Grandidierite

Grandidierite has a unique blue-green color. This gemstone has been gaining attention in recent years as gem-quality gemstones were discovered in 2014. With a high Mohs hardness of 7.5, it can be enjoyed as everyday jewelry, but it is susceptible to impacts from certain directions, so care must be taken not to hit it too hard.
