Moldavite
A variety of Tektite
What is Moldavite?
Moldavite is a natural glass that was formed as a result of a meteorite impact that occurred 15 million years ago in Europe. Being very rare and difficult to mine, moldavite is very valuable and extremely prized among collectors. Fragile just like any glass, it's commonly used with jewelry that doesn't face potential impact.
Uses & Applications
Moldavite is a very rare glassy mineral that is highly prized and sought after by mineral collectors and museums. The more translucent an example of this mineral, the more desirable and valuable it is. Despite its relative softness, this mineral is used in the jewelry industry mainly for uncut pendants. Beware, though — there are many imitations.
Healing Properties
Try clasping moldavite in the palm of your hand. Can you feel a rush of energy through your body? It's said to create an inner excitement that warms the body and soul. Moldavite is supposedly an emotional healing stone that brings forward suppressed emotions and allows you to deal with them, so they no longer negatively impact your life.
