Rosasite
A variety of Rosasite Group
What is Rosasite?
You may think that rosasite, given its name, is rose-colored. But this sky-blue-hued stone is actually named for the Rosas Mine in Sardinia, Italy, where it was first discovered. This uncommon mineral is mined for its zinc and copper content. The mineral's smooth - almost silky - crystals make it distinctive and attractive to collectors.
Uses & Applications
Rosasite is a source of copper and zinc, though it does not occur abundantly and is not the most popular ore of either of these minerals. Its rarity and bright blue color make it a desired collectors item and popular museum exhibit piece.
Healing Properties
Rosasite is believed to give hope and restore the love and joy in one's aura. It is thought to provide a direct link between the throat and heart chakras, helping a person give voice to their emotions. Many find it useful while repeating affirmations, as it is said to offer strength and determination as well as the positive energy needed for transformation.
