The colors of diamonds under the microscope – unVraiBijou

Categories: Blog

For you and for me, a diamond is white, or at least colorless, and it sparkles with a thousand lights.

In fact, in most cases, a diamond absorbs all wavelengths of light and reflects them (like what on a pretty blonde with a diamond, there is something that reflects), that’s why that no color can be distinguished. Yes, but…

Diamonds in red, pink, green, yellow …

As usual when something is simple, there are exceptions, and diamonds are no exception (it’s like gold which can be yellow, white or pink). So in the exceptions, we obviously find colored diamonds.

To change a little and make your friends drool, a diamond ring (beautiful rings at Private Diamond Club) is still the must, and why not with a colored diamond?

The yellow diamond

Its yellow color comes from the fact that nitrogen atoms are present in its structure. The yellow diamond is the most common of the colored diamonds. It is therefore the cheapest compared to blue or pink, but I will not venture to give prices because they depend a lot on the color, the intensity, the purity.

When its yellow is very marked, it is then assigned the color “daffodil”. The yellow diamond in 4 color levels from lightest to darkest: Fancy Light Yellow, Fancy Yellow, Fancy Intense Yellow and Fancy Vivid Yellow

Among the famous yellow diamonds, the Tiffany Yellow serves as a support for this bird.

The blue diamond

The blue diamond is the exception, its great rarity even makes it much more expensive than the white diamond. This time, the color is due to the presence of Boron in its structure.
This configuration is so rare that it is currently only found in three mines, one in Australia, one in South Africa, and the last in India.

As for yellow, there are multiple shades of blue diamonds

Note that the chemical composition of sapphires and blue diamonds is very different, so do not try to pass on your sapphire while trying to surround a jeweler, he will spot you immediately.

On the price side, prices are soaring, The Winston blue has reached nearly $ 25 million.
Among the stars of blue diamonds, we find the famous crown diamond or Hope diamond that we told you about previously.

The green diamond

Still a rarity than the green diamond, long confused with the emerald in some of its shades. The film “The Hunt for the Green Diamond” has given this diamond some letter of celebrity.

It is a natural irradiation in earth due to the exposure to the radiation of uranium which causes the color of these diamonds.

It should be noted that the polishing of green diamonds is very complex, because if the stone is too heated during this polishing, it risks losing its natural green color. The practice is therefore extremely long and meticulous.

The most famous and the biggest known is the diamond dresden green (it takes its name from the city where it is exhibited).

The pink diamond

Once again, we remain in the very great scarcity.
Where does this diamond get its color? Well we don’t know! It is assumed that it is the temperature and pressure conditions linked to its environment which causes this tint by generating its absorption of certain wavelengths. To date, the mine where 90% of these diamonds are found is located in Australia.

Another particularity of pink diamonds is their hardness, so they take a particularly long time to polish (3 to 4 times more than a classic diamond).
Among the famous pink diamonds is the “Pink Star”, discovered in South Africa.

Then ? What color for your diamond ring?

Let’s be reasonable, given the current prices, the colorless diamond is probably the best way to go. Even if the price range remains wide, for example from 315 euros up to 54,000 euros at Private Diamond Club.

And never forget what Marilyn said, diamonds are best girl’s friend!
