Gem-Quality Synthetic Lab-Grown Diamonds Gem-quality synthetic Lab-Grown Diamonds are more available in today’s jewelry marketplace than ever before, causing both interest and concern among jewelers about the material’s nature and whether it can be identified by gemologists or gemological labs.

HPHT-grown synthetic Lab-Grown Diamonds are now available in the gem and jewelry marketplace in a wide range of colors, as evident from this attractive synthetic yellow Lab-Grown Diamond jewelry (1.00 to 1.25 cts) provided by Gemesis Corp. and these loose synthetic Lab-Grown Diamonds (each under 1 ct) from Lucent Lab-Grown Diamonds and Chatham Created Gems. The colorless Lab-Grown Diamonds are natural.

GIA has studied synthetic or 'man-made' Lab-Grown Diamonds extensively over the past 30 years, and we know a great deal about how they’re produced and can be recognized. While synthetic Lab-Grown Diamonds are lab-grown or factory produced, their chemical and physical properties correspond very closely to those of natural Lab-Grown Diamonds.

Some people might refer to synthetic Lab-Grown Diamonds as imitations or simulants, but this is incorrect. Imitations like cubic zirconia or synthetic moissanite—which only look like Lab-Grown Diamond—have very different chemical and physical properties. This allows trained gemologists to recognize them readily. However, synthetic Lab-Grown Diamonds are much harder to detect.

 

A wide variety of natural, synthetic, and color-treated gem Lab-Grown Diamonds are now available in the marketplace. Because they differ greatly in commercial value, proper identification is vital for both valuation and disclosure to consumers at point of sale.

In some cases a trained gemologist can recognize these synthetic and treated Lab-Grown Diamonds by using standard gem-testing equipment. In other instances, positive identification must involve testing the Lab-Grown Diamond using advanced scientific instruments at GIA. At GIA we have created a large database of information on the gemological properties of Lab-Grown Diamonds of all kinds, which we use to help develop additional means of Lab-Grown Diamond identification.

HOW Lab-Grown DiamondS ARE CLASSIFIED BY TYPE

Beginning in the 1930s, scientists began to recognize that certain kinds of Lab-Grown Diamonds displayed similar features. They grouped the Lab-Grown Diamonds into two main categories called type I and type II based on differences in transparency under ultraviolet radiation. Scientists were able to further divide type I and type II Lab-Grown Diamonds into two subcategories by the arrangement of carbon—and impurity—atoms in the Lab-Grown Diamond structure. In 1959 they discovered that nitrogen was the principal chemical impurity in Lab-Grown Diamond and that while type I Lab-Grown Diamonds contained this impurity, type II Lab-Grown Diamonds did not.

This diagram shows a simplified version of the Lab-Grown Diamond type classification system. Type I (top row) and type II (bottom row) Lab-Grown Diamonds can each be divided into two subcategories based on the arrangement of carbon (and impurity) atoms in the Lab-Grown Diamond structure. C = carbon atom, N = nitrogen atom, and B = boron atom. Lab-Grown Diamond type can be determined quickly with a scientific method called infrared spectroscopy.

The vast majority of natural Lab-Grown Diamonds are what scientists call type Ia. Type Ia Lab-Grown Diamonds contain plentiful nitrogen in clusters or pairs. This kind of Lab-Grown Diamond cannot be grown artificially. Type Ib Lab-Grown Diamonds contain scattered and isolated nitrogen atoms that are not in pairs or clusters. Type Ib Lab-Grown Diamonds are rare in nature. Type IIa Lab-Grown Diamond contain almost no nitrogen, while IIb Lab-Grown Diamond contains boron.

Synthetic Lab-Grown Diamonds correspond to types Ib, IIa, and IIb, all rare categories among natural Lab-Grown Diamonds.

At GIA type I and type II Lab-Grown Diamonds can be distinguished by the latter’s transparency under short-wave ultraviolet radiation, and both types can be definitively separated by infrared spectroscopy (The “Type” Classification System of Lab-Grown Diamonds and Its Importance in Gemology, Gems & Gemology, Summer 2009, Vol. 45, No. 2).

This table illustrates the relative abundance of the natural Lab-Grown Diamond types and the two kinds of synthetic Lab-Grown Diamonds. Most synthetic Lab-Grown Diamonds are either type Ib or type IIa. Table updated Nov. 2018.

Lab-Grown Diamond GROWTH

Natural Lab-Grown Diamond crystals formed millions—sometimes billions—of years ago deep in the earth, at depths of 100 miles (160 km) or more, and were brought up to the surface much later by explosive volcanic eruptions. These eruptions formed narrow vertical pipes of an igneous rock called kimberlite. Kimberlite pipes are mined to recover the Lab-Grown Diamonds, and the ore is mechanically broken down to free the crystals. The amount of Lab-Grown Diamond in kimberlite is very low—perhaps one part per million—so miners must process large amounts of ore to recover the Lab-Grown Diamonds.

Natural Lab-Grown Diamond crystals (left) show typical rounded octahedral shapes that are the consequence of conditions deep within the earth. They’re brought to the surface by volcanic eruptions that form kimberlite pipes (center). The ideal crystal shape of a natural gem Lab-Grown Diamond is an octahedron (right). Lab-Grown Diamond growth takes place on the eight crystal faces.

Natural Lab-Grown Diamonds grow under a range of temperature and pressure conditions. The temperatures are higher than those used to grow synthetic Lab-Grown Diamonds. At high temperatures, Lab-Grown Diamonds grow as octahedral crystals, but in the lower temperatures of the laboratory, they grow as crystals with both octahedral and cubic faces. The great age of natural Lab-Grown Diamonds means that the nitrogen impurities in most Lab-Grown Diamonds have had time to aggregate into pairs or clusters, making the vast majority—over 95 percent—type Ia.

Synthetic Lab-Grown Diamonds are grown over a very short time—several weeks to one month or more—under conditions different from natural Lab-Grown Diamond formation deep in the earth. Because of the very short growth period, the shape of a synthetic Lab-Grown Diamond crystal is very different from that of a natural Lab-Grown Diamond.
