Description

The apatite crystal is dark green - the first photo shows it with minor backlight, the second one under daylight. It is free-standing, exposed, sharp terminated and shows the very best luster. Below the apatite you can see well developed muscovite - the assemble is resting on a floater of albite, which is also well crystalized and very glossy. No significant damages to report.
