In the late 1970’s a marvelous find of gem minerals was made at Virgem da Lapa, including the world’s finest herderites. This specimen features a 2.6 cm long, translucent, blue- gray, gemmy and lustrous herderite with tiny green elbaites and pink lepidolite crystals. It is a very attractive miniature and has a definitively more blue hue to it than the generally purplish ones for which the mine is famous. It is complete all around save for a few very trivial contacts. He got it in Brazil himself, while teaching math in Rio. 3.7 x 2.8 x 2.5 cm
An extremely rare thing, this! Green hydroxylherderites of this odd tabular form were found just once, about 1988. I got this one from Herb Obodda. This one features a 2 x 2 x 1 cm crystal perched on a knob of albite, with a small schorl hanging off one side for accent from that view; and the beautiful white of the albite ball presenting on the other side. There is a smaller, secondary crystal beneath the major crystal. 3.3 x 3 x 2.3 cm
This is one of the great crystals from the first and best find of purple herderites at Xanda mine in october of 1978, as shown in the Bancroft bookGem & Crystal Treasures. It has GLASSY lustre on all sides, is pristine, and is perfectly and 3-dimensionally formed. It is very transparent! Moreover, the color is INTENSE purple, not the usual pale lavender hue. Bill Larson and Ed Swoboda personally flew this specimen to New York and sold it to noted collector John Saul, who owned it until recently. It is 360 grams - lightweight mineral, i guess. you expect it to have more heft, visually, as the visual impact is both stunning and "weighty" . This is the finest crystal of the species from this find that I have seen outside of a very few museums, hands down. I believe it to be one of the most significant pieces I have had to offer. 7.5 x 7.5 x 4.5 cm
Hydroxylherderite on topaz. This remarkable example of paragenesis is aesthetic and beautiful, as well. Summer of 2003. 3 x 2.9 x 2.2 cm
