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.
