Diamonds

375 refers to 9 karat gold, which is composed of 37.5% gold and is commonly used in jewelry making. While it does contain gold, it is considered lower quality compared to higher karat gold such as 18 or 24 karat.

The letter "p" on the inside of a ring likely indicates the purity of the metal used to make the ring. It could stand for platinum, which is a precious metal commonly used in jewelry. Alternatively, it may denote the metal's plating or the manufacturer's brand.

There are several options for cleaning a diamond. The most highly recommended is to get it professionally cleaned at a jeweler, since s/he has the most appropriate material. Though it is almost impossible to harm the diamond itself with whatever you use, you can hurt the setting, or the metal that the diamond is encased in if we're dealing with a ring.

For this reason, it is discouraged to use boiling water, ammonia, toothpaste, or other abrasives that may damage the setting. Instead, you can use gentler cleaners such as dish detergent.

To get tough grime out of the cracks between your setting and the diamond, you should take it to a jeweler. They usually charge less than $20 for a cleaning, and you don't have to do it more than once or twice a year.

A diamond conducts heat, so a jeweler uses a probe that confirms that the stone you're evaluating indeed meets this criteria.

If you're interested in the quality of the metal, there are other tests that will give you this information.

Champagne diamonds are generally less expensive than traditional white diamonds, but their value can vary depending on factors like color intensity, clarity, and carat weight. They offer a unique and warm hue that some people find very appealing. The price of champagne diamonds can range from affordable to more expensive, depending on these factors.

To determine if a diamond is of SI2 quality, you would need to have it graded by a professional gemologist who examines the diamond under magnification for inclusions and blemishes. An SI2 diamond typically has noticeable inclusions that may be visible to the naked eye. It's important to have the diamond certified by a reputable gemological laboratory to verify its quality.

Diamonds are transparent, meaning they allow light to pass through them with little to no scattering. This optical property is one of the main reasons why diamonds are valued for their brilliance and sparkle.

The Kimberley Process helps prevent the trade of conflict diamonds by certifying that diamonds are sourced from legitimate mines. This certification process promotes ethical mining practices and transparency in the diamond industry. It also helps ensure that revenues from diamond sales do not fund conflict or human rights abuses.

Tenacity implies tenacious, the ability of some thing to be pulled apart.

Diamond is the hardest substance known: it does not pull apart. Rather, diamond cutters cleave diamonds using special tools and other diamonds.

Coal goes through several phases before it forms a diamond. First, it undergoes burial and becomes peat. Over millions of years of high pressure and heat, peat transforms into lignite, then into bituminous coal, and finally into anthracite coal. If the conditions are right, further heat and pressure can turn coal into graphite and eventually into diamond.

Chocolate, or brown, diamonds are made just like any other diamonds, when carbon is placed under extreme pressure. The brown color comes, in most cases of natural diamonds, seems to come from distortions or defects in the crystal matrix.

In synthetic diamonds, the brown color results from the presence of nickel and nitrogen atoms in the crystal matrix.

Brown diamonds are the most common colour of diamonds found.

'Chocolate' is the name of one shade of this brown colour. All diamonds are formed naturally far below the surface of the earth and erupted to the earth's surface through volcanic pipes.

Diamonds are typically formed deep within the Earth's mantle under high pressure and temperature conditions. They are brought closer to the surface through volcanic eruptions in a type of rock called kimberlite or lamproite. Diamonds can also be found in alluvial deposits, such as riverbeds and ocean floors, where they have been carried by erosion processes from the original sources.

According to Wikipedia, the DeBeers slogan...

"A young copywriter, Frances Gerety, coined the famous advertising line "A Diamond is Forever" in 1947, allegedly while she was dreaming."

The line may refer to the age of the diamond mineral, which takes, in alluvial mines, from 10,000 years to 1.8 million years to form, according to the KHI Web site.

As well, she may have wanted to infer that once the gift of a diamond is received, a promise of 'forever' is implied as a reference for the impending relationship.

The element is boron. Boron nitride exists in two forms, hexagonal and cubic, with the cubic form being as hard as diamond due to its strong covalent bonds. It is often used in high-temperature and high-friction applications as a lubricant or abrasive.

Diamonds are known for their exceptional hardness, making them resistant to scratching and wear. They also have a high refractive index, which gives them their characteristic brilliance and sparkle. Additionally, diamonds have strong thermal conductivity, making them useful in industrial applications such as cutting and drilling tools.

"fcly" is not a commonly recognized term in diamond color grading. The standard diamond color grading scale ranges from D (colorless) to Z (light yellow or brown). If you have more context or information, I can try to provide a more accurate answer.

No. For their size, diamonds are heavy and will not float.

200mg or 1/5th of a gram is one carat.

_____________Another Answer

The value of a one carat diamond depends on its cut, its colour and its clarity in addition to its carat weight, which you set at one carat.

A local jeweler can show you stones in your price range. You can expect to pay $2,000 or less - $8,000 or more for a good quality one carat diamond.

Diamond is a naturally occurring form of carbon, with its atoms arranged in a crystal structure called a diamond lattice. It is classified as a mineral due to its chemical composition and crystal structure. Diamond is the hardest known natural substance, making it valuable for industrial and gemstone purposes.

To date, the largest purple stone originated in Russia and was cut by Julius Klein Diamond Corporation. It's current ownership is unknown.

Internet Stones describes the stone as:

"The diamond is a fancy vivid purple, I-1 clarity, [a] heart-shaped stone weighing 7.34 carats..." The stone is named the Royal Purple Heart.

You can recognize a diamond by assessing its weight, cut, clarity, and color. A certified gemologist can use specialized tools and techniques to determine the authenticity and quality of a diamond. Additionally, diamonds are known for their sparkle, brilliance, and hardness compared to other gemstones.

A pure diamond is a diamond that is composed solely of carbon atoms arranged in a crystalline structure. It is colorless and is known for its exceptional hardness and brilliance. Pure diamonds are valued for their rarity and beauty.

A diamond turns into vapor when it is exposed to very high temperatures (above 3,500 degrees Celsius) in the presence of oxygen. At such extreme heat, the diamond undergoes combustion and reacts with oxygen to form carbon dioxide gas.

Diamond is a naturally occurring mineral composed of carbon atoms arranged in a crystal structure. It is the hardest known material with a Mohs hardness of 10, and it has a high refractive index, making it sparkle and have a lustrous appearance. Diamonds are commonly used in jewelry but also have industrial applications due to their hardness and thermal conductivity.
