Diamonds

Pure Ascorbic Acid which is generally used for food supplements and in foods is generally NOT from a natural source. It is synthetised by a chemical reaction, sometimes also by using genetically modified organisms.

When it comes out of the ground, a diamond can be a dull, lifeless piece of stone. The brilliance of a gem-quality diamond -- only 25% of diamonds mined -- comes from the cutting and polishing processes that bounces the maximum amount of light around inside the stone before refracting it out of the top of the diamond back to your eye.

Different diamonds have different color intensities like yellows and blues and the rarest of all, the pinks, but still the brilliance comes from the cut. If you ever want an opportunity to have your breath taken away for a few seconds, try to see the Crown Jewels in London for a spectacular show of diamond fire. They are very 'bright'.

Adamantine to waxy luster are the words used to describe the luster of diamonds.

According to Wikipedia:

"Adamantine minerals possess a superlative lustre, which is most notably seen in diamond. Such minerals are transparent or translucent, and have a high refractive index (of 1.9 or more)."

Luster is the clarity and refractivity of an individual stone. Not all diamonds are created equal. Flawless diamonds are extremely rare and can be prohibitively expensive for most of us. In jewelry, generally diamonds evaluated as those containing VVSI (very very slightly included) to SI2 (two slight inclusions), are more affordable. SI2 is generally the lowest grade for good gems. Inclusions can be any imperfection.

The luster is its refractiveness. Its ability to bounce back available light from inside the stone. This can be affected by the color, cut or clarity. Only 20% of all diamonds mined are gem-stone quality.

Yes, sapphires are one of the hardest gemstones, scoring a 9 on the Mohs scale. While they can scratch glass, they are not typically used for cutting it because the hardness of glass falls between 5 and 6 on the Mohs scale, making it difficult to achieve a clean cut.

A lab created diamond is a real diamond in all ways. It is chemically, physically, optically and molecularly identical to a mined diamond. There are only a couple of companies that can grow diamonds, and are still expensive (a few thousand dollars per carat). These should not be confused with simulants. Simulants may look like a diamond, but do not possess the same properties as a diamond. These include cubic zirconia and moissanite and are available for a hundred dollars or less per carat.

The comparison can be made in terms of their fragility, as both control and question glass may be delicate or easily breakable. Glass that cannot be pieced together implies a level of fragility similar to the control and question glass.

It is impossible to determine who found the first diamond, but until the Dutch discovered them in South Africa, India was the only known source.

It is possible that the first human picked up a diamond more than 6,000 years ago, probably in India.

Diamonds are most commonly found in Africa due to the presence of ancient volcanic activity that brought diamonds closer to the Earth's surface where they could be mined. Additionally, Africa has a long history of diamond mining, with countries like Botswana, South Africa, and Angola having significant diamond deposits. Political stability and the presence of well-established diamond mining operations also contribute to Africa's status as a major diamond producer.

"Diamonds don't burn, unless you can find a heat source equal to 3820 degrees Kelvin (6416F, 3546C), then diamonds simply melt."

actually diamonds do burn at about 800*C

A gem-stone quality diamond is valued by its cut, clarity, carat weight and colour.

Diamond is one allotrope carbon of where the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic. Diamond is an optically isotropic crystal that is transparent to opaque.

Seventy-five percent or more of all diamonds mined are used by industry, because of the hardness of diamond.

Diamonds are one of the hardest naturally occurring substances, scoring a 10 on the Mohs scale of mineral hardness. This means that diamonds are extremely resistant to scratching and abrasion, making them ideal for use in jewelry and industrial applications where durability is important.

The Science Olympiad typically awards medals or trophies based on performance at regional, state, and national competitions. These medals are not necessarily diamond, silver, or gold; they are usually made of metal and have the Science Olympiad logo engraved on them. The specific award categories and designs may vary by competition level and region.

A diamond consists of covalent bonds between carbon atoms, where each carbon atom shares electrons with four neighboring carbon atoms to form a strong, three-dimensional network. This results in the diamond's hardness and durability.

One carat is equal to 200 milligrams, or in other words, a 5-carat stone weighs 1 gram.

Zircon is a colorful gem with high refraction and fire that's often confused with cubic zirconia. Well known for its flashes of multicolored light. It is sometimes looked upon as a cheap Diamond simulant, but in actuality it can be a valuable gem. Its color diversity is caused by traces of certain impurities, some of which are radioactive.

On the Mohs scale of relative mineral hardness, diamond is the hardest at 10.

Well... if you want to make one i saw this one time... i cant remember where... but put a piece of all natural coal in the microwave.. the microwave HAS to be out side away from civilazation! and put it in on high for about 10 min.. and it will turn in to a dimond on the inside! but you have to get something to crack the coal open after you microwave it so you can get the dimond!! good luck! i did it before! your gonna need safety goggles and you might want to stand back... alot!

Synthetic single crystal diamond has an identical physical structure to that of natural single crystal diamond. The basic diamond atomic structure, described by its unit cell can be pictured as a face-centred cube with a carbon atom in the middle of each face and four more atoms arranged diagonally opposite each other in pairs, with the upper plane offset at a right angle to the lower plane. Unlike graphite, the individual planes are not flat but corrugated. In diamond, each carbon atom is connected to four other carbon atoms by covalent bonds. In the simplest case, these four atoms form a perfect tetrahedron. Due to covalent bonding between the atoms there are no free electrons and synthetic diamond is normally not electrically conducting. In the case for synthetic diamond, one or more of the carbon atoms might be replaced (or substituted) with nitrogen atoms, giving the diamond a yellow colour.

The Hope Diamond weighs 45.52 carats. One carat is equal to 200 milligrams, so in other words, the Hope Diamond weighs 9.104 grams.

TWD Diamond is a digital currency used in blockchain-based projects and games within The Walking Dead universe. It can be earned, bought, and used for various in-game activities and purchases.

In chemistry, an allotropism is the ability of an element to exist in more than one physical form without a change of state.

The cost of carbon in diamond form varies depending on the size, quality, and source of the diamond. Generally, diamonds are priced based on the carat weight, cut, clarity, and color. High-quality diamonds can range from a few thousand dollars to millions of dollars per carat.

The hardest naturally occurring substance is diamond. Diamond is made of carbon atoms arranged in a strong crystal structure, making it extremely durable and resistant to scratching or breaking.
