Lab-Grown diamonds

Natural diamonds are found in the wild, while cultivated diamonds are created in factories. Lab-grown diamonds are identical to those found in nature. Both types have the same physical, chemical, and optical properties. Only strenuous gemological testing can tell them apart.

We sell natural and lab-grown diamonds.

Depending on your preferences, we will help you choose between the low price and availability of lab-grown diamonds and the rarity and historical significance of mined diamonds. The number of lab-grown diamonds is unlimited, whereas natural diamonds are rumored to be scarce. 

We supply lab-grown diamonds

Leon Mege is your one-stop shop for certified lab-grown diamonds at wholesale prices. Choosing a lab-grown diamond will afford you a better and larger stone, and they are getting more affordable with every passing day. 

For over 30 years, we have been using and promoting lab-grown diamonds. We are trendsetters pioneering the use of lab-grown diamonds in bespoke hand-forged jewelry. We offer IGI and GIA-certified eco-friendly lab diamonds of all shapes and sizes that are conflict-free, ethically sourced, and 100% recyclable.

Just when you thought your dream diamond was out of reach, the relentless technological progress brought us the Gorilla Glass Victus, Rimac C_Two car, polymer-framed Sig-Sauer handgun, and Peeps eyeglass cleaners.

How to tell the difference between natural and lab-grown

The lab-grown diamonds are authentic diamonds even a veteran gemologist cannot identify from those spit out by volcanos. Unlike lab-grown rubies and sapphires, synthetic diamonds don’t have tell-tale inclusions, just like in-vitro children cannot be told apart from children spawn through physical relationships. 

Lab-grown diamonds are NOT “imaginary” diamonds like simulants such as moissanite or CZ’s. Only technologically advanced and costly equipment gem labs use can separate one another. 

Are lab-grown diamonds ecologically clean?

No, this is a massive lie perpetrated by the lab-grown industry marketing lobby. The sellers of lab-grown diamonds label their products as “sustainable” or “eco-friendly” and accuse producers of natural diamonds of polluting the environment. Marketing lab-grown diamonds as ecologically clean is misleading. However, it does not diminish their value to the consumer.

The immense heat and diabolical pressure needed to produce a one-carat diamond are compared to the energy of a volcanic eruption. The energy required to synthesize a diamond can go as high as 1,000 kWh per carat, depending on the production method. That does not chime well with false claims about zero carbon footprint. In addition, most factories are located in countries with little regard for the environment.

The lab-grown industry despises the term “synthetic.” They insist on the term “lab-grown,” which invokes peaceful green pastures where diamonds are roaming free, fattening up on organically grown graphite. What causes more harm to nature, mining, or synthesizing, is a subject for debate.

Despite what the diamond industry says, the world is not running out of natural diamonds. The price of natural diamonds is kept artificially high by DeBeers. This monopoly has succeeded in controlling the diamond market for over two centuries.

DeBeers and Alrosa, the Russian diamond mining monopoly, keep the supply of raw material scarce and prices artificially high. DeBeers learned that diamonds are forever the hard way because every diamond ever found is still with us.

More and more diamonds are unearthed every day, and they do not age. An old diamond is indistinguishable from a newly found one. The price decline over the last decade is a warning sign of DeBeers losing its grip on the market.

The average mine removes 250 tons of earth, wastes 120 gallons of water, and emits 143 pounds of carbon dioxide to produce just one carat of diamonds. 

There are plenty of natural diamonds to satisfy human vanity until our civilization self-destructs. The only difference between natural and lab-grown diamonds boils down to their cost.

Natural diamonds are naturally pricier, and yet, for that same reason, they offer greater satisfaction than their human-made clones. It is all about how natural diamonds make you feel. Their high price is something of a self-fulfilling prophecy. When you pay very little for a lab-grown diamond, studies suggest, your experience is less enjoyable.

When you pay more for a natural diamond, you feel that you got something more valuable. So if your priority is a feeling of romance and tranquility, we recommend getting a natural diamond. But if you are a rational person without silly superstitions, go ahead, get the human-made diamond and save money to buy a mountain bike.

Visually and physically, lab-grown diamonds are identical to diamonds extracted from the ground. The crystal growth is induced by immense heat and pressure, similar to natural conditions and processes inside the earth. Layer by layer, carbon molecules are deposited on a diamond seed, and, in theory, it can grow to any size.

For practical purposes, their growth is limited because huge diamonds have no practical purposes. However, in the future, when there will be diamond doorknobs, diamond desk lamps, and even diamond windows, the ginormous lab-grown diamonds might become useful again.

In 1954 Howard Tracy Hall synthesized the first artificial diamond at the GE lab in Schenectady, NY. For that invention, he was rewarded with a $10 US savings bond. GE went on to make a fortune.

Initially, synthetic diamonds were used only as industrial abrasives. It took about 50 years to produce gem-quality material suitable for use in jewelry. Synthetic diamonds have been produced in various colors: yellow, blue, green, pink, red, purple, and more recently, colorless.

Researchers at the Mexico’s University of Nueva Leon near Monterrey found that Tequila, the country’s national drink,  produced a diamond film when heated under pressure. Google it if you don’t believe it.

We can imagine the rigorous scientific effort by the heroic researchers who probably took a lot of shots of  80% proof Tequila Blanco, which requires a short aging process. The late-night tests confirmed that the drink crystallized into a diamond-like structure. 

On the other hand, a breakthrough cancer drug created in Mexico from Corona beer turned out to be a hoax.

So-called Blue Nuance diamonds are some HPHT-grown diamonds with faint blue tint. Rarely found in nature,  the blue tint results from the element Boron impregnating the crystal structure. The HPHT process uses boron as a catalyst and helps clear the nitrogen.

Any noticeable tint, whether yellow, green, brown, or blue, can affect the diamond’s appearance and color grade. But unlike brown, gray, or yellow tints not mentioned in the lab report, the blue tint can be commented as “faint blue.” The bluish undertone typically lowers the color grade, which makes Blue Nuance diamonds more affordable. These stones often appear better because blue cancels out the yellow tint in stones below H in color.

HPHT is an acronym for High-Pressure High Temperature, which is a process of subjecting carbon fuel to extreme pressure and temperature in order to turn it into a diamond crystal.

CVD stands for Chemical Vapor Deposition, where superheated gas is used to stimulate and grow a small diamond “seed” crystal into a full-sized diamond.
