Diamonds have been known since ancient times as one of the stones of commercial value. Diamonds grew in popularity in the 19th century as global production increased, trade routes improved around the world and scientific methods of cutting, polishing and the global monopoly of the commodity by some companies. Diamonds have many physical properties, but the best known of hardness and hardness is alone among all the materials on the degree of hardness 10/10 in the scale of degrees (Moss) global stones (hardest 10 - and weakest 1). The crystalline system, in particular, diffuses light, but in diamonds it is considered high for light. For this reason, diamonds are a valuable stone in the jewelery industry as well as other industrial uses such as the use of diamonds on top of deep well drilling pipes such as water, oil and natural gas in addition to its use in electronic devices, medical devices, industrial equipment, glass cutting and others.
For the word diamond
The word (diamond) is derived from the ancient Greek word "Adamas" meaning solidity and "subject to adaptation" to its hardness and if we want to trace the effect of the Greek word then its origin came from the ancient eastern languages and then entered into Greek and then Latin, but the Greek meaning is the one that left its impact on Stone science and contemporary geology, and in most modern languages. The Greek word "Adamo" has been translated as "Adamas" and there are several translations of the word that came descriptive from Greek to English, "adamas", "I tame" or Adamas" has been used as a synonym for "malleable" or "hard to break", but it is difficult to guess at any point in history. The meaning was the element chondrum or sapphire, chemically known as (aluminum oxide) is the second element after the diamond in terms of hardness. As for Plato, the ancient Greek philosopher defines philosophy in the terms jewels and he meant that meaning diamond, and Plato mentioned diamonds in his many writings, especially what came in his book (Stones) and from here it was taken, quoted and quoted by other civilizations from the Greek every civilization according to the perception and understanding and translation of the meaning and not its literal, but the Arabs They have transferred it as it is, it is believed ?! With the replacement of the Day with the Lam, especially in the Abbasid era, when the largest translation movement known to humanity existed, that translation included the human sciences and knowledge that other civilizations knew, while before that it was known as the Moon, the Arabs used to call the word Durr a lot of precious stones for their similar colors and characteristics.
The origin of the word diamond in the Arabic language did not come from the adjective or adjective (referred to as subordination). It is the Arab translator of Greek dhimmas and they misrepresented it when Arabizing the heart of the dal to the mother, for the convergence of its image, its exits and its harmony when the word and when speaking. It is also said that the nomadic nomadic Arab tribes in Africa and the Middle East used the word thaamas or diamonds and they were pronounced (the word or the diamond) and the word was singular according to the dialect. In these areas, when they expanded their trade between them and between India and Europe, they used these rare stones for financial intermediation or for commercial exchange, as the first material currency the world has known, and diamonds were also traded as a currency in eastern and western India after its importance was noted for circulation and use.
