A recent study showed that nomadic tribes living in Central Asia were 2,000 years ago, using diamond exercises in production of chains, bracelets and pendants. Diamond, is the most difficult natural material on the planet, used today, but the use of it in ancient times is probably very popular. The study was published in the Journal of Archeology and Anthropology.

Previous studies show that the perforation of particles using diamond exercises appeared in the bronze era of the civilization of the Indus valley. Some scientists also believe that ancient Egyptians could use diamonds to drill granite in the third millennium BC.

Of the 41 particles, scientists have found traces caused by diamond exercises when creating holes. According to the authors of the study, the goldsmith, clearly used, used a single diamond drill, had a diamond on the drill locomotive to start creating a hole. And then, they switched to a narrower diamond drill with two diamonds with a symmetrical position on the tip of the drill to complete the work.
The trace of the same technology was discovered on particles from the KVA Mgogo parking lot in Tanzania, although they were carried out centuries later.
The researchers also noted the significant differences between the methods used in Bactria and the visible methods on similar particles from the Indus valley. This shows that the relics in the Rabat cemetery are not imported from India or Pakistan, as before, but can be done on the spot. This, in turn, pointed out that diamond exercises were used about 2000 years ago in a large part of South and Central Asia.
