Lab-grown diamonds aren't considered as valuable as natural diamonds primarily because they lack rarity, can be mass-produced, and their supply isn't limited, leading to rapidly falling prices and poor resale value, with consumers often paying less upfront but receiving minimal return on investment compared to the perceived scarcity and status of natural stones. While they offer ethical and budget benefits, their availability undermines the exclusivity that drives financial value in mined diamonds, making them poor financial assets but great for personal enjoyment.
Lab diamonds are mass produced therefore their value will continue to go down as there is no cap on how many are released into the market. BOTH lose value almost instantly as you walk out of the store because of retailer markups.
One common perception is that lab-grown diamonds are 'tacky' because they aren't sourced from the Earth. However, their formation process does not affect their quality or appearance. In fact, it's nearly impossible for even trained gemologists to distinguish between the two without specialized equipment.
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.
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.
Their popularity in the U.S. luxury market is rising due to increasing consumer interest in sustainability, affordability, and personalized luxury products. Leading brands like Signet Jewelers and Pandora are integrating lab-grown diamonds into their collections to meet this growing demand.
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.
In short, lab grown diamonds are incredibly durable and, with proper care, can last a lifetime – and beyond. In fact, they are likely to remain beautiful for generations, making them an excellent choice for heirloom jewellery.
Lab diamonds are created in a matter of weeks vs the billions of years natural diamonds take to form. It's impossible to tell and lab and mined diamond apart, without specialist equipment. A lab diamond is not a fake diamond, or a diamond simulant – it is an authentic diamond.
The average price of a 1 carat lab grown diamond is currently $732 (see price chart below). 1 carat lab grown diamonds can cost anywhere from $446 - $1,590 depending on the diamond's shape, color, clarity, and other factors.

Types of Diamond Cuts and Their Characteristics
Round brilliant is the most popular and highly sold cut. Its brilliance and symmetry make it timeless. Because of its strong demand, it commands the highest resale value.
Lab-grown diamonds lose most of their value immediately after the purchase. They have significantly lower resale value, often less than 10-30% of their original retail price because they are easy to mass produce.
No, Tiffany & Co. primarily sells natural, mined diamonds, emphasizing their ethical sourcing and origin, but their parent company LVMH is exploring lab-grown diamonds in other luxury brands, with some jewelers offering "Tiffany-style" settings for lab-grown stones. While Tiffany focuses on mined stones and their provenance, the broader market sees a rise in lab-grown options, with many other retailers providing them for those seeking alternatives to natural diamonds.
For around $5,000, you can typically find a natural diamond ranging from 0.5 to 1.5 carats, depending heavily on quality (the 4Cs), cut, setting cost, and if it's lab-grown, but a good quality 1-carat diamond often starts near this price point. A $5,000 budget could get you a significant stone like a 1-carat diamond or even larger lab-grown options, but quality factors (color, clarity) will significantly impact size and price.
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.
Gemologists and professional jewelers cannot distinguish between a lab-created diamond and a natural one through the naked eye.
A lab-grown diamond might look like a natural diamond, but so do cubic zirconia and moissanite. The perceived value will change as they get cheaper and will be similar to the other fake alternatives. My conclusion is, don't buy a lab-grown diamond for your engagement ring.
