What are man-made diamonds? Are they real diamonds? Man-made diamonds have been produced for industrial purposes since the 1950s and are used in a wide variety of applications: telecommunications, laser optics, healthcare and more.
Laboratory-grown diamonds (also sometimes referred to as man-made or synthetic diamonds) entered the gem and jewelry market in commercial quantities about five years ago. Although identical in appearance to natural diamonds, they have very subtle differences that can only be detected by trained gemologists and sophisticated equipment designed ...
We created the GIA iD100®, a desktop instrument to help jewelers distinguish natural diamonds from laboratory-grown diamonds, diamond simulants and some treated diamonds in under two seconds. Laboratory-grown diamonds can also be sent to gemological laboratories like GIA for identification.
Laboratory-grown diamonds (LGD s) go by many different names—synthetic, created, man-made. What these names mean is that laboratory-grown diamonds were made by humans in a lab or factory rather than by nature. But are lab-grown diamond real diamonds? They are.
The man-made material will have essentially the same chemical composition, crystal structure and optical and physical properties as the natural gem gemstone. Some of these man-made gems are used to imitate diamond: synthetic rutile, colorless synthetic spinel, and colorless synthetic sapphire.
GIA has studied lab-grown or manmade diamonds extensively over the past 30 years, and we know a great deal about the methods used to produce them and how they can be recognized. While synthetic diamonds are produced in factories, their chemical and physical properties correspond very closely to that of natural diamonds.
Today, man-made diamonds have become more common and are more difficult to identify on your own without help from a reputable gemological laboratory like GIA. Understanding your origin story. The geographic origin of a natural diamond cannot be determined through evaluation of a polished stone.
The new GIA Laboratory-Grown Diamond Report will feature the same visual representation of the scales for color, clarity and cut as GIA’s grading reports for natural diamonds. The updated reports will continue to use descriptive terms for color and clarity, for example, Near Colorless and Very Slightly Included, as shown on the scales.
Beginning July 1, 2019, GIA Laboratory-Grown Diamond Reports and identification reports no longer use the term “synthetic.”. The GIA Laboratory-Grown Diamond Report includes the standard GIA color, clarity and cut grading scales for reference purposes.
The GIA iD100 ® gem testing device combines advanced spectroscopic technology and more than 60 years of GIA diamond and gemstone identification research to deliver a sophisticated and easy-to-operate desktop instrument to screen your stones.
