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]

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”

JFD142AO6: Cassiterite with Sphalerite, Quartz and Siderite

One hell of a Cassiterite! Very large for Panasqueira, very lustrous, and sitting well on Sphalerite crystals that are associated with Quartz crystals, one of them broken, but the others recrystallized, and with small Siderite crystals. Who said that Panasqueira cassiterites did not reach world class status?
