardness scale.
All opals, including moss opal, are sensitive to heat, so avoid exposing them to high temperatures or sudden temperature changes. Don't use harsh chemicals or ultrasonic cleaners, as they can damage the stone.
If you live in a humid climate, it is ideal. If you are in a dry climate, you should store it in a plastic bag when not worn, to retain it's natural moisture.
Each stone has unique patterns, making every moss opal one-of-a-kind.
