MD-215132 - Ellestadite-(F), Calcite - - Archived Commercial quarry, Sky Blue Hill, Crestmore quarries, Crestmore, Riverside Co., California, USA small cabinet, 5.1 x 4.0 x 2.7 cm.
5.1 x 4.0 x 2.7 cm. A large crystal of yellow fluorine-rich ellestadite to 1.5 cm, trapped in beautiful blue calcite. These are common enough as microcrystalline material from this locality, but few crystals of such size (and in good condition) are found. Quite exceptional for the species. NOTE: Texas Industries is the current owner of Riverside Cement and the cement plant there has been shut down since a week before Christmas 2008.
MD-271430 - Tobermorite, Ellestadite, Calcite - - Archived http://www.mindat.org/photo-38006.html. cabinet, 12.0 x 8.5 x 3.3 cm.
12.0 x 8.5 x 3.3 cm. Tobermorite and ellestadite are both very rare silicates. This fine cabinet specimen is very richly covered on both side by snow-white grains of tobermorite and sparse grains of tan-beige ellestadite in beautiful blue calcite. There are even a few vesuvianite crystals scattered about. Seldom available, in this size and in very rich and attractive material, this is from the Crestmore quarries of California. Compare to the specimen in the Natural History Museum, London, here: http://www.mindat.org/photo-38006.html. This is a superb piece for both species, you will see.
MD-48321 - Ellestadite-(F), Hemimorphite - - Archived Mun. de MapimÃ, Durango, Mexico thumbnail, .7 cm.
A truly amazing pseudomorph with SHARP blades up to .7 cm. Although small overall, this is the best example I have yet seen of this classic replacement which used to be called by the name of wilkeite. The pics say it all. 2.7 x 2.7 x 1.7 cm
RARE-09-26 - Ellestadite-(F) in Calcite - $ 350 Commercial Quarry, Sky Blue Hill, Crestmore, Riverside, California, USA miniature, 5.1 x 4.0 x 2.7 cm
A large crystal of yellow fluorine-rich ellestadite to 1.5 cm, trapped in beautiful blue calcite. These are common enough as microcrystalline material from this locality, but few crystals of such size (and in good condition) are found. Quite exceptional for the species. Although still collected, I have seen many years' worth of material found here on sporadic trips by friends, and I can say crystals like this are superb and rare. NOTE: Texas Industries is the current owner of Riverside Cement and the cement plant there has been shut down since a week before Christmas 2008.
