Diamonds

Diamond is composed of carbon atoms arranged in a tetrahedral structure, making it a covalent network solid. Most metals, on the other hand, have metallic bonding where electrons are free to move throughout the material. This difference in bonding accounts for the distinct properties of diamond, such as its hardness and transparency, compared to most metals.

Your answer depends on the quality of diamonds you want to purchase.

Gem-quality diamonds are weighed in carats. A top gem-quality, one-carat diamond today at Blue Nile will cost you US$23,672. One kilo equals 5,000 carats. Can you do the math?

If you want to purchase a kilo of industrial diamonds, and if you buy in bulk on a regular basis, you may be able to purchase a kilo for about the price of a latte grande.

Diamonds have an extremely high index of refraction, the property that makes a spoon in a cup of water look bent at the point where the water meets the air. It causes light that enters the diamond come back out at different angles, and some of the light reflects within the diamond for a while before coming back out (it's the same phenomenon as when you look at the surface of the water in a fish tank from a very shallow angle below the surface and it looks like a mirror, except to a greater angle).

Light traveling from a less dense medium, like air, into a more dense medium, like a diamond, is bent toward the normal, the imaginary line perpendicular to the surface where the two media meet at the point where the light enters. Light going from a more dense medium to a less dense medium is bent away from the normal.

Also, different colors (wavelengths) are bent different amounts, which is how a prism works and why sunlight reflecting off the insides of raindrops creates a rainbow.

The volume of a diamond cannot be determined solely by its weight. The volume would depend on the specific cut, dimensions, and density of the diamond.

According to metric conversion calculator on metrics conversions dot org: 42.52 ct weighs 0.299969 ounces.


(The carat weight you quote is the exact weight of the Hope Diamond.)

The 3,106 carat stone you reference is the rough diamond stone found in Africa, from which The Cullinan Diamonds were 'chipped'. That many carats weights about one and a third pounds.

You can see in the photo, link below, of the largest of these 'chips' what a 503+ carat, cut and polished stone looks like in the hands of the jeweler.

This means that the 3,000 plus carat stone -- the uncut, rough stone, was about six times the size of the stone in the top photo.

An archive photo of the raw stone is visible further down the page. The stone appears to fill a man's hand.


Some rough diamonds are shaped like two pyramids, joined at the base. This stone, however, appears to be shaped asymmetrically.

Take the stone to a reputable gemologist and ask for a description of its cut, colour, carat weight and clarity.

Then ask a jeweler how much s/he would charge you for a comparable stone. This may give you an indication of about how much the stone is worth.

The 4 C's of diamond grading include the carat weight, cut, color and clarity. When one decides to buy a 4 C's diamond, one should consider the cut of the diamond, which is how the diamond appears in terms of proportions and brightness.

A jeweler's loupe, which is a special magnifying tool, is commonly used to examine diamonds closely for their clarity, color, and any imperfections. Additionally, tools like a diamond tester can be used to verify the authenticity of the diamond and to determine if it is a real diamond or a simulant.

Yes, man-made diamonds can pass the thermal probe test because they have similar thermal conductivity properties as natural diamonds. The thermal probe test measures how quickly heat is conducted through a diamond, and both natural and man-made diamonds should have similar results when subjected to this test.

The cut clarity colour is used when making, producing, and selling, diamonds. The cost and importance of the diamond depends on all three, the cut, clarity, and colour, of each and every diamond.

Diamonds are formed into crystals with a perfect octahedral crystal habit. Hardness is associated "...with the crystal growth form, which is single-stage..."

"The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material."

All quotes according to Wikipedia research.

Diamonds are formed by tremendous pressure under the earth's surface which causes carbon to crystallize. When this happens in the presence of certain trace elements, a distortion of the normal crystallization process can occur and result in the beautiful colors seen in some rare and expensive diamonds.

Lab created diamonds are made using two main methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). In the HPHT method, a small diamond seed is exposed to high pressure and temperature, causing carbon atoms to bond and form a diamond crystal. In the CVD method, a diamond seed is placed in a chamber with a mixture of gases, and a chemical reaction occurs to create layers of carbon atoms that gradually form a diamond crystal.

Diamonds are found in the earth in the soil, together with stones of trace minerals indicating that the volcanic pipe that erupted the contents to the surface may contain diamond stones.

Diamonds are composed of carbon.

Diamonds are allotropes of carbon. Trace amounts of other minerals may be included, and generally, these trace amounts give a diamond colour. Most commonly, nitrogen is included giving a diamond a yellow cast.

Yes, diamonds are formed deep within the Earth under conditions of high pressure and temperature. The immense pressure exerted on carbon atoms causes them to bond together in a crystal lattice structure, forming diamonds over millions of years.

Diamond is harder than glass, so a diamond will 'mark' glass.

Glass-cutting takes place when the worker uses a diamond-tipped tool to mark the glass along the cut line, then applies pressure to the glass on both sides of the mark.

Glass-cutting tools are tipped with industrial diamonds, which are 80% of all diamonds mined.

Diamond is harder than gold because of its crystal structure. Diamond consists of carbon atoms arranged in a rigid, three-dimensional lattice structure which makes it extremely resistant to scratching or deformation. Gold, on the other hand, has a more loosely packed atomic structure which is why it is much softer and more malleable compared to diamond.

Chocolate diamonds are not made in a traditional sense like lab-grown diamonds. They are natural brown diamonds that undergo a specific treatment process to enhance their color, making them suitable for use in jewelry. This process involves high-pressure, high-temperature treatments to alter the diamond's color from a pale brown to a rich chocolate hue.

Diamond is abrasive because it is one of the hardest known natural materials, ranking a 10 on the Mohs scale of mineral hardness. Its hardness allows it to effectively cut and scratch other materials, making it ideal for use as an abrasive in cutting, grinding, and polishing applications.
