Feldspar is a rock-forming mineral valued for its well-formed crystals, vitreous luster, and attractive natural colors ranging from white and cream to pink and green. Specimens from Brazil are known for their excellent crystal quality and frequent association with minerals such as quartz, tourmaline, and mica in granitic pegmatites.
With a hardness of 6–6.5 on the Mohs scale, feldspar is a durable mineral widely collected for its geological significance and natural beauty.
Each specimen displays unique crystal formations, textures, and natural variations, making every piece one of a kind.
