Vote for your favorite mineral in #MinCup26! - Sphalerite vs. Anorthite Both zinc ore Sphalerite and calcium plagioclase feldspar Anorthite have perfect cleavage that will split cleanly if you hit them with a hammer, but only one can claim a larger split of your votes!
Transparent, gem quality and mostly flawless kunzite has been found as a single specimen (~4x4x1 cm) at the Dunton Quarry. Pink spodumene that is not of gem quality does not qualify as kunzite.
Quality for species:
Excellent - world class for species or very significant. (!!)
