Did you ever walk into a jewelry store and see blue diamonds, pink diamonds, yellow diamonds, or green diamonds, and wonder how they got to be that color by nature? Yes diamonds come in all of these colors, and more naturally When a diamond appears colorless, white light or daylight ( all the colors of the spectrum combined) enter the diamond and are all absorbed so no color is reflected back to the eye. Color in diamonds is absorption and reflection of light. This is caused in three ways: Diamonds are pure carbon so something else was caught in the stone during the formation of the diamond which changes the absorption spectrum. Take yellow and orange diamonds for example they contain nitrogen while blue diamonds contain boron. Gray, violet and some green diamonds contain hydrogen. As you can see these are all elements that were caught in the stone during its formation. So what is another way green diamonds get their color bet you can never guess? Give up well here is the answer: (Natural Radiation) which over millions of years alters the atomic structure of the diamond thus changing the absorption spectrum to give it a green appearance. No natural green diamonds are not radioactive, so you do not have to worry about wearing them. How do pink, red or brown diamonds get their color? Plastic Deformation; yes thats right plastic a twisting of the atomic structure of the carbon atoms during the formation of the diamond in the earth. How ever they get their colors they are beautiful to look at nature has out performed herself when it came to the making of colored diamonds. You can also color a diamond by radiation Nu Age Tecnologies is one of many companies that does this treatment and they can color a white diamond blue, green, yellow, and orange. If you are buying a colored diamond you should make sure if it is color treated or colored from nature. Diamonds that are colored by nature are more expensive then a color treated diamond. |
