Why coloured diamonds




















What is the D-Z scale? The D-Z normal color range begins at colorless like water and continues through to light yellow or brown.

This can include lush green, vibrant purple, exotic orange — literally any other color you can think of! Diamonds naturally come in every color of the rainbow yep red, blue, green, purple, pink, etc.

So, there are many different color diamonds! Some colors, such as red and blue, are much more rare than others. As a result of this rarity, these colors are much more expensive. On the other hand, less rare colored diamonds, such as champagne and black diamonds , can be much more affordable. So, selecting a fancy diamond for your colored diamond engagement ring may not be as crazy as you thought!

Truly, for every different color you can imagine, there is probably a fancy color diamond in the world that shade. They sure are!

Fancy color diamonds grow in the Earth, and we also grow real fancy color diamonds in labs! Diamonds get their color from the unique conditions in which they form. These specific conditions are so unique that only 1 in every 10, natural diamonds is fancy! Lab-created fancy diamonds have the exact same mineral makeup , as well as the same appearance, as natural fancy diamonds.

For example, both natural and lab blue diamonds can be vivid or more grey, and they both get their color from boron.

As a result, both the natural and lab diamonds are, in fact, real the FTC even says so! Consequently, both lab and natural diamonds make great colored diamond engagement rings. What I mean by that is that some diamonds get their color from treatments gem scientists give them. So, gem scientists safely irradiate them to make them change to more attractive colors. Most frequently, these colors include blue, black, green, and yellow.

Buyer Alert! Do Amore informs each customer about the natural, treated, or lab-created origin of the diamond they purchase. For the most part, yes, however, it depends on the color. Boron absorbs yellow light and thus reflects blue light; subtle differences in the concentration and positioning of these boron atoms result in different hues and shades of blue. Thanks to research by GIA scientists , we now know that the origin of natural blue diamonds is far deeper up to four times! We are lucky enough to find these beauties due to a process called subduction.

Just as you mix yellow and red paint to make orange, natural phenomena that cause color in diamonds can exist on their own or in combination, forming nearly any color in the rainbow.

Though not common, It is possible if a diamond with a plastic deformation like, say, a pink diamond also has enough nitrogen like a yellow diamond , you get an orange diamond. This serves as further proof that no two natural diamonds are ever exactly alike. While all natural color diamonds are beautiful in their own ways, what makes them extraordinary is their extreme rarity. Natural fancy colored diamonds comprised only 0. This means that the amount of pink diamonds recovered in a year would only fill a champagne flute.

As the Natural Color Diamond Association reports , only one natural blue diamond can be found on the market for every Picasso paintings up at auction. Red, green, purple and orange are the rarest. Backed by decades of research and the examination of thousands of colored diamonds, the GIA Colored Diamond Grading System has become the standard for evaluating these extremely rare gems.

Virtually every colored diamond sold at major auction houses has been graded by GIA. GIA researchers theorize that the color in many pink diamonds is caused by color centers that can selectively absorb light in the visible region of the spectrum.

Color centers are the result of lattice defects, or imperfections in the arrangement of atoms in a crystal.

These defects can sometimes cause pink graining in the diamond crystal. Most naturally colored black diamonds get their color from large quantities or clouds of minute mineral inclusions such as graphite, pyrite or hematite that extend throughout the stone. These diamonds may also have numerous cleavages or fractures that are stained black or have become black because of graphitization. Concentrations of these internal features are responsible for the coloration.

The presence of nitrogen causes a diamond to appear yellow. The intensity of the yellow color is dependent upon varying amounts of nitrogen. Once relegated to industrial use, brown diamonds gained cachet in the s when marketers gave them romantic names like champagne, cognac and chocolate.

The color in natural brown diamonds is caused by internal parallel brown grain lines due to distortion of the crystal lattice arrangement of molecules.

Brown diamonds are generally more affordable compared to other fancy colors. The presence of boron impurities is often responsible for the color of natural blue diamonds.
