The Differences Between Lab and CVD Diamonds
With so many options out there, choosing the right diamond can be difficult and confusing. But if you want to make an informed decision and get the best value, it’s important to know the differences between Lab diamonds and CVD diamonds. Let’s take a look at their differences!
What are Lab-Created Diamonds?
In contrast to mined diamonds, synthetic diamonds manufactured in a lab environment. Although there are two general methods of creating synthetic or lab-created diamonds—chemical vapour deposition (CVD). Lab diamonds or high-pressure, high-temperature (HPHT)—the term synthetic diamond is a bit of a misnomer since these diamonds are chemically, physically, and optically identical to mined stones. You might also hear synthetic diamonds referred to as laboratory-grown, cultured, or engineered diamonds. The latter two terms focus on process rather than the location of manufacture, so for clarity’s sake, I’ll stick with synthetic when referring to Lab diamonds in general.
So how are they made? Like Lab Grown Diamonds, synthetic (lab-created) diamonds start as nothing more than carbon. Under heat and intense pressure, the black dirt (carbon atoms) converted into an opaque yellow colour that eventually becomes clear by removing excess weight through cutting and polishing. Before manufacturers began reproducing diamonds under controlled conditions, one method involved using nuclear reactors to burn graphite at extremely high temperatures inside a nuclear reactor until only carbon remained—or supercompressing coal into chunks of hard black carbon known as lumps or chunks Lab diamonds.
What are Cubic Zirconia (CZ) Stones?
Cubic zirconia is a man-made diamond simulant that has been in use since 1977. These stones have their origins in a quite complex lab process. The quality of cubic zirconia assessed via three criteria: brilliance, fire, and durability. Top grades diamonds possess all three characteristics; those with even one area lacking considered man-made imitations by consumers. Despite these synthetic origins, cubic zirconia still composed of natural materials that come from above-ground sources—and it also created using equipment used for mining real diamonds. As such, lab diamonds are entirely within compliance with diamond industry standards set forth by organizations like De Beers.
What is the Difference Between Real and Fake Gems?
If you not know already, real gems those that dug up from under the ground. Fake gems created by fusing synthetic stones with lab-grown materials in a petri dish. Real diamonds mined from alluvial deposits, which is why it takes such an insane amount of time to find them. they only come out every so often when they found at their original locations. With that said, there another difference between real and fake diamonds: clarity. That’s right—diamond clarity another thing that sets lab diamonds apart from their earth-made cousins.
Life Cycle of Lab-Created Diamonds
In terms of lab-created diamonds, it’s important to note that many companies claim to create diamonds. Some take a high-tech approach while others claim they do it all by hand. In reality, all labs use computers when cutting diamonds. The actual process is similar to how people think about cutting real diamonds—one person pulls a lever while another monitors a computer screen. Once created, Lab Grown Diamonds have their chemical makeup analyzed using equipment designed for diamond testing labs. However, tests for authenticity not as sophisticated as those used in diamond testing labs (where natural stone is tested). Once verified, a laser inscribes an international identification number into each stone so consumers know what they’re getting when buying a lab-created diamond.
How to Identify CVD vs. Lab Grown Gemstones?
There are two main ways to Lab Grown Diamonds: through laboratory processes or in a controlled-environment facility. If you interested in purchasing a gemstone, it important to understand what type of gem you are buying—for instance. if you looking for an engagement ring with Lab diamonds set stones, knowing which type of diamond more valuable make a big difference.
