Margarite from Chester Emery Mines, Chester, Hampden Co., Massachusetts, USA [db_pics/mdpics/MD-202074a.jpg]

13.9 x 12.0 x 8.9 cm. This remarkable specimen features a large display face the size of a big grapefruit covered with upright, platy crystals of margarite. It is extremely rare for margarite to crystallize and 99% of all margarite from there is massive xline material. Margarite is typically found in either masses of platy crystals, intergrown, or what is typical for the location, veins or veinlets. In general, the thicker the better at this location with some of the thicker veins of margarite reaching an inch or two, and maintaining a pink color. This one is atypical, since the margarite looks to have formed along a slip face, allowing the 3D growth; the one here is thus a little unusual based on other historic specimens from this locality in East Coast collections (per Jim Chenard, pers. comm.). It also has some diaspore and rutile in association. Ex. Academy of Natural Sciences Philadelphia Collection.

Margarite from Chester Emery Mines, Chester, Hampden Co., Massachusetts, USA [db_pics/mdpics/MD-210786a.jpg]

6.5 x 3.8 x 3.2 cm. Margarite is a rare mica group mineral. This rich and fine old-time piece features pearlescent, brownish, stacked margarite plates aesthetically embedded on all side of the matrix. This classic specimen is from the historic Chester Emery Mines of Massachusetts, where margarite was discovered in 1864. The collection this came out of was a museum stash dating to prior to World War I.

Diaspore, Margarite from Mugla Province, Aegean Region, Turkey [db_pics/mdpics/MD-215043a.jpg]

3.8 x 2.6 x 2.3 cm. Gem diaspore from this classic old locality in Turkey sets the standard for the species. This specimen hosts a 3.7-cm crystal, doubly-terminated crystal perched in matrix of crystallized margarite. Matrix specimens are very rare for this locality. Usually these come out only as loose crystals, loose floaters perhaps.

This remarkable specimen features a LARGE display face the size of a big grapefruit covered with upright, platy crystals of margarite. It is extremely RARE for margarite to crystallize anyways and 99% of all margarite from there is massive xline material. Margarite is typically found in either masses of platy crystals, intergrown, or what is typical for the location, veins or veinlets.

DIASPORE on MARGARITE from Mugla Province, Aegean Region, Turkey [db_pics/pics/rare-09-05d.jpg]

Gem diaspore from this classic old locality in Turkey sets the standard for the species so far as I am concerned. This specimen hosts a 3.7-cm crystal , doubly-terminated crystal perched in matrix of crystallized margarite. Matrix specimens are VERY RARE for this locality! Usually these come out only as loose crystals, loose floaters perhaps. Matrix specimens are most uncommon. This can be displayed horizontally or vertically to equal effect.
