Cassiterite with Scheelite.

Cassiterite with Sphalerite, Quartz and Siderite.
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?

Cassiterite with Zinkenite.
RJ47F8: Cassiterite with Zinkenite
A group of Cassiterite twins, very typical of Cornwall and on matrix. Needle crystals of Zinkenite accompany the Cassiterite. Although the mine that it is from is not given, it is the type of specimen that is hard to find.
Cornwall  England / United Kingdom (±1926)
Specimen size: 6 × 4.8 × 2.7 cm = 2.36” × 1.89” × 1.06”

Price: [SOLD]
Doubly terminated Cassiterite.
AE47Z1: Doubly terminated Cassiterite
Complete, untwinned, floater crystals showing the very well defined faces of two prisms and a dipyramid. The sample is from a known but very little disclosed Portuguese locality from which there have been scarce pieces of this quality.

Specimen size: 2.8 × 2.6 × 2.7 cm = 1.10” × 1.02” × 1.06”

Crystal forms a cyclic, dipyramidal twin, very well defined. It has brown color and it is translucent and very bright.

Twinned Cassiterite.
TC26J3: Twinned Cassiterite
A very interesting miniature both for the size of the crystal, considerable for Panasqueira, and because it is nearly transparent and has a very evident twin.
Minas da Panasqueira, level 2, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro  Portugal (±1978)
Specimen size: 2.6 × 2.6 × 2.8 cm = 1.02” × 1.02” × 1.10”
