JWHITE-35 - Garnierite - $ 50 SOLD Riddle Mine, Riddle, Riddle District, Douglas Co., Oregon, USA miniature, 4.1 x 2.4 x 2.3 cm ex. John White
This is a heavy rich specimen of garnierite. Apparently under modern reclassification this is no longer a species (news to me!). It is considered a mix of green nickel minerals formed from weathering and may consist of williamseite, nepouite, and pimelite.
