An off-matrix, sharp, perfectly terminated crystal of the rare calcium apatite mineral Hydroxylapatite from the classic Norwegian locality of Oksøyekollen quarry at Snarum in Norway. The chalky-white crystal has a slightly rough surface texture which gives it a non-lustrous, matt appearance. A smaller Hydroxylapatite crystal has developed within the main crystal in parallel growth and emerges as a 1 x 1.1 cm termination out of one of the main crystal’s termination faces. The smaller crystal has a pyramidal hexagonal termination whereas the main crystal has a flat pinacoid face. An excellent example of this unusual mineral, interesting also in that over fifty percent of human bone is composed of this species.
