A very sharp cluster of two crystals with high luster and saturated color, unusual for a thumbnail when most are just single crystals. Small calcite matrix is attached. From the private collection of internationally known wildlife artist Gamini Ratnavira (http://www.gaminiratnavira.com), who started collecting small mineral specimens many years ago after exposure to the mineral community in his residence of Fallbrook, California. For a number of years, Gamini made mineral watercolors for private collectors on commission for $500 each. For his own enjoyment, he also made watercolor paintings of all of his pieces, and the painting is included here with the specimen (7 x 7 cm paintings set in custom 14.5 x 14.5 cm frames).
