Here we have a large Diopside Crystal showing a high grade crystal in among a matrix of lower grade crystal. So over all not the same grade as the smaller ones elsewhere on the site. It is a good handful! There is little inclusions and a lovely rich emerald green colour. Dimensions are for the larger.
This crystal is said to improve intellect and encourages the desire of one to learn. It is helpful in alleviating aggression or stubbornness. While in turn, it enhances love and commitment. Although I expect you will be a geological collector who buys it as its hard to get.
Many people love their crystals in natural state so this diopside crystal will be loved!
