Altyntobe deposit field:One of the rare deposits of unique stone aschirite-dioptase is located approximately 120 kms to the east of Karaganda. This mineral has such purity and deepness that only an expert can differentiate it from emerald. According to the legend, Bukhara merchant Ashir discovered the deposit at the second half of 18th century and thought that it was emerald. The latest analyses show that the “stone” resembles emerald only by its view, not by hardness. Later on, German mineral scientist Abraam Gottlib Verner gave this mineral the name “copper emerald”. Aschirite-dioptase is mainly a collection stone and no good for the making of jewelry. However, the mineral still has great value for collectors as it is rarely found on earth.
