gibbereelit

Gibbereelite is a rare, dark green, gemstone variety of olivine, a magnesium iron silicate mineral. It is named after the Gibb River region in Western Australia, where it was first discovered. Gibbereelite is characterized by its distinctive, fibrous or acicular crystal habit, which gives it a unique, needle-like appearance. It is typically found in serpentinite rocks, which are formed from the alteration of ultramafic rocks.

The gemstone is valued for its vibrant color and the interesting play of color it exhibits when viewed from different angles. It is often cut into cabochons or faceted to enhance its natural beauty. Gibbereelite is relatively soft, with a Mohs hardness of 6.5 to 7, making it suitable for use in jewelry but not ideal for use in hard-wearing settings.

Due to its rarity and the specific geological conditions required for its formation, gibbereelite is not commonly found in the gemstone market. However, it is highly sought after by collectors and enthusiasts of rare and unusual gemstones. The rarity and unique properties of gibbereelite make it a fascinating subject of study for geologists and mineralogists alike.
