Description

Very nice contrast between the blue apatite and the colorless quartz on a granite matrix, coming from this old quarry in La Fregeneda, a classic. It is very difficult to find larger and more perfect specimens because the quartz covers the apatite crystals and these are almost completely broken when trying to extract them.
