Miniature, 5.6 x 5.3 x 4.7 cm
Tantara, Katanga, Republic of the Congo
Ex. Edward Swoboda
SOLD
WOW! This is a very rare specimen! These were found in the early 1980s, and the specimen consists of small calcite crystals on dioptase, that were completely replaced by the copper mineral plancheite and turned a rich blue in color. This is only at ONE end of the piece. AT THE OTHER END, the calcites have been replaced by chrysocolla, I think; or at least so heavily coated one cannot tell and its a moot point visually. This is a very interesting, colorful, and fun specimen from the prominent pseudomorph collection of Ed Swoboda (see MinRec nov/dec 1997). He sold to Carter Rich in 1999, who sold this to George Loud right after, and it now is coming back to the market.
