SV3230ETF: Cassiterite with Quartz
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.

Cassiterite with Quartz and Siderite.
RZ26T8: Cassiterite with Quartz and Siderite
Very bright twinned crystals of Cassiterite, with neat transparency and implanted on a group of transparent Quartz crystals. We believe that this sample is not from the classic mining area of Panasqueira but from a nearby zone named “Vale da Ermida” as its appearance matches exactly the shape of the samples found there several years ago.

Price: [SOLD]
Cassiterite with Quartz and Siderite.
AD96Y6: Cassiterite with Quartz and Siderite
Group of bright Cassiterite crystals forming complex cyclic twins. They are on a matrix of transparent Quartz crystals with some rough Siderite. This sample was in the Folch duplicates collection, whose label we’ll send to the buyer. It has an added interest because it is from Vale da Ermida, a zone somewhat away from the main mining area and is currently abandoned and awash.
Vale da Ermida, Panasqueira, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Centro  Portugal (±1964)
Specimen size: 7.7 × 5.7 × 4.9 cm = 3.03” × 2.24” × 1.93”
