I just went through my book looking for any with similar looks & came up with this one. It is called Variscite.
Hydrated phosphate of aluminum& iron.
color & luster: pale green to emerald green, also bluish green, colorless: vitreous, waxy. Lots of other info in the book. So check out Audubon Society Field guide to North American Rocks & Minerals. Don't know if this is what your rock is, but it certainly has the same look.
