Eosphorite,  a beautiful and little-known collectors gem.  Eosphorite was discovered in 1878 and was given its name by George J. Brush and Edward S. Dana.  The name comes from the Greek έωσφορος (or: heōsphoros) meaning "dawn-bearer."  It was given this name due to its colour. Eosphorite may be rose pink, red, pale brown, golden brown, medium to dark brown, light pink, light yellow, or colourless.  It has a hardness of 5 which is comparable to Apatite. Eosphorite is generally a secondary mineral found in phosphate bearing granitic pegmatites. It may be transparent to translucent and have a vitreous, sub-viterous, or resinous luster. Eosphorite may be found in: Russia; Sweden; Finland; Germany; Portugal; Afghanistan; Pakistan; Rwanda; Mozambique; Brazil; Argentina;  Australia; the Yukon Territory in Canada; and the states of Maine, New Hampshire, South Dakota, Connecticut, North Carolina, Arizona, and California.
