A rare example of the classic phosphates from this locality, which are seldom seen as anything but smudges. Yet, this piece is actually quite rich and attractive!

Strengite, Rockbridgeite from Leveäniemi Mine, Svappavaara, Kiruna district, Lappland, Sweden [db_pics/mdpics/MD-112592a.jpg]

A gorgeous miniature with high quality and good relief both - a rare combination. The strengite (purple) is of extremely high quality and size for the material (to 6 mm). The rockbridgeite though, is probably even better all things considered as this species is usually just the associated mineral and not so dominant in its own crystallization that it stands out so nicely as here. 3.5 x 2.8 x 2.6 cm

Strengite, Rockbridgeite from Leveäniemi Mine, Svappavaara, Kiruna district, Lappland, Sweden [db_pics/mdpics/MD-173724a.jpg]

4.1 x 4.1 x 2.5 cm. A showy combination specimen of phosphates from the famous Leveaniemi Iron Mine of Sweden. Lustrous, lavender strengite spheres to 3 mm are aesthetically and richly scattered with sea-foam green spheres of rockbridgeite to 4 mm in a 3-dimensional vug atop massive hematite matrix. These specimens were collected in the mid-1980s and the mine is now closed. Ex. George Elling Collection.

7.3 x 6.4 x 4.0 cm. Hureaulite is an uncommon phosphate. This fine specimen features a well-placed, wide vug in the V-shaped matrix richly lined with glassy, pastel-pink hureaulite crystals on a quartz-rich matrix from the new find at the Cigana Mine, Brazil. The crystals are gemmy, superb and reach 5 mm. A surprise on the back features a vug lined with dark green rockbridgeite crystals, another uncommon phosphate.

An attractive specimen by any standard for the species, but ESPECIALLY for such an esoteric phosphate locality as this one! This piece features a curved blet of sharp red hureaulite crystals to about 6mm, associated with other phosphates, all on massive quartz. It was obtained in trade from the collector who told me that he got it several decades ago and it was one of the better such specimens. I certainly haven't seen anything remotely comparable on our market, to compare it to, and so I really tend to trust his comments in that regard. 10 x 6.4 x 5.4 cm

Hureaulite, Reddingite, Rockbridgeite from Cigana claim (Jocão claim), Galiléia, Doce valley, Minas Gerais, Southeast Region, Brazil [db_pics/mdpics/MD-23705a.jpg]

An extremely rich and excellent CABINET specimen of highly lustrous salmon-pink hureaulite crystals to 8 mm with reddingite (brown) and rockbridgeite (black). The Jocao Mine of Minas Gerais produces some of the very finest crystals of these uncommon phosphates. Good rarity and also attrractive! 10.7 x 5.5 x 5.2 cm

8.4 x 5.8 x 3.5 cm. Hureaulite and rockbridgeite are uncommon phosphates. This fine, 3-dimensional specimen is solidly covered with glassy, pastel-pink hureaulite crystals on a matrix of massive hureaulite from a recent find at the Jocao Mine, Brazil. The crystals are gemmy, superb and reach 5 mm. A large pod of layered, lustrous, dark geen to gray to black rockbridgeite is a complimentary stark contrast. Ex. Wesley Stark Collection. A good piece from finds of the 1990s.
