Many traditional jewelers tell customers that Lab Created Diamonds have absolutely no value, but this could not be further from the truth. Most Earth-Mined Diamonds have resale value, and most Lab Created Diamonds will have a similar resale value, as well.
The bottom line: Overall, lab grown stones share the same physical and chemical properties as natural diamonds. Lab grown diamonds are real diamonds that last forever but are an estimated 30% less expensive than mined diamonds. Overall, neither diamond is “better.” They are not in competition with one another.
Some people may refer to lab created diamonds as “fake diamonds”, imitations or simulants, but this is incorrect. Lab created diamonds share the same or similar chemical and physical properties as a natural diamond produced by the geological processes of Mother Nature.
Today, lab diamonds are coming in significantly cheaper than natural diamonds. From 50-60% cheaper, or even more in some cases. For an example of the price difference between natural and lab-grown today, take two diamonds from James Allen. The first is a natural 1.01-carat G VS1 round diamond, which costs $6,440.
Cubic zirconia is also a synthetically created stone, but its crystal structure and chemical composition are completely different. While lab-grown diamonds consist of carbon, cubic zirconia, also known as CZ, is the cubic crystalline form of zirconium dioxide and contains zero carbon.
Can you resell a lab created diamond? Yes, you can resell a lab grown diamond. Ada Diamonds buys independently-graded, high quality lab diamonds from the public through our Public Purchase Program.
“There's nothing rare or distinct about a lab-grown diamond,” says Benjamin Khordipour GG, Chief Gemologist at Estate Diamond Jewelry. “There is no market cap on how many can be made available, and for that reason, they are almost completely worthless. No one in the jewelry trade wants to buy them.”
Absolutely not. The color and clarity of laboratory diamonds will not change over time - they are diamonds, just like those that come from the mines, Ye-hui commented. In fact, colorless lab-grown diamonds are typically Type IIa (pronounced two-a) diamonds.
Lab grown diamond fluorescence is caused by submicroscopic structures within the crystal. Blue fluorescence is most commonly associated with the presence of nitrogen atoms aligned in specific arrays within the carbon lattice. Most diamonds that exhibit strong blue fluorescence appear a bit hazy in regular light.
Lab diamonds really do last forever, and there's nothing that will dull the shine or interfere with the brilliance of synthetic diamonds. It's not for nothing that they say it's impossible to tell the difference between a natural diamond and a man-made one.
Yes! Lab grown diamonds test positive on a diamond tester because they're made of crystallized carbon, just as mined diamonds are. Although, because some HPHT diamonds may carry impurities (although unnoticeable to the naked eye), there is a chance they could test as moissanite or non-diamond.
There is no visual difference in Lab Created Diamonds vs Natural Diamonds. They sparkle the same, have the same types of color and clarity, and can come in the same sizes and shapes. Likewise, Lab Grown Diamonds are just as hard as Natural Diamonds.
Lab-grown diamonds are purer than the stones mined naturally, because unlike mined stones, synthetic diamonds do not have any dirt or impurities ingrained in them. They also have fewer defects, and show fewer signs of strain in their crystal structure, because they are made under carefully controlled conditions.
Disadvantages of lab-created diamonds
|Lab-Created Diamonds||Naturally-Mined Diamonds|
|Priced 20-40% lower than naturally-mined diamonds||Priced up to 40% higher than similar lab-created diamonds|
|Decrease in value over time||Increase in value over time|
