Synthetic Diamonds: How to Detect if your Diamond is Natural or Synthetic

As in any industry, when a product is valuable and exclusive, imitations always appear. Diamonds are not an exception, and some would seek ways to replicate their beauty. This is the reason why recently, laboratory-grown or synthetic diamonds have become more common in the market, more technically advanced, and therefore, harder to detect.

What is a Synthetic diamond?

Synthetic diamonds have the same chemical composition, crystal structure, optical, and physical properties of natural diamonds. Synthetic diamonds are categorized by their production methods: high-pressure, high-temperature (HPHT) or chemical vapor deposition (CVD).

What's the problem with Synthetic diamonds?

Man-made diamonds market is worth about 2 percent of the total $87 billion diamond jewelry market sales and is due to increase its share to 5 percent by 2035, according to Zimnisky. Proportionally they represent a small segment of the market. However, they are becoming more widespread.

The main problem is that synthetic diamonds are virtually identical to natural diamonds, and differences only become clear when they are analyzed in a gem laboratory.


How can you detect if your Diamond is Natural or Synthetic?

As man-made diamonds are not detectable at first sight, GIA has become the main source for identifying diamonds.

If a diamond is found to be laboratory-grown, GIA issues a Synthetic Diamond Grading Report, which looks distinctly different from the standard grading report.

In addition, GIA also laser-inscribes the diamond’s girdle with a report number and a statement that the diamond has been laboratory-grown.
