The Diamond
Diamond is the best known gem. It is known as the “king of gems” for its brilliance and for being the hardest mineral on earth. (Foa, p.50) Its characteristics enable it to be used for many different purposes. Since diamonds are the hardest gems on Mohs’ scale, they make useful tools for industrial purposes, such as drilling hard materials. However, they are quite rare, which makes them very valuable. Their beauty and brilliance make them perfect for jewelry. Diamond is made up of carbon. Another form of pure carbon is graphite. Graphite is the stable form of carbon, found at the earth’s surface. Despite the fact that they have identical chemical composition, the two minerals are drastically different. Diamond is the…show more content…

This is an especially common occurrence in Brazil, where diamonds are sometimes found in which many tiny crystals are tightly packed together. These kinds of diamonds, which grow in bunches are called carbonados. (Fisher, p.52) Carbonados are usually used in industry. Diamonds are very important in industry because they are used for the manufacture and use of various precision instruments. These instruments are employed in grinding and polishing glass, polishing ceramics, stones, etc. Diamond drill crowns are used in the oil mining industry to drill through the earth to the oil.

Answer:
- Diamond is one of the best-known and most sought-after gemstones. They have been used as decorative items since ancient times.The hardness of diamond and its high dispersion of light—giving the diamond its characteristic "fire"—make it useful for industrial applications and desirable as jewellery.Diamonds are such a highly traded commodity that multiple organizations have been created for grading and certifying them based on the "four Cs", which are color, cut, clarity, and carat.
- Other characteristics, such as presence or lack of fluorescence, also affect the desirability and thus the value of a diamond used for jewelry.
- Diamonds are used in engagement rings. The practice is documented among European aristocracy as early as the 15th century, though ruby and sapphire were more desirable gemstones. The modern popularity of diamonds was largely created by De Beers Consolidated Mines, which established the first large-scale diamonds mines in South Africa. Through an advertising campaign beginning in the 1930s and continuing into the mid-20th century, De Beers made diamonds into a key part of the betrothal process and a coveted symbol of status.The diamond's high value has been the driving force behind dictators and revolutionary entities, especially in Africa, using slave and child labor to mine blood diamonds to fund conflicts.
- Though popularly believed to derive its value from its rarity, gem-quality diamonds are quite common compared to rare gemstones such as alexandrite, and annual global rough diamond production is estimated to be about 130 million carats (26 tonnes; 29 short tons).
