Fluorapatite on Siderite
Miniature, 5.0 x 5.0 x 3.7 cm
Panasquiera, Castel Branco Dist., Portugal
A matrix of flattened rosettes of lustrous, tan colored siderite is the host for a single, glassy and gemmy, doubly terminated, color-zoned fluorapatite crystal, 2 cm across. A 3 mm thick purple, band in the center is sandwiched between two colorless bands. Two colorless quartz crystals are emplaced on the underside of the specimen. The specimen is nearly pristine with just a very small bruise on a single crystal edge. A classic example of this rare old style we used to call the "purple sandwich," in a balanced miniature-sized specimen. ex. Dr. Joan Massague Collection.
