Characteristics Of A Diamond

Diamonds, the hardest mineral on the planet, are made out of carbon. They are carbon-based solids with atoms arranged in a diamond cubic crystal structure that occur naturally. Diamonds are the most popular and expensive gemstone; it is usual in many cultures to propose to a female with diamonds, which drives up demand. Each carbon atom is surrounded by four other carbon atoms connected by covalent bonds, the most powerful of all relationships. 

Structure of diamond:

A crystallographic structure exists in diamonds. It has a cubic structure. The face-centred lattice or FCC, is the crystal form of a diamond. The lattice form of the diamond is a face-centred lattice or FCC. The three kinds of lattice structures are  Face-centred or FCC lattice structures, body-centred or BCC lattice structures and hexagonal closest packed HCP.

All of the carbon atoms in diamond are connected to four other carbon atoms by strong chemical bonds, forming a tetrahedron structure throughout the crystal. Sp3 hybridization is a type of carbon atom hybridization. A three-dimensional network with a strong covalent bond is formed by a diamond.

Characteristics of Diamond:

Diamonds are a mineral form of pure carbon with a crystallised structure. They are precious gemstones that have many remarkable characteristics:

Structure:

Diamond has a crystal structure called diamond cubic. In the structure of a diamond, each carbon atom is attached to another four atoms. That is why the structure found is octahedral. It has a rigid structure.

Hardness and toughness:

Diamond is the hardest mineral of all. Diamonds are so hard that only diamonds can cut or scratch a diamond. Diamond is used in making cutting and scraping tools. Due to their rigid crystalline structure, they are easily breakable. That’s why they need skilled labourers or cutting and making things out of a diamond.

Conductivity:

Diamonds are known for the highest thermal conductivity. For the authentication of diamonds, thermal conductivity is considered.

Strength: 

Diamonds are said to be high compressive yields of strength. But they are non-compressible and have less compressible strength.

Rarity:

Diamonds are particularly rare. When compared to other gemstones, they are common precious stones. But there are different colours of diamonds present. The red colour diamond is so rare that there can be only twenty or thirty red diamonds present in the entire world.

Value:

Diamonds are just furnished forms of carbon. Diamonds have higher retail value than their resale cost. Hence, they are not considered a good option for investment. They have very high prices because of demand, but they are not valuable.

Clarity:

Clarity refers to the extent of imperfections present in a diamond. Diamonds are naturally produced, so they contain their marks and blemishes.  

Consumption:

About 80% of diamonds are used for industrial purposes. They are used in making tools, industrial equipment, machines, etc. They are also used in the pharmaceutical and medical industries. 

Colours:

Most commonly found diamonds are colourless, composed of pure carbon. However, different colours of diamonds are found. The colour of diamonds is due to the presence of impurities in them.

The colours are blue due to the presence of boron, brown and yellow due to nitrogen.

 Synthetic diamonds:

These diamonds are almost the same as natural diamonds but manufactured at the lab. They are artificial diamonds and are sold as gems in the market.

Carat:

Diamond is measured in carat. The cost of the diamonds depends on their cost. The one-carat diamond is of the best quality diamond. 

Conclusion

The diamond is a hard, crystallised mineral made up of carbon. It has an octahedral type of structure. They are found in many colours and shapes and sizes. They are used for industrial purposes, in medicines, in beauty products and the making of jewellery as gems. 

Based on occurrence, there are two types of carbon that are present natural and synthetic, and based on the purity of diamonds, they are of five types: Type la, Type lb, Type Iab, Type lla, Type llb.
