RM1651   Fluorapatite

La Celia, Jumilla, Murcia, Spain

From a find in the area of La Celia mines. This crystal is very rich in faces, doubly terminated, gem quality, very brilliant and with an excellent transparence. It is accompanied by numerous other smaller crystals. This locality is located in La Celia volcano where we find remains of a volcanic neck (chimney) and streams from Pliocenic age (1.8-5 million years). These mines have a special geological interest, as they contains an exceptional locality for fluorapatite in the volcanic rock "jumillite". Jumillite is a volcanic rock of the lamproite group, a variety of phonolitic leucitite, consisting essentially of diopside and leucite and, to a lesser content, by olivine, alkali feldspar and phlogopite.
