Diamond: A gem mineral with properties for industrial use

Diamonds are uncommon carbon minerals. Each carbon atom in a diamond is surrounded by four others and linked by covalent bonds, the strongest form of chemical connection. This basic, consistent, tightly bonded structure creates a durable and adaptable material.

Gemstone diamond

The most common gemstone is diamond. Diamond gemstones are the most expensive gemstone. Diamond's attractiveness is partly due to how it responds to light. Diamonds are durable, fashionable, custom-made, and aggressively marketed. April's birthstone is a diamond. Diamonds have the greatest non-metallic luster, adamantine. Their great luster reflects a lot of light. This makes diamonds "sparkle." When a diamond is cut into a gem, its facet angles are designed to reflect as much light as possible.


Ideal diamonds are fracture- and inclusion-free (particles of foreign material within the gem). These blemish the jewel and block light. Large numerals, dark hues, conspicuous placements, or sizes impair a cut gem's look and value. They weaken the stone.

High-quality diamonds

Color, cut, clarity, and carat weight define a diamond's gem quality. Gemological Institute of America created "The 4Cs of Diamond Quality" in the 1950s.


Most gem-quality diamonds are colorless, yellow, brown, or grey. Colorless diamonds are the most valuable. Most expensive ones. Another diamond gemstone is popular. There are red, pink, yellow, orange, purple, blue, green, and brown colored diamonds. Color intensity, purity, and quality determine colored diamonds' value. "Fancy-color diamonds" have a vibrant, bright hue. One in 10,000 diamonds is "fancy." Rareness makes fancy-color diamonds precious. Some have sold for over $1 million per carat. They're among the world's most precious diamonds.


The cut is what defines a diamond's look. Face-up look, brightness, scintillation, pattern, and fire are determined by facet angles, design proportions, and polishing quality. Ideal stones are highly reflective and fire-emitting. Equal-sized and shaped facets correspond. Each facet's edges match its neighbors exactly.

Carat: 1/5th of a gram or 1/142nd of an ounce. Smaller, equal-quality diamonds cost less per carat. Small stones are plentiful, while huge ones are unusual.

Diamond Gemstones uses

Most diamonds are used as abrasives. Diamonds have different uses.

·         Diamond windows use thin membranes. They cover laser, x-ray, and vacuum chamber holes. They're clear, sturdy, and heat- and abrasion-resistant.

·         Diamond speaker domes improve sound quality. Diamond is a strong material. Thus a thin dome may vibrate quickly without deforming and affecting sound quality.

·         Heat sinks absorb or transfer heat. Diamond is the best thermal conductor. It removes heat from high-performance microelectronics.

·         Microdevices require low-friction micro bearings. Diamonds are utilized when exceptional abrasion resistance, durability, and dependability are essential.

·         Thin diamond coatings provide wear-resistant components. Carbon vapor is used to deposit diamonds on wear-prone objects.
