Know More About Synthetic Diamonds and Its Treatment for Color Change

by ABD Diamonds Pvt. Ltd. Leading Diamond Manufacture & Supplier
Synthetic diamonds are created in labs and have essentially the same process as natural diamonds. It isn't easy to differentiate between synthetic diamonds and natural diamonds as their chemical composition, structure, and physical properties are similar. They cannot be considered fake diamonds but are also not the same as natural diamonds.

Can synthetic diamonds be used in jewelry?

Yes, synthetic diamond manufacturers design high-quality diamonds with a wide range of sizes and colors as natural diamonds. Many companies offer factory-made diamonds colorless, pink or blue diamond, with each diamond marked as a lab-grown.

Synthetic diamonds

Synthetic diamonds have been produced since the 1950s to use in laser optics and as abrasives. Until 1970 the research at GE created its first quality gem as synthetic diamonds. The lab grown diamond supplier provides quantities of gem-quality diamonds primarily small in size and brown in color. Still, the quality continued to improve today in terms of appearance.

Synthetic diamonds are made in a few days or weeks in today's advanced laboratories. The two major processes that help in manufacturing fancy cut diamonds are HPHT and CVD process.

HPHT process: With the HPHT process, synthetic diamonds are produced in a lab through advanced equipment and procedures to look like natural diamonds. The color of HPHT synthetic diamonds has evolved with technology. Colorless or near to no color, the HPHT process for treating diamonds can also turn the stones pink, blue, or any other color.

CVD process: This is a new process that involved carbon-containing gasses inside the chamber onto diamond seed plates. The crystals are tabular in shape and edged with graphite. These crystals can often become colorless, and the CVD diamond process is chosen to polish the gems to give clarity to the natural parts with grades from VVS2 to VS1 range. Most of the synthetic diamonds receive clarity in the VS2 to SI1 range.

Changing the color of the synthetic diamonds through advanced treatments

Most HPHT diamonds are colorless, but they can turn out blue when grown in more quantity. With nitrogen, they attract to yellow color, and when grown with nickel, they go green. CVD diamonds are initially brown. Although nearly colorless, HPHT can improve the color of the CVD diamonds, such as reducing brown color on the D-to-Z scale range. There are multiple steps involved in the process that can give color to a synthetic diamond.

Irradiation and heating are the primary processes that can combine and change the color of a diamond to pink, green, and red. People prefer fancy cut diamonds that have different colors or can be treated natural diamonds as alternatives.
