4" x 2 3/4", 10.2cm x 7cm. An exceptional specimen of Chalcanthite (hydrous Copper Sulfate) from recent diggings at the Planet Mine in Arizona. Bright electric blue crystals, many of them slightly curved, jut proudly from the minor matrix--this specimen wants to be on display!. Individual crystals to 1 1/4", 3.2cm, coat nearly the entire specimen, filling in seams in the host rock.

The color on this specimen is incredibly amazing--one of the brightest blue's I personally have ever seen from the Planet Mine, one of the largest specimens I have ever had (of Chalcanthite from the Planet Mine), and truly a top-shelf specimen for the collector of fine minerals.

The collector who decides to bring this specimen home will indeed delight in this purchase, and it will certainly be the topic of discussion when shown off :-) Specimen will be overpacked for shipping, and insurance is included. This specimen collected Jan. 2012. Labeled and ready for your display.

This is not 'smelter-chimney' recovery, or a lab-made mineral, as many Chalcanthite's on the market today are. Chalcanthite is a primary ore of Copper at the Planet Mine. The color has not been enhanced or treated in any way, this is how the mineral occurs naturally, and this is how the specimen came out of the ground.
