Item Description

A very rare and excellent display quality thumbnail specimen of the calcium tin silicate, Stokesite from the famous Urucum Mine in Brazil. This locality is known for producing the finest crystals / specimens of Stokesite in the world. Most of the specimens you'll see are individual "balls" like this comprising dozens of thin bladed crystals. This piece features a spherical group of creamy-beige colored Stokesite, forming an attractive specimen. This species has been known since 1899, but samples are nearly impossible to obtain from any locality. Sometimes you can find them from Brazilian dealers, but that's about it. Interestingly enough, this species is actually named after a mathematician, who is the namesake for Stokes's law, describing the force acting on a particle moving in a fluid medium. A must have for any rare species collector or a serious thumbnail collector. From the collection of Mervyn Ford. Priced at $700 in the inventory
