What colors can be produced by diamond irradiation?
Blue, green and yellow are the most popular colors produced using the irradiation process. Orange, red and purple/pink colors are also possible which are more difficult to produce.
Are Irradiated diamonds safe/radiation free?
Yes, absolutely! I recommend that you look for diamonds that have been processed in the United States where laboratories adher to strict safety standards and government regulations. Diamonds colored in the USA are 100% radiation free.
How stable is color produced by the electron bombardment process EBT process?
The color changes produced in diamonds by the irradiation process are irreversible. The color is stable and permanent under normal wear and tear. The color is not affected by chemicals, ultrasonic cleaners, steam cleaning, polishing or heating up to 1000°F. Yellow, orange, red and pink colored diamonds are unaffected by heat even over 1000°F. Blue and green colors may fade when the diamond is heated over 1000°F. Special care of colored diamonds should be taken when resizing a ring or some jewelry repairs. Avoid exposing diamond to jewelers torch which may heat diamond to over 1000° F.
What type of diamonds are suitable for this process?
Any diamond with transparency irrespective of its original color and clarity can be processed using this process. Our recommended labs can suggest which color is most suitable for a particular diamond after visual and chemical analysis in the lab. In general, white diamond can be processed to any of blue, green or yellow colors. We recommend blue or green colors for diamonds that originally has a slight brownish color tone or black inclusions as this can mask the the original undesired color or inclusions. Diamonds with yellow tone can be processed to yellow color if it has no fluorescence or to green or greenish yellow color if the diamond shows fluorescence.

The strongest point of colored diamonds is just that – they’re diamonds. Their strength and durability can’t be matched by other stones. They’re available in sizes as small as 1mm, making them an ideal alternative to non-durable colored stones in smaller sizes. But their unique beauty lies in the fact that they can combine any color with that unforgettable brilliance of a diamond.
For instance, a sapphire is blue and certainly beautiful in its own right, but it can’t match the magical brilliance of a blue diamond.
Color enhanced diamonds have become very popular as jewelers and designers have realized the potential of their beautiful colors, availability and affordability. Color enhanced diamonds are natural diamonds that have undergone coloring procedures.
The wide range of rich colors has enabled jewelry manufactures around the world the opportunity to offer their customers fancy colored diamonds at an affordable price in a broad range of designs.
Color enhanced diamonds, just like many other treated gemstones are universally accepted. However, it is important for the seller to disclose that the diamond being sold has been treated. Federal Trade Commission guidelines require disclosure of gemstone treatments at every level of the trade.
I have created many engagement ring designs using color treated diamonds. This one here is one of my favorites. The ideal cut modern brilliant diamond weighing 1.57ct. is set in a swirling pave' set ring shank that spirals around the diamond and finger. Through heat and pressure we have been able to create one of the most intense orange colored diamonds I have ever seen.
For 25 years I been creating jewelry set with colored diamonds. It is my hope that with this blog I will be able to share my enthusiasm for diamonds of color with you. Diamonds mined from the ground can be found in almost any color of the rainbow, however natural color diamonds are rare, in some colors exceedingly rare, and therefore very expensive. Today through the use of modern technology we can permanently alter the color of diamonds. This gives you color in addition to the durability and brilliance diamonds have always been known for.
