Hydroxylapatite with Albite

An outstanding single crystal of the rare phosphate Hydroxylapatite is perched on the matrix of massive creamy-white Hydroxylapatite richly coated with blades of Albite feldspar.  This unusual specimen, from Oksøyekollen quarry in Snarum, Buskerud, Norway, has one main Hydroxylapatite crystal 5 cm tall by 3.5 x 3 cm in section and is near-perfectly terminated.  The Hydroxylapatite is a chalky-white with a dull, yet satin porcelaneous lustre.  A great specimen of a seldom seen species and of museum display quality.
