Diamond is a kind of mineral composed of carbon, it is the hardest substance in nature. It is widely used as cutting tools in handicraft and other industries. As a valuable gemstone, Graphene can be made into synthetic diamond under high temperature and high pressure.

Property One: The Simplest Gemstone

Diamond is a nonmetallic mineral composed of natural element--carbon. Its impurity element is less than 0.05%. Other transparent diamond are minerals composed of multielements.

Property Two: The Hardest Substance

If we take Moh's hardness (relative hardness) as a criterion to measure ten kinds of minerals, then diamond hardness is 10, the hardest one. While by Novartis value (absolute hardness), the unit is kg/mm, diamond is 8000, fused alumina is 2000, quartz is 1000. As a result, diamond is still the hardest. So diamond is the hardest solid material in nature.

Property Three: The Most Stable in Density

Due to its simple chemical composition and tight structure, diamond has the biggest stability in density. When it contains impurities, the density ranges around 0.01% of the original diamond. This property is of special significance to gemstone identification.

Property Four: Highest Thermal Inertia

Thermal Inertia means the property of keeping substance in thermal motion state. The higher the thermal inertia, the harder it would be to change thermal state. Diamond has the highest thermal conductivity and thermal inertia that no substances can match. This provide evidence for thermal test equipment design, with which diamond and other gemstones can be indentified effectively.

Property Five: The Most Strategic Material

Pure diamond is the best nonconductor, while diamond with impurities (such as Ⅱb-type diamond) is an electronic semi-conductor that is resistant to 1000℃ aggressive media (such as alkaline liquor and acid liquor) and stands high radioactive radiation. Diamond can be applied in engineering industry, laser technology, electronics, acoustics, chemistry, medicine, etc. It is mainly applied in integrated circuit and cold-cathode lamp in that it does good to downsize equipment exterior and improve computer operating rate by a level.
