Diamonds

There's no notable diamond named the Ocean Diamond, but the Heart of the Ocean Diamond -- a fictional stone from Cameron's Titanic.

According to RingEnvy -- "The one used for the film was an enormous 56-carat [stone], giving it a length of almost two inches. A cluster of smaller, colorless stones and diamonds surrounds the central gemstone as well."

Diamonds are formed deep within the Earth's mantle under high pressure and temperature conditions. They are brought to the Earth's surface through volcanic eruptions in rock formations known as kimberlite or lamproite pipes. Diamonds can also be found in alluvial deposits, where they have been eroded from these primary sources and carried by rivers and streams.

The answer depends on comparing two specific items: a moon rock and a diamond.

Comparatively, there are many answers to your question. Each has to do with the composition of each item.

For example, diamonds are valued by their cut, clarity, colour and carat weight. Moon rocks are valued another way.

You can buy a 'moon rock' today for about US$45; you might find a tiny diamond for sale at that price, but more likely, you'd pay more for a diamond than for a moon rock if each item were the 'same size'.

The two measurements you give are not related, essentially.

The MM measurement could be the diameter of a brilliant cut diamond, or one measurement of another shape. The carat weight you give is a weight measurement of gemstones.

One way to spot a fake diamond is to check the diamond's clarity and color - fake diamonds often have imperfections and lack the sparkle of real diamonds. You can also use a loupe to look for any imperfections that are typical of lab-created or synthetic diamonds. Finally, taking the diamond to a professional appraiser or jeweler for testing can confirm its authenticity.

Diamonds can appear foggy or cloudy due to the presence of inclusions or surface blemishes that affect their clarity. Factors such as poor cut, improper polishing, or dirt buildup can also contribute to a diamond looking foggy. In well-cut and well-maintained diamonds, this foggy appearance is less likely to occur.

Any natural diamond, regardless of its colour, is as old as the earth itself.

The Hope Diamond is basically a blue diamond.

The Hope Diamond is one of the largest blue diamonds in the world, measuring about 1 inch in length (25.6 mm), 7/8 inch (22.8 mm) in width, and 4/8 inch (12 mm) in depth. It weighs 45.52 carats and is considered to be priceless due to its unique color and history.

The Kohinoor diamond is currently part of the British Crown Jewels and is housed within the Tower of London. It was presented to Queen Victoria in 1851 and has remained in the possession of the British monarchy since then.

The Jubilee Diamond was discovered in South Africa in 1895. The diamond was cut from a 650.80-carat rough diamond and is renowned for its exceptional clarity and color. It was later acquired by famous jeweler Harry Winston.

Screen clarity can be affected by factors such as resolution, pixel density, display technology, brightness, contrast ratio, and viewing angle. Higher resolution and pixel density typically result in clearer images, while factors like brightness and contrast ratio impact the overall visibility of content on the screen. Viewing angle determines how well the screen can be seen from different perspectives.

It would depend on the carat weight, the colour, the cut and the clarity of the stones to achieve this dollar amount.

There have been a few auction sales where single diamonds have been sold for US$15-30 million. The reason these stones sell for so much money is because they are so rare.

If, for example, you could find more stones of this quality, a single stone being worth $30 million, you'd need more than 30,000 such stones.

Real diamonds reflect light in a way that produces a multitude of colors, known as diamond fire, but they do not actually shine in different colors like a rainbow. The sparkle and brilliance of a diamond come from its cut, clarity, and the way it interacts with light, known as dispersion.

The Hope Diamond is one of the most famous diamonds due to its large size (45.52 carats), rare deep blue color, and storied history of being associated with curses and mysterious events. Its unique characteristics and rich backstory have captured the public's imagination for centuries, contributing to its enduring fame.

Diamonds were discovered in Canada in the early 1990s when indicator minerals containing diamond were detected in the soil. This led to the discovery of diamond-rich kimberlite pipes in the Northwest Territories, where the first diamond mine, Ekati, opened in 1998. Since then, several other diamond mines have been developed in Canada.

There are a number of different ways to see if a diamond is real. The quickest and easier is the fog test: a real diamond will disperse the heat from your breath immediately, the setting: such as 10k, 14k or 18k stamps inside the setting, anything with a C.Z (cubic zirconia) usually indicates that the diamond is not real, a jewelers loupe and also if it has rainbow reflections if you look at it from the top. You can also take it to a jeweler and get it evaluated.

sounds to me like you're thinking of the heart of the ocean

Generally, yes, so long as the diamond is a gemstone and not an industrial diamond.

Because most gem diamonds are smaller than for example, a lens, it's a good idea to simply look for light through the stone. You might not be successful trying to read text through a diamond.

No, i don't think so because you have to know that diamonds were first made from carbon.

Diamonds conduct electricity, and your local jeweler probably has a diamond tester that uses this characteristic to tell real stones from the fakes. You can take your black diamond in and ask that the stone be tested. Edit From Siddharth Nayak: Also, if a diamond tester tries to get payed for his/her services, there is a quicker, faster, and free way: simply hold the diamond out in the sun, and if it gets hot, then it is glass, if it stays normal temperature, it is a diamond...but then again, it might be simply coated with diamond and internally glass... -Siddharth Nayak

Like any gemstone, it's best to do your research before buying. Only buy from a reputable dealer (regardless of the brand or name stuck to it).

So not confuse Crown of Light with diamond cut. Crown of Light is a registered brand name. They are selling a cut called the Crown of light cut. There have been a number of complaints made about the quality and pricing of the diamonds on some consumer sites. You really need to do your research and judge for yourself as to the quality and price.

The diamonds themselves come from a company called the Namibian Diamond Trading Company, which is supposed to be conflict free. If you do a bit of digging you will find out the diamonds are actually from De Beers, Namibian Diamond Trading is part of the De Beers' group.

Again, if you like what you see, and like the price. Go ahead and buy it. If you don't, there is plenty of competition. Its a very personal choice.
