Can Lab Grown Diamonds Be Colored?

Can Lab Grown Diamonds Be Colored? Short answer: Yes! Diamonds that are grown in labs are colorable, and often, beautifully. However, as with everything else (and sparkles), the finer particulars are what make the difference. Let's look at how color occurs, what colours remain permanent, and which questions you should inquire about before purchasing.
How Does Colour Appear? During Growth or After?
There are two ways that a lab-grown diamond is colored:
-
During Growth:
When the diamond grows, certain laboratory procedures introduce trace elements as the diamond is formed. For instance, small quantities of boron can create blue hues, while nitrogen can produce brownish or yellow shades. If the colour is integral to the crystal's growth, it is stable and lasts forever. -
Post-growth treatments:
The diamonds (both mined and lab-grown) can also be colored after their formation. Techniques such as irradiation, heat treatment, or high-pressure and high-temperature (HPHT) processing can alter the crystal structure of the stone or the impurities that alter the appearance of the stone. These procedures can cause or enhance the appearance of fancy colours. They are typically reported in reliable laboratory reports.

Which Colours Are Common And Which To Watch For?
Diamonds grown in labs are available in a variety of colours including classic blues and yellows, delicate pinks and cognacs, and even extreme "fancy" shades. Certain colours (like certain yellows and blues created in the lab) are inherently stable and long-lasting. Some may result of treatments, but still beautiful, but you'll need to be able to see the difference.

What to Ask When Buying a Coloured Lab Diamond
If you're looking for lab diamonds, be sure to ask these questions to be answered in a practical way:
-
"Is the color inherent to the stone or is it the result of a treatment?"
-
"Does this stone come with an assessment report from an independent laboratory that reveals treatments?"
-
"How long will this color last? Will it fade after exposure to heat or light?"

Care and Value Considerations
Colored lab diamonds offer attractive looks at a lower cost than other fancy-color stones. But, the treatment may alter the value of the stone and also care instructions, so be sure to document the procedure and adhere to recommended maintenance and cleaning routines.
