MJ87Q6: Very aerial aggregate of bright tabular crystals that have very well marked faces of a flat dypyramid, strong color zoning, darker on terminal faces and clearer on the dipyramid and prism, forming the “steer eye” as it is popularly known in Panasqueira. The piece is a complete floater and is especially elegant due to the esthetic growth of the group on the matrix of Muscovite.
It is from one of the last great finds in Panasqueira, the year 2003.

Minas da Panasqueira, Level 2, Beira Baixa  Portugal

Specimen size: 9.5 × 7.2 × 2.7 cm = 3.7” × 2.8” × 1.1”

Main crystal size: 2.3 × 1.8 cm = 0.9” × 0.7”

N58WA0: Fluorapatite well positioned on its matrix of quartz covered with siderite. Although the color of the Fluorapatite is not intense the photo does not do it justice.
Minas da Panasqueira, Level 3, Beira Baixa  Portugal (1997)

Specimen size: 13 × 4.5 × 6.6 cm = 5.1” × 1.8” × 2.6”

Main crystal size: 1.5 × 0.6 cm = 0.6” × 0.2”

Main crystal size: 1.4 × 0.8 cm = 0.6” × 0.3”

NE43E7: Look out for this one: it is marvelous. The prismatic Fluorapatite crystals are large, aerial and have a great color that is somewhere between blue and green. That said please note that, as you can see in the detailed photo, there is a significant contact on one of the upper faces of crystals. This is where there used to be some Siderite (I know this as I removed it). When you display this specimen the contact is not visible, but you see it when you hold it in your hands. So the importance you give to this contact will affect your wish to have this one in your collection. For me, given the beauty and quality, the fact that there is a contact (this is not damage) due to the former Siderite is acceptable, especially given that it is very difficult to find such specimens at a reasonable price.
