Hypersthene
A variety of Orthopyroxene Subgroup

What is Hypersthene?
Hypersthene is prized by collectors for the pearly or copper-red play of color appearing along the surface of these grey stones when polished. Rarely, faceted gems are made, but the effect is not as brilliant as it is for cabochons or tumbled stones. "hypersthene" is considered to be an outdated name for its constituent mineral, but the term is still most commonly used in the gem trade.
Etymology & Origins
The name "hypersthene" comes from the Greek and means "over strength", and is an allusion to its being harder than the amphibole mineral hornblende (a mineral with which it is often confused).
Uses & Applications
Like bronzite, it is sometimes cut and polished as a gemstone.
Healing Properties
Hypersthene is often referred to as a magical stone and is believed to help in problem-solving. Many say the stone can allow for clairvoyance especially when used on the Third Eye chakra during meditation. It is believed that using the stone on any of the upper chakras will help a person find solutions to problems they are facing.
