What Gives Colored Diamonds Their Color?

As someone working in the diamond industry, I'm often asked what gives the various colored diamonds their coloring: Broadly speaking, there are two mechanisms that can cause a diamond to come into being with a color other than the more typically thought of white (or to be accurate, clear) color diamond;

Mechanism 1: Corruption from other elements causing color changes Pure flawless diamonds crystals are made only of carbon atoms that are tightly packed in a pattern known as the "lattice". However, during the formation process, the tightly packed lattice of crystal can become embedded with specs of other element atoms other than carbon. Due to the limited space and shape afforded by the lattice only a handful of elements can theoretically take the place of carbon atoms in this way; namely: Nitrogen, Boron, Phosphorus, Hydrogen, Nickel, Cobalt, Silicon, and Sulfur. Such element "corruption" lend the diamond a distinct tint, with higher degrees of corruption leading to higher degrees of coloring;

Mechanism 2: Deformation of the carbon atoms causing color changes The second way for a diamond to gain a different color, is from environmental factors causing a changes in the actual structure of the carbon atom particles (i.e. change in electrons) or in the layout (spacing, symmetry, and pattern consistency) of the lattice. Such examples of environmentally caused deformation include the impact of traveling to earth surface and radiation exposure.

Blue Diamonds are caused the presence of boron atoms in the diamond lattice. Yellow and orange diamonds are caused by the presence of nitrogen atoms in the lattice. Brown diamonds are caused by an irregular microscopic pattern of the lattice, essentially a rough diamond. Nitrogen corruption can also cause a brown shade. Green diamonds are usually caused by radiation exposure! Unlike deformation changes, the change is only to the superficial particles, therefore one should be careful polishing a green diamond as it can lose its color.

Red, purple and pink diamonds Although the precise mechanism is unknown; red, purple and pink diamonds are caused by a distinct deformation of carbon atoms structure (change of electrons) that somehow occurs when traveling through mantle to earth's surface. These colors are among the rarest of the diamond types.

Black and gray diamonds are caused by clusters (not single atoms) of graphite and iron filling large voids in the lattice. Other color variations and causes exist, and you can have crossovers of the above color changing factors leading to unique shades. There are also many artificial methods for coloring diamonds, but to date all these methods produce results that appear comparatively crude under microscopic inspection, therefore artificially colored diamonds do not carry nearly the same value as their naturally produced counterparts.

Makeityourring - if you are buying a diamond ring for someone

Chances are, if you are buying a arena for someone, you want your diamond to be special, tough, and a lot of all, authentic. Using all of the imitation diamond jewelry available today, it is sensible to know a couple of tips and tricks on how to determine a real diamond from a faux.

Find out the ways of the trade and bring together a couple of of these simple methods up your sleeve. It is time to put the diamond to the test.

1. Real Diamonds are flawed; fakes are not.
Even though most may feel that the target in buying the great diamond is to uncover one that is virtually flawless—that is not often the case. Cautiously made Cubic Zirconia is equipped with absolutely no imperfections, producing it simple to label as pretend. Real, authentic diamonds contain tiny ‘flaws’ that oftentimes generates a brilliance that cannot be observed in fakes.

2. Glimpse interior your Diamond.
Considerably enjoy seeking inside a crystal ball, looking inside the diamond should share the truth about its accurate elements and its authenticity. The key is: Real diamond rings always have something inside. If you glimpse into the diamond with a 1200x microscope, you should be able to see very small inclusions inside of the gemstones infrastructure. If you hold the diamond in entrance of the eye and glimpse through its facet, you should not be capable to see in it, nor must it glimpse to be one clear, unified coloration. If the jewel exerts zero levels of brilliance, and if one can see through it from the side, then it is certainly faux.

3. Look at the Setting & Mount.
Because stones produced up of mimicking substances like Cubic Zirconia and Moissanite are so much less expensive than diamonds, these folks are generally set in less expensive metals. Possibility are, a fake diamond would not be set in real gold.

4. Check the Put on and Tear of the Stone.
Real expensive diamonds possess remarkable durability and a hardened sharpness that is hardy adequate to scratch glass. If there or any scratches or nicks as a face of your Makeityourring Diamond Engagement Rings, or if you can generate them, after that the diamond is not real.

Basic Two-Minute Tests
1. The Studying Test.
If the diamond is not mounted, set it on a newspaper. If it is easy to see through it at all, also if you merely see distorted black smudges rather than clearly-marked letters, in contrast to your diamond is a pretend. Real expensive diamonds have a lot intricacies in their infrastructure that it is unattainable for burn to pass all like in them without becoming first refracted.

2. The Sandpaper Trial.
Diamonds are the toughest known substance. Which becoming said, it is unattainable for real diamond jewelry to be scratched. Employing whether wet or dry sandpaper, trial the diamond by scratching it vigorously on the brittle stretch of the paper. If it becomes nicked, it is surely a pretend.

3. The Sparkle Trial.
Check out the diamond from the top, then from the facet. Examine the sparkly, reflective properties which you may have seen when looking straight down onto the accept of the diamond, with like your diamond shines and reflects when being seen at a facet angle. Mimicking diamonds are purposely made to glance like real expensive diamond jewelry from a birds-eye-view, but are less commonly apt to be able to bring individuals same traits all through the rest of the stone.
