About StarkeyiteHide

Formula:
MgSO4 · 4H2O
Colour:
White to very pale yellow or pale greenish white.
Lustre:
Dull, Earthy
Hardness:
2 - 3
Specific Gravity:
2
Crystal System:

Member of:
Name:
Named in 1956 by Oliver Rudolph Grawe for the type locality, the Starkey Mine in Madison County, Missouri, USA.
Rozenite Group.
Closely related to cranswickite.

This is a rare mineral, found at only a few localities, then it is usually found as white to very pale yellow or very pale greenish white powdery efflorescences. Good crystals are extremely rare, perhaps unheard of.
