TC2290NRF: Hydroxylapatite on Quartz

Isolated Hydroxylapatite crystals on a matrix of Quartz crystals. Hydroxylapatite forms crystals with a very flattened bipyramidal shape, almost lenticular. They are translucent and have a nice green color, with a much paler greenish yellow zoning in the center.
Sapo Mine, Ferruginha, Conselheiro Pena, Vale do Rio Doce, Minas Gerais Brazil
Specimen size: 19.8 × 12.1 × 6.2 cm = 7.80” × 4.76” × 2.44”
Price: €290 / US$310 / ¥41160 / AUD$460

TH46H4: Hydroxylapatite with Orthoclase

This Apatite has finally been correctly identified as the species Hydroxylapatite, very less common than Fluorapatite. Crystals, on a matrix of Orthoclase, are flat hexagonal dipyramids with almost no prism faces, a habit that is not often seen with Apatite. Faces of a short prism can be seen on this crystal, a rarity with this material. The Hydroxylapatite is also attractively color zoned.
This specimen's photo has been reviewed and published in the magazine ‘Mineralogical Record’ on page 286 in the volume 40, number 4.
