Adamite Var. Manganoan
Ojuela Mine, Mapimi, Durango, Mexico
Thumbnail, 2.0 x 1.3 x 0.9 cm
Ex. F. John Barlow
In 1980 a wonderful find of manganoan adamite was found at Mina Ojuela (initially mislabeled as cobaltian-rich). Good specimens today are exceedingly rare and pricey. This superb sharp thumbnail specimen features a striking, well-isolated cluster of lustrous and translucent, crystals to 1.7 cm in length. The top portion of each crystal exhibits the classic lovely rich purple color which has made this the single most famous pocket of its species. They are absolutely unique specimens and found nowhere else in such quality before or since the early 1980s. This specimen carries on its back the glued number from the F. John Barlow thumbnail collection (part of which I obtained in 1998 and sold to Jim White, at that time)
