Diamonds

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."

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.

Diamonds are real because they are naturally occurring gemstones formed deep within the Earth's crust under high pressure and temperature. They are composed of carbon atoms arranged in a crystal lattice structure, giving them their unique properties such as hardness and brilliance. Additionally, diamonds must also meet specific criteria to be considered gem-quality, including clarity, color, cut, and carat weight.

The fracture of diamond is "conchoidal or shell-like," according to Wikipedia.

Industrial diamonds are more easily broken apart based on the nature of the crystal's fracture lines. Gem-quality diamonds are more generally immune to being broken apart, because they are cut, polished and set in ways to minimize exposure to the natural fracture lines in the crystal.

When a diamond is crushed, it typically retains its original color since its color comes from impurities or structural defects in the crystal lattice, which remain intact even when the diamond is broken down into smaller pieces. Therefore, the crushed diamond would appear the same color as the original diamond.

Moissanite is a lab-created gemstone with a lower cost and higher brilliance than diamonds. While diamonds are natural gems that are extremely hard and durable, moissanite is also a durable gem but ranks lower on the Mohs scale of hardness. In terms of brilliance and sparkle, moissanite tends to exhibit more fiery and colorful flashes compared to diamonds. Ultimately, the choice between moissanite and diamond comes down to personal preference and budget.

The formula for diamond is simple, it is composed of carbon atoms arranged in a face-centered cubic crystal structure. Each carbon atom forms four strong covalent bonds with other carbon atoms in a tetrahedral arrangement, resulting in the exceptional hardness and unique physical properties of diamond.

Black diamonds, also known as carbonado, are formed differently from traditional diamonds. They are believed to have originated from outer space, potentially from supernova explosions or graphite-rich asteroids colliding with Earth. Due to their unique structure and high abundance of inclusions, their formation process is not fully understood.

Gems are mined from the earth in various methods around the planet. These gems are separated from the unwanted material at the mine. The unrefined gems will be then sorted for size and quality, larger stones will be separated out to be treated specially in efforts to maximise value. Stones that are deemed to be of a high enough quality will go on to the gem smith where they will be cut to size according to the type of cut needed. Some of these cutting steps are, planning, and cleaving or sawing, bruting, and polishing.
