RM1738   Fluorite and quartz
CaF₂
  -  3. Halides

These fluorite specimens are particularly interesting as they show dodecahedral crytals, which is an uncommon habit for fluorite, with minor octahedral and cube faces. To give a touch of aesthetics, crystals have a marked geometric color zoning, revealing a purple replica of the larger crystal inside. Good transparence and brilliances. They are disposed on a quartz matrix. Really aesthetic.

Size: 6.3 x 5.0 x 4.7 cm.
Main crystal: 20 x 15 mm.
Found in 2017.
