This is why crystals of calcite or other carbonate minerals are so often found with dioptase, examples of which are the dioptases from the type locality of Altyn Tyube, Kazakhstan and those from Tsumeb, Namibia- the former most often occurring on beds of white calcites and the latter being associated with many carbonates such as calcite, dolomite, and smithsonite.

The Dioptases themselves are gemmy and lustrous, with a rich emerald-green color and the 'fire' that is so coveted. The largest of these is about 1.2 cm long. One side of the specimen even has a partial oxide coating on many of the crystals, which add a very attractive contrast, ...

The stone town of Kuklica is an area consisting of over 120 naturally formed stone pillars, located in the village of Kuklica, near Kratovo in North Macedonia. Kratovo, which lies on the slope of Mount Osogovo, is itself located in the basin of an extinct volcano and hosts the Plavica (or Plavitsa) deposit, which has been mined since Roman times.

mined. Petrunov et al. (2001) published prelimi-nary microscopic and microprobe data of the oc-currence of the platinum group elements (PGEs) within the Bučim porphyry copper deposit for the first time. An increased content of Pd as well as Pd-mineralization (PGM) was established in the Cu-Au ores of the deposit in Bučim, Macedonia.

There are a limited number of commercially available diamond mines currently operating in the world, with the 50 largest mines accounting for approximately 90% of global supply. Diamonds are also mined alluvially over disperse areas, where diamonds have been eroded out of the ground, deposited, and concentrated by water or weather action. . There is also at least one example of a heritage ...
