Description: Carbonado, commonly known as the “black diamond”, is the toughest form of natural diamond. It is an impure form of polycrystalline diamond consisting of diamond, graphite, and amorphous carbon. It is found primarily in alluvial deposits in the Central African Republic and in Brazil. Its natural color is black or dark grey, and it is more porous than other diamonds.
Characteristic: Carbonado or Black Diamond, has a Mohs Scale of 10. Carbonado diamonds are typically pea-sized or larger porous aggregates of many tiny black crystals. The most characteristic carbonados have been found only in the Central African Republic and in Brazil, in neither place associated with kimberlite, the source of typical gem diamonds. Lead isotope analyses have been interpreted as documenting crystallization of carbonados about 3 billion years ago. The carbonados are found in younger sedimentary rocks.
Appellation: Diamond takes it’s name from the ancient Greek adamas, or “proper, unalterable, unbreakable, untamed”.
History: Carbonado doesn’t has a specific history, since it is not confirmed. So here are some proposed hypotheses are as follows:
- Direct conversion of organic carbon under high-pressure conditions in the Earth’s interior, the most common hypothesis for diamond formation
- Shock metamorphism induced by meteorite impact at the Earth’s surface
- Radiation-induced diamond formation by spontaneous fission of uranium and thorium
- Formation inside an earlier-generation giant star in our area, that long ago exploded in a supernova.
- An origin in interstellar space, due to the impact of an asteroid, rather than being thrown from within an exploding star.
To make this article more interesting i will talk a little about diamond history. Early references to diamonds in India come from Sanskrit texts. The Arthashastra of Kautilya mentions diamond trade in India. Buddhist works dating from the 4th century BC describe the diamond as a well-known and precious stone but don’t mention the details of diamond cutting. Another Indian description written in the beginning of the 3rd century describes strength, regularity, brilliance, ability to scratch metals, and good refractive properties as the desirable qualities of a diamond. Golconda served as an important center for diamonds in central India. Diamonds were traded to both the east and west of India and were recognized by various cultures for their gemological or industrial uses.
Origin And Special Features: Diamond can be nearly any color, but their most common color are brown and yellow. With make the black diamond rather rare, but they aren’t fully black. The dark appearance is due to numerous dark inclusions that give the darkness of the stone. It’s part of the carbon family and is the hardest substance known. If the color is strong enough, a stone may be referred to as a fancy colored diamond by the trade. There are Natural fancy color diamonds and Synthetic Color Diamonds. For more information on any of these subjects please refer to the Index.
Symbol and Lore: For the longest time it has been believe that diamonds possess several supernatural powers:
- A diamond gives victory to he or she who carries it bound on his left arm, no matter the number of enemies.
- Panics, pestilences, enchantments, all fly before it; hence, it is good for sleepwalkers and the insane.
- It deprives lodestone and magnets of their virtue (i.e., ability to attract iron).
- Arabic diamonds are said to attract iron greater than a magnet.
- A diamond’s hardiness can only be broken by smearing it with fresh goat’s blood.
- In traditional Hinduism one should avoid contact with a diamond whose surface area is damaged by a crack, a crowfoot, a round, dull, speckled area, or which is black-blue, flat, or is cut other than the (ideal) hexagonal shape.
Because of their extraordinary physical properties, diamonds have been used symbolically since near the time of their first discovery. Perhaps the earliest symbolic use of diamonds was as the eyes of Hindu devotional statues. In Hinduism Indra uses Vajrayudham or the thunderbolt as his primary weapon. Vajra is the word for diamond and ayudham means weapon in Sanskrit. Another name for it was Agira which means fire or the sun. In fact there are 14 names counted to be given to a diamond in traditional Hinduism.
