This is truly a rarity. Coming from Engineer Fernando Soares Carneiro, it is an isolated Cassiterite crystal, a floater of very good size, which comes from a locality about which I, personally, knew almost nothing, besides that it was part of the group of tin mines in the Tras-os-Montes area.
In short, this is a super-rarity and its quality, for such a little known locality, is reasonable.
