A striking specimen composed of numerous prismatic, highly faceted cassiterite crystals with exceptional luster and translucency, displaying a honeyed hue. This is an excellent old specimen from the little-known Seal Hole mine in Cornwall. A very showy and uncommon specimen in this mine.

Specimen very rich in cassiterite crystals, very bright, richly faceted and of an intense dark brown color. The specimen has been repaired without affecting the interest of the specimen, from my point of view. A very interesting piece from these tin mines of the St Agnes mining district, an English classic.
