Diamonds

The 'most shiniest' diamond is one that is kept clean, and exposed to light that compliments its cut.

Yes, a black diamond is a real diamond.

According to Wikipedia:

"Carbonado, commonly known as the 'Black Diamond', is a natural polycrystalline diamond found in alluvial deposits in the Central African Republic and Brazil. Its natural colour is black or dark grey, and it is more porous than other diamonds."

Your answer depends on your definitions of 'biggest' and 'worth'.

Any diamond is valued by its cut, its colour, its clarity and its carat weight. Large stones tend to be priced in the multi-millions of (US) dollars. The most notable diamonds in the world changed hands based on gifts or spoils of war, and are therefore priceless: no money changed hands.

Anything is only worth what someone will pay you for it.

Diamond is heavier and more dense than any other mineral, so gravity operates on the ring and pulls the stone toward the earth.

You may want to ask a jeweler to make the ring slightly smaller, so that it doesn't turn so easily.

The Cullinan Diamond is considered important because it is the largest gem-quality diamond ever found, weighing over 3,100 carats. It has historical significance as it was discovered in South Africa in 1905 and gifted to King Edward VII. The diamond was cut into several smaller stones, some of which are part of the British Crown Jewels.

Some flawed diamonds could be called translucent: generally these diamonds are given an industrial use.

Diamonds are valuable for their hardness and ability to be used in various industries, such as in jewelry, cutting tools, and industrial applications. They also have unique optical properties that make them useful in scientific research and high-tech applications, such as in laser technology. Additionally, diamonds have cultural and symbolic significance in many societies.

According to Wikipedia's List of diamonds:

"[The] Koh-i-Noor [weighs] 105.6 [carats], [is] colorless [and is described as] a 105.6 carat (21.6 g) white of Indian origin, with a long and turbulent history and a good deal of legend surrounding it. After belonging to various Mughal and Persian rulers, it was gifted away by the Maharaja Duleep Singh of Lahore and was presented to Queen Victoria during the British Raj, and is now part of the Crown of Queen Elizabeth the Queen Mother."

Natural diamonds are not blue in color. Blue diamonds are formed when the presence of boron impurities during their formation process causes them to absorb certain wavelengths of light, resulting in a blue hue.

Diamonds are not typically used as reflectors because they have a high refractive index, which causes light to be refracted rather than reflected. Materials with lower refractive indices, such as metals or mirrors, are more commonly used as reflectors.

Diamonds were first discovered in India more than 2,000 years ago, with the exact date not known. They were initially prized for their unique properties, including their brilliance and hardness. Today, diamonds are found in various regions around the world.

Some of the highest quality diamonds are found in mines located in countries like Russia, Botswana, Canada, and some regions of Australia. These areas are known to produce diamonds with exceptional clarity, color, and size due to the geologic conditions present there.

Yes, if they are natural diamonds.

Diamonds can be treated or enhanced to 'bring out' a colour, so a faint pink diamond could be treated to enhance the colour and become a more intense pink.

Enhanced diamonds are of a lesser value than naturally coloured diamonds.

Today, most natural pink diamonds are produced from the Argyle mines in Australia, and are pink based on "...low levels of nitrogen impurities, their colour resulting instead from structural defects of the crystal lattice," according to Wikipedia.

Visually, there are trace minerals that indicate a volcanic pipe, which might contain diamonds. The trace minerals include kimberlite, and only one kimberlite pipe in 200 yields gem-quality diamonds.

The largest known diamond is the Cullinan diamond, which was discovered in South Africa in 1905. It weighed 3,106 carats in its rough form and produced several large diamonds, the largest of which is the Cullinan I, also known as the Great Star of Africa, which is 530.2 carats.

Diamonds are formed deep within the Earth's mantle under high pressure and temperature conditions. They are brought to the surface through volcanic eruptions that originate from deep within the Earth's mantle. Once on the surface, they are mined by humans for various purposes, including jewelry and industrial uses.

Given a light source and movement, a diamond will sparkle in air or under water.

I would expect the effect to be greater in air than in water though, because the density difference between diamond and surroundings are that much greater.

The Hope probably originated in Golconda, India, with an undocumented provenance until it was sold by Jean Baptiste Tavernier to French Royalty in the 1600s.

According to Wikipedia:

"Though [Tavernier] is best known for the discovery and sale of the 118-carat (24 g) blue diamond that he subsequently sold to Louis XIV of France, was stolen in 1792 and re-emerged in London as The Hope Diamond..."

The Crater of Diamonds is located in Arkansas near the town of Murfreesboro. It is a state park and is open to the public daily for a small fee. Everything that you find is yours to keep and yes, they are real diamonds.

The largest uncut diamond ever found is the Cullinan diamond, weighing 3,106 carats or about 1.37 pounds. It was discovered in South Africa in 1905 and was eventually cut into several smaller diamonds, the largest of which is the Great Star of Africa, weighing 530 carats.

Yes, lasers can be used to cut diamonds in jewelry crafting and industrial processes. The high intensity of laser beams can precisely cut through the hard surface of diamonds without damaging the gem's clarity and quality. This method allows for more intricate and complex cuts to be made on the diamond.

Diamond is the hardest known natural material on Earth, scoring a 10 out of 10 on the Mohs scale of mineral hardness.

A solo diamond setting is called a solitaire.

By name, Craters of Diamonds State Park is located in USA, in Arkansas.

All diamonds are exploded to the earth's surface from volcanic pipes, which when mined turn into craters. You can see these craters in Africa, Canada, Russia, Brazil, India and Australia.
