Diamonds

Chocolate diamonds from this source can be assured to be of the chocolate colour as advertised.

A gemologist can help you understand if and/or how any diamond has been treated to enhance its colour, or where the diamond was formed, either underground or in a lab.

The design of playing cards varies among different regions and manufacturers. In some designs, the King of Diamonds is depicted facing sideways as part of the card's intricate and unique artwork. It has no specific symbolic meaning and is simply a stylistic choice in card design.

No, diamonds are not found in nature already cut. They are formed deep within the Earth's mantle and are extracted as rough stones, which then need to be cut and polished to reveal their brilliance and beauty.

Diamonds are one of many different forms that the element carbon can take, and it is much easier for carbon to form other substances, particularly coal or graphite, rather than diamond, which requires extreme pressure and blistering high heat to form.

"Natts" is not a standard term associated with diamonds. It is possible that there may have been a typo, mispronunciation, or confusion with another term. Can you provide more context or clarify your question further?

Diamond 'connoisseurs' prefer Type IIa diamonds, which are found in India and in South Africa.

Type IIa diamonds are the purest form of diamond, containing zero impurities. From Wikipedia:

"Type IIa diamonds make up 1-2% of all natural diamonds (1.8% of gem diamonds). These diamonds are almost or entirely devoid of impurities, and consequently are usually colourless and have the highest thermal conductivity."

Harry Winston purchased the Hope Diamond as part of a collection.

According to Wikipedia:

"When Ms. McLean died in 1947, she bequeathed the diamond to her grandchildren through a will which insisted that her former property would remain in the custody of trustees until the eldest child had reached 25 years of age. This requirement would have prevented any sale for the next two decades. However, the trustees gained permission to sell her jewels to settle her debts, and in 1949 sold them to New York diamond merchant Harry Winston. He purchased McLean's 'entire jewelry collection'."

Diamonds have been part of human history for about 6,000 years, before humans began keeping written records of alluvial diamonds. Identifying the biggest alluvial diamond ever found, then, is not possible.

Probably, the first diamond found and admired was an alluvial diamond. You can read more, below.

The value of a 1948 diamond starfire ring would depend on factors such as the quality and size of the diamonds, the metal used, the condition of the ring, and any historical significance it may hold. It is recommended to have the ring appraised by a professional jeweler or an antique expert for an accurate valuation.

If a diamond reflects light, it means that it has good optical properties and is likely well-cut. This can enhance its brilliance and sparkle, making it more visually appealing. Diamond cut is one of the 4Cs of diamond grading, and a well-cut diamond can maximize its beauty and value.

The most expensive diamond color is generally considered to be a vivid and pure shade of pink, followed by blue and green. These fancy colored diamonds are rare and highly sought after, commanding premium prices in the market.

No, diamonds are not found in sea shells. Diamonds are typically formed in the Earth's mantle and are brought to the surface through volcanic activity, while sea shells are formed from the calcium carbonate shells of marine organisms.

The lowest grade for diamond clarity is I3 in the GIA (Gemological Institute of America) clarity grading scale. Diamonds in the I3 category have very noticeable inclusions that may affect both the beauty and durability of the stone.

The highest clarity grade is F - Flawless, or IF - Internally Flawless.

No, diamonds are not made from volcanoes. Diamonds are formed deep within the Earth's mantle under high pressure and temperature, typically found in kimberlite pipes that bring them to the surface through volcanic eruptions. Volcanoes can bring diamonds closer to the surface, but they are not the source of their formation.

'Value' implies a transaction for money.

The largest and most spectacular diamonds in the world generally do not change hands for money; they change hands as gifts or often, spoils of war.

The highest quality, gem-quality diamonds have been found in South Africa and Zaire. These include the Cullinan Diamond, and the Millenium Star, respectively. Other spectacular diamonds have been found in India.

You can read more about these named diamonds, below.

The largest diamond ever found is the Cullinan Diamond, which weighed more than 3,000 carats. It filled a grown-man's palm. It has been cut down into several 'minor' diamonds, all in the possession of the British Crown Jewels and the Royal Family.

Your earrings may need cleaning.

You can clean diamonds by soaking them in warm, soapy water to loosen the dirt, then you may brush them carefully to remove the dirt, taking care not to loosen the diamond in the setting, and rinsing them under running water.

Alternatively, you can blast the jewelery with forceful steam to clean them.

NB: Harsh chemicals may affect the metal in the setting.

Your answer depends on what you consider 'fine' or 'finest': colour, clarity, carat weight or cut or which of these in what kind of combination.

The diamond would be either D colour on the colourless scale, or a Fancy Intense Vivid colour if a coloured stone; internally it would be Flawless; it would have the heaviest carat weight possible for the quality and style of the cut.

Your choice.

A 625 carat diamond refers to a diamond that weighs 625 carats. Carat is a unit of measurement for gemstones, with one carat equal to 200 milligrams. A diamond of this size would be considered extremely rare and valuable.

Yes, when sunlight passes through a real diamond, it can create a blue reflection known as "blue light dispersion". This phenomenon is caused by the diamond's ability to refract light into its spectral colors, with blue being one of the prominent hues.

Some diamonds can exhibit fluorescence when exposed to ultraviolet light, often appearing blue or white. This phenomenon is not always present in all diamonds and varies depending on the type and quality of the stone.

According to Wikipedia:

"The Regent Diamond ... is on display in the Louvre. In 1698, a slave found the 410 carat (82 g) uncut diamond in a Golkonda mine, more specifically Paritala-Kollur Mine in the state of Andhra Pradesh, India and concealed it inside of a large wound in his leg."

You can read more about this stone, below, including the events surrounding its reduction to 141 carats.

"Circulation" in the world of large diamonds is probably a shadowy place, with not much information being available about 'biggest', and especially 'biggest blue' diamond.

However, in 2008, the 35.56 carat cushion-shaped gem, The Wittelsbach Diamond, became available at auction and fetched 16.4 million British pounds. You can read more about it, below.
