The Argyle Pink Diamonds: A Shining Gemstone That Is Very Rare

Argyle pink diamonds are rare gems that have a unique color that is only found in a single mine in the world. It is one of the most stable hues that can exist for pink diamonds. Argyles are not as easily distinguished from other shades of pink as other rare varieties of pink diamonds. To be called an argyle, the pink diamond needs to show two intersecting patterns with inclusions or transparency. The pattern inside the colored area has to show three or more vertical layers of different colors, making it appear like a lace work. Needless to say, because of its beauty and rarity, many collectors and investors want to get these diamonds.

Argyles are also known as Sertour Pink Diamonds after the mine where they were first discovered by gemologists and mineralogists working on South Africa’s De Beers mining operations in 1920. Today, there are nine mines where these gems can be found, but only one of them – Argyle Mine – produces these blue-green gems with a distinctly patterned appearance. Even though it is found in such small quantities, this type of pink diamond is highly valuable because it is such an exclusive variant with no similarities to any other color or hue within its range.

How a Rarity of an Argyle Diamond is Discovered?

The discovery of the first pink diamonds at Argyle Mine in South Africa is credited to a group of gemologists and mineralogists who were working as consultants with the De Beers company. The company is known to be the world’s largest producer of pink diamonds and also owns the world’s largest pink diamond – the Pink Star. There is no specific name for the color of these diamonds, but they are usually described as a close relative of the classic pink diamonds. The origin of their color is a result of their formation process, which is under a very high pressure and temperature. The intense heat and pressure cause the carbon atoms in the diamond to mix with other elements such as nitrogen and hydrogen. The result is an interesting variety of colors that are found in only a few pink diamonds.

Why Are Argyle Pink Diamonds So Valuable?

Pink diamonds are very rare and possess a unique hue. The combination of the pink color with two intersecting patterns that result in inclusions or transparency make it a very desirable gemstone. However, because it is so rare, finding a pink diamond is even more difficult. The rarity of these rare pink diamonds is what draws attention from people who want to own or sell them. There are no other gems that have the same combination of factors which makes them so desirable. The high value of these pink diamonds has made them popular as engagement rings, wedding gifts and gifts for women who are celebrating a birthday or anniversary.

A Gemstone That Can Be Cut and Polished

Pink diamonds are very rare and possess a unique hue. The combination of the pink color with two intersecting patterns that result in inclusions or transparency make it a very desirable gemstone. The most common cut of pink diamonds is the round brilliant cut. However, because they are so rare, finding a pink diamond is even more difficult. The best way to view these gems is under a 10x loupe or 10x microscope. The cut and polish of a pink diamond should be even finer than that of a classic pink diamond. The color, pattern, clarity and carat weight of a diamond should be identical to that of a classic pink diamond. The only difference is the shape, as it is only an argyle.
