I can understand how some ladies might want a colored diamond like a pink diamond for instance. Let’s face it: she’s going to wear that ring for the rest of her life so of course, she wants it to say something about her, who she is, etc. Hey, if you’re eyes are rolling right now and you’re muttering ‘Yeah, chicks…’ No, that’s the wrong attitude. I intend to drive my truck for a long time so guess what? I painted it hunter green, not pink. Color is important.
However, since only one in every 10, 000 diamonds possess natural color, we know, going in, that these diamond will have a higher cost.
To keep the price down, always return to the 4-C’s: Color, Carat, Cut, and Clarity.
Naturally, a colored diamond whether a pink diamond or black diamond will be the main focus of your purchase, it’s deepness, the intensity. The first question you have to ask yourself is do you want a naturally colored diamond or one that is artificially colored? Yes, a pink diamond is damn beautiful though!
Color-treated diamonds are regular diamond that weren’t all that desirable, like pale yellow. Then the color is enhanced dramatically. It can even be changed to shades of blue, or purple or red.
The process is called High-Pressure High Temperature (HPHT). This procedure is also used to “paint” colorless diamonds. For instance, an extremely light brown diamond can be changed into a D colorless diamond, the highest grade of color. Other colors like the greens and pinks are achieved through dyeing or irradiation.
Some people don’t mind that their color came from a machine, others do.
Naturally occurring colors happen via HPHT, but it’s in the ground, not a device. The beautiful colors come from things like impurities and defects, a fact that always makes me feel good about my own life. Ha!
Brown diamonds occur because of a structural defects known as lattice. On the molecular level, it’s a deformation that causes certain wavelengths of light to be absorbed and others reflected. As it forms, the stones color spectrum is in the pinks moves to red and finally brown.
Is there anyone out there who hasn’t seen a cartoon image of glowing green light associated with radiation? There is a reason for that! It’s true! Green colored diamonds get their color from the naturally occurring radiation just below the earth’s surface.
Blue and Gray diamonds have traces of boron trapped within their structure giving us those shades.
Geologist have no idea why purple diamonds are purple. At least they’re honest. They do have a theory that it is due to post-growth plastic deformation. Since I’m certain we all know what that means I’ll go look it up.
“Plastic deformation is a process in which permanent deformation is caused by a sufficient load. It produces a permanent change in the shape or size of a solid body without fracture, resulting from the application of sustained stress beyond the elastic limit. Plastic deformation can be applied in the creation of a variety of items constructed with metal or plastic, and can be conducted under controlled circumstances, or may occur unintentionally. Plastic deformation is also known as plasticity.” (a definition shamelessly picked up here; so… this is what geologists do for fun!?)
Geologists believe this post-growth deformation happens when the diamond travels from the mantle to the surface through magma. No wonder they’re rare.
Yellows and oranges develop because the element nitrogen becomes trapped inside before the crystallization process takes place.
Then our mysterious black diamonds exist because of the tiny amounts of graphite or iron that makes its way inside.
They are all gorgeous diamonds. But to keep the price steady try this: you have your color picked out, right? Say you were all set to pay for a full 1.0-carat diamond. Have them slice it to .8, you’ll never miss it and the price comes down.
Because it’s a colored diamond you can even pick one with a couple of inclusions in its clarity because they won’t show. Again, the price goes down.
Then if you were going for a grade Excellent cut, a grade ‘Very good’ won’t appear any different either. You could end up not affecting your budget at all and still bring her the ring she’s always wanted. You have to admit, that’s not a bad way to start.
