   A CLASSIC, OLD-TIME, fluorite specimen from the famous Weardale area of England. This very fine, two-sided, mounded piece features super lustrous and glassy, interpenetrating fluorite cubes to 2.1 cm on a sliver of limestone matrix. Typically, for many Weardale fluorites, the green cubes turn purple (natural fluorescence) in nearly all lighting conditions. The fluorites really are green! Very trivial damage, overall, to this fine old-timer. SUPER fluorescence. Old piece from workings either in the early 1800s or mid-1900s. Ex. Roman Gaufman and George Elling Collections.

Image is of adamite crystals and source information follows: These scintillating, gemmy, sea-green cuprian adamite crystals in rounded aggregates beautifully line the vug in the sculptural crust of sturdy gossan matrix in this very aesthetic specimen from the 2008 finds at the Mina Ojuela. Classic, very high quality cuprian adamite with excellent color from this noted locale. This is one of the prettier large plates of this material from the find. Ex. Brent Lockhart Collection.

An image of a large floater crystal of spessartine from Brazil. It is shown here backlit (strongly) to emphasize not only the super gemminess through and through, but also the amazing architecturally stepped surfaces so distinctive of this find. This specimen is complete and undamaged, with the incredible terraces all the way around. Locality: Minas Gerais, SE region, Brazil. Used with permission.
