Suolunite is a very rare calcium silicate mineral that forms deep within the Earth's crust near the mantle. Cystals are found in grayish-blue, honey yellow and colorless. This mineral is also distincly
piezoelectric. The only sources are Suolun, Inner Mongolia, China and Kulaski, near Doboj, Bosnia-Herzegovina and Al Khawd, near Masqat, Oman. Gems are extremely rare.
