Lab-grown diamonds of various colors grown by the high-pressure-and-temperature technique. A synthetic diamond or laboratory-grown diamond (LGD), also called a lab-grown diamond, [1] laboratory-created, man-made, artisan-created, artificial, synthetic, or cultured diamond, is a diamond that is produced in a controlled technological process (in contrast to naturally formed diamond, which is ...
If the nitrogen atoms are dispersed throughout the crystal in isolated sites (not paired or grouped), they give the stone an intense yellow or occasionally brown tint (Type Ib); the rare canary diamonds belong to this type, which represents only 10% of known natural diamonds. Synthetic diamond containing nitrogen is Type Ib.
Most Ia diamonds are a mixture of IaA and IaB material; these diamonds belong to the Cape series, named after the diamond-rich region formerly known as Cape Province in South Africa, whose deposits are largely Type Ia. Type Ia diamonds often show sharp absorption bands with the main band at 415.5 nm (N3) and weaker lines at 478 nm (N2), 465 nm ...
The process just takes way less time (we’re talking a few months as opposed to billions of years), and the lab-grown diamonds have the same physical and chemical properties as natural diamonds ...
Lab-grown diamonds and natural diamonds have the same visual and chemical components, making them virtually identical. Same sparkle, same beauty, same brilliance, same longevity. Lab-grown ...
Since the 1950s, techniques can produce gem-quality diamonds of essentially any desired chemistry in sizes up to about 1cm. [6] Although some manufacturers do label their synthetic diamonds with serial numbers, there is no guarantee that a given diamond is not man made, although sometimes an unnatural chemical composition or pattern of flaws may suggest a diamond is synthetic.
The debate between lab-grown and natural diamonds is only set to get hotter in 2021. A November report by MVI Marketing estimated that lab-grown diamonds will “go mainstream” relatively soon ...
Synthetic diamonds are produced via high pressure, high temperature or chemical vapor deposition (CVD) technology. These diamonds have numerous industrial and commercial uses including cutting tools, thermal conductors and consumer diamond gemstones.
