Yes, lab-grown diamonds can and often do have fluorescence, just like natural diamonds, but their characteristics can be more controlled or even engineered, with blue being common, though many colorless lab diamonds have little or no glow, while fancy colors often fluoresce, sometimes enhancing their appearance, especially under UV light or strong sunlight.
No, a jeweler generally cannot tell if a diamond is lab-grown just by looking at it with the naked eye; they need specialized, lab-grade equipment like GIA iD100 or X-ray luminescence (XRL) testers to detect subtle differences in growth patterns, impurities, or fluorescence, as lab-grown diamonds share the same chemical and optical properties as natural diamonds. While some jewelers have machines to test, professional grading labs (like GIA) use advanced methods to identify them, often relying on laser inscriptions and grading reports for confirmation.
The main disadvantages of lab-grown diamonds are their lower resale value and investment potential, due to mass production and increasing supply, and a lack of traditional sentimental value for those who prefer naturally formed gems with geological history. They also face market perception gaps, with some still viewing them as less prestigious or "fake," and their production involves significant energy consumption, though environmental benefits compared to mining are debated.
Additionally, the Tiffany Gemological Laboratory will not accept stones exhibiting strong or excessive fluorescence, which, in natural lighting, can give diamonds a milky appearance. At Tiffany, laboratory experts determine the color of each diamond by comparing it to authenticated “master” diamonds.
They make great costume jewellery, but they are not suitable for sale in a quality jewellery shop. Sure, they are chemically, physically and optically almost identical to natural diamonds and will look flashy and sparkle well. But there is no soul or identity to them.
The answer is that a lab-grown diamond is a real diamond. Compared to mined stones, they're just as beautiful. They have the same chemical and physical properties, features, clarity, color, and size grades and are certified. At the same time, there is a significant difference between lab-grown and natural diamonds.
Tell people whatever you want to tell them in the context of the moment. Lab diamonds are diamonds. Some people judge lab diamonds because they are uninformed or because they feel like the rise of lab diamonds “cheapens” the meaning of diamond rings. Some people judge mined diamonds because of ethical concerns.
At the bare minimum, the stone is unlikely to lose any value over time. Lab-grown diamonds, on the other hand, are a relatively newer entry to the market. While they share the same physical and chemical properties as mined diamonds, their infinite supply makes them less rare and, therefore, less valuable.
Tiffany & Co. sued Costco for trademark infringement, alleging that Costco's sale of six-prong diamond rings with tags and signs using the name "Tiffany" (or "Tiffany-style") misled customers into thinking they were buying genuine Tiffany products. Tiffany & Co. argued the rings were counterfeits, while Costco claimed "Tiffany" referred to the generic six-prong setting style. The nearly decade-long legal battle ended in a settlement in 2021, after courts had mixed rulings on the "generic" term issue.
A G color diamond looks slightly whiter than an H, though the difference is so subtle it's almost impossible to see without expert comparison. For most buyers, an H color diamond offers better value, since it appears just as white to the naked eye when set in jewelry.
The answer to our central question is clear: yes, wealthy people increasingly buy lab-grown diamonds—and they do so with full awareness and intentionality. This trend reveals something profound about the evolution of luxury itself. Luxury is no longer measured solely by what is rare or what costs the most.
Whether it is natural or Lab grown diamonds, both last forever. A possible difference could be from where you buy them. Quality varies in terms of cut, clarity, and certification. A poorly cut diamond will not shine as much or may be sold cheaply.
Better Profit Margins
While lab diamonds jewelry cost less than natural diamonds, they still offer good profit margins for jewelers. This makes them a win-win - customers get better value, and jewelers can maintain healthy businesses.
Costco sells diamonds with a cut grade of Good to Excellent. Although treating diamonds is an accepted practice among many jewelers, Costco only sells natural and untreated diamonds.
The Gemological Institute of America (GIA), the world's leading authority on diamonds, has announced a big change. From late 2025, they'll stop using their famous 4Cs grading system for lab-grown diamonds. This move marks a definitive moment in the ongoing separation of natural diamonds from lab-grown diamonds.
Mobile apps may mimic testing, but they can't match the accuracy of professional instruments. Your phone won't replace a professional appraisal, but it can assist. Use the flashlight to observe how the stone handles light. A real diamond will produce sharp flashes and concentrated brilliance.
