Eclogite

Eclogite is a rare type of metamorphic rock that is composed of greenish-colored amphibole and pinkish-colored garnet. It gets its name from the Greek word for “select”, because it was once thought to be the perfect rock for making cameos and other jewelry.

Eclogites are found in ancient metamorphic terrains, such as the Adirondack Mountains in upstate New York, USA, and the Himalayan mountains of Nepal. The rocks are formed when oceanic crust is subducted (forced) under a continent and exposed to high temperatures and pressures. Eclogite is also sometimes used as a gemstone or ornamental crystal. Small eclogites can be faceted into beautiful gems, while larger ones may be cut into cabochons (smooth, rounded stones) or carved into ornamental objects.

Eclogite is a relatively rare stone, but it is prized by collectors and gemstone enthusiasts for its unique colors and interesting history.
