The enlargement of diamond options available in the market today has driven many consumers to question, “What is a lab created diamonds?” In the simplest sense, Synthetic diamonds are diamonds that have been grown in a lab instead of being mined from the earth. They are chemically and optically identical to natural diamonds and are graded with the same scale. The FTC (Federal Trade Commission) recently amended their Jewelry Guides to rule that anything chemically identical to a mined diamond, is in fact, a diamond. So, Synthetic diamonds are diamonds – it’s as easy as that.
To fully understand what Synthetic diamonds are, it’s helpful to know the details of their composition and how they’re made. Just like natural diamonds from the earth, lab grown diamonds are made of carbon. Naturally, diamonds are formed under extreme heat and pressure over millions of years in the earth’s mantle. In a lab, lab created diamonds are formed under those same conditions, only with the help of innovative technology. The result, both mined and lab, is a crystallized carbon structure.(HPHT diamond, Diamond alternatives guide)
Another comparison point of lab grown diamonds vs. real diamonds is quality across many optical factors. Also similar to mined diamonds, lab created diamonds are graded by IGI (International Gemological Institute) Gemologists. Every stone is graded on the 4Cs of Diamond Quality: Cut, Color, Clarity, and Carat Weight. Each stone, lab, or mined, will come out unique. Due to this, the price of a diamond will vary depending on how well it performs in each of these categories.
Even though their source may be different, lab created diamonds and natural diamonds are chemically and optically the equivalent. This is great for consumers not only because it presents alternatives when buying engagement rings or diamond jewelry, but there are also a number of other positive benefits associated with Synthetic diamond.
THE ADVANTAGE OF LAB GROWN DIAMONDS
One of the most significant advantages of lab grown diamonds – and a reason why many consumers choose lab created – is their ethical and environmental efficiency.
Unlike mined diamonds, lab created diamonds have a minimal environmental impact. It takes considerably less energy to grow diamonds in a lab than it does to mine them from the earth. A one-carat mined diamond costs the planet between 88,000 and 176,000 pounds of displaced earth*. In contrast, each Synthetic diamond can save the planet that much alone in displaced earth, plus the energy needed to move it.

Synthetic diamonds are also produced in a much more ethical environment than the blood diamond trade. Mining conditions can be horrendous for workers, and are sometimes even akin to slave labor. On the other hand, companies who produce lab created diamonds do not engage in any sort of diamond mining to create the stones, so do not support or participate in these unethical practices. This means you can be sure that you aren’t supporting child labor or conflict diamonds when buying lab created diamonds.
In addition, another major benefit of Synthetic diamond is that they may cost significantly less than their mined counterparts. Although the cost of lab stones fluctuates, the average Synthetic diamond is around 20-40% less than a mined diamond. This makes the consideration of how much to spend on an engagement ring or other piece of diamond jewelry much more approachable because of affordability of these options.
Lab created diamonds are a less expensive, environmentally, and ethically superior choice. With these advantages, there really is no need to buy a mined stone, ever.
ABOUT DIAMOND ALTERNATIVES
Synthetic Diamond alternatives, also known as stimulants, are anything that contains similar characteristics but is chemically different than natural diamonds. They have recently grown in popularity across engagement ring trends, especially since there are many alternatives available in the market, all of which vary in physical and optical features. Some have such similar qualities that it is almost impossible to tell the difference by the naked eye.
Aside from the chemical composition, another differentiating factor of diamond simulants is how they are measured or qualified. Simulants are not all graded on the same 4Cs scale like diamonds and lab diamonds are. However, they are all graded based on the same hardness scale. This is called the Mohs scale, which rates stones from softest (1) to hardest (10). The closer a stone is to a perfect rating (10), the more durable and likely it is to last through the everyday wear of diamond engagement ring or piece of fine jewelry. All diamonds and HPHT diamonds rate a 10 on the Mohs scale.
THE BENEFITS OF DIAMOND ALTERNATIVES
Diamond alternatives feature many of the same benefits as HPHT diamonds, as they are more cost-efficient and environmentally friendly.
The majority of alternative stones are much less expensive than their mined counterparts (diamonds as well as gemstones). Since each stone is so different, it’s hard to pinpoint an exact range, but some, like New Grown Diamond alternatives, may be up to 80% less than mined diamonds. The exact cost estimate will depend on which alternative diamonds or gems you prefer and from which company.
Diamond alternatives are not only much less expensive, but they also have great environmental and ethical benefits, similar to Synthetic diamonds. Similar to Synthetic diamonds, the production of diamond simulants does not require the displacement of the thousands of pounds of earth needed to find a blood diamond. There is also no chemical runoff from strip mining, which destroys sea habitats for generations. Environmental concerns are almost completely eliminated with alternative stones.
DIAMOND ALTERNATIVES COMPARED
If you are deciding which stone to purchase, whether when picking an engagement ring or another piece of fine jewelry, weigh your options across the seven most popular diamond alternatives.
THE NEW GROWN DIAMOND ALTERNATIVE
The New Grown Diamond is a simulant stone that most closely resembles the same physical and optical characteristics of a perfect natural diamond. It is IF rated (internally flawless), G color (colorless), and Ideal Cut for maximum brilliance and fire. Moreover, unlike a mined diamond, it is guaranteed to never chip, crack or discolor, making it an heirloom quality stone that will last a lifetime.
The New Grown Diamond is made of a proprietary substrate and patented coating material that results in a heavier, harder, and more durable alternative stone. It rates a 9.1 to 9.2 on the Mohs scale. In relation to brilliance, the coating material disperses light at a much closer rate to a natural diamond, resulting in the perfect amount of sparkle.
The New Grown Diamond Is the highest quality alternative stone relative to price. It costs up to 80% less than a mined diamond while keeping all of the qualities that make a perfect diamond so captivating.
Cubic zirconia (CZ) is one of the most recognized alternative stones, commonly sold in inexpensive jewelry. Though, there is a big dispute between cubic zirconia and Synthetic diamond or natural diamonds. Although a well-cut CZ may look fairly close to a natural diamond at first, it is very porous, which results in the absorption of contaminants. Eventually, a CZ will become discolored and dull over time.
CZ is made of zirconia dioxide, which disperses light at a much higher rate than a diamond. This is responsible for the “fire” of a stone and will sparkle more than a diamond, sometimes resulting in flashes of rainbow color. It also has a lower refractory index, meaning it does not capture light in the same way a diamond does.
Cubic zirconium is softer than a diamond. It rates an 8 on the Mohs scale, which may cause it to chip or crack much more easily. CZ might be a good choice for an inexpensive set of earrings, but will not hold up for the everyday wear of an engagement ring.
Moissanite is made of silicon carbide and is also a very common alternative stone used in inexpensive jewelry. Natural moissanite is extremely rare, so most stones of this category that you come in contact with are lab created.
There is a large market for these simulants in jewelry, although their characteristics are far from those of a natural diamond. Due to moissanite’s high amount of brilliance and light dispersion, it produces a “disco ball” like sparkle. This means it is extremely sparkly and commonly reflects rainbow light.
In comparison to CZ, moissanite is a harder stone and much more comparable to a diamond. It rates a 9.2 on the Mohs scale, so it’s less likely to chip or crack during daily wear. It may be durable enough to be set in an engagement ring, but it won’t visually match the look of a diamond.
Morganite is made of the mineral beryl, and has an orange or pink tint. It can be found in nature or grown in a lab to have the same chemical and optical properties. Many stones are treated to improve color, which diminishes any orange or brass colors and results in a perfect pink stone.
Morganite has a much lower refractory index than a diamond and even CZ, so light is not captured in the same way. This does not mean it doesn’t reflect sparkle, merely that it will shine light in a different manner.
Although its characteristics are different than a colorless diamond, some brides opt for morganite for a non-traditional center stone or accents. It’s rated a 7.5 to 8 on the Mohs scale, meaning it has about the same durability as a CZ. Due to its low hardness rating and refractory index, morganite is one of the lowest performing alternative stones.
Rubies are made of the mineral corundum, making them a member of the larger corundum family. In a pure form, corundum is colorless, but due to trace elements of chromium, the color can range from light red to dark red. Rubies are also commonly grown in a lab to have the same chemical and physical properties, but without color variation. So unlike their natural form, a lab ruby will turn out an excellent deep red.
Rubies disperse light at a lower rate than diamonds, so they do not sparkle as brilliantly as diamonds. Instead, their deep red color is what makes them stand out.
Rubies rate a 9 on the Mohs scale, so they’re much more durable than other alternative stones, like moissanite. They are an excellent choice for engagement rings or fine jewelry, and can easily perform as an heirloom piece.
Like rubies, sapphires are also part of the corundum family. They are formed naturally, but can also be grown in a lab to have the same chemical, physical and optical properties. Just like rubies, their lab grown form will have no color variation, so they will be the perfect dark blue every time.
Sapphires also do not disperse light at the same rate as diamonds but are chosen because of their bold and mesmerizing hue. Sapphires are often used as side stones or surrounded by a halo of colorless stones to create balance and add sparkle.
Sapphires rate a 9 on the Mohs scale, so they are great for special pieces needed to last a long time or handed down for generations. Recently, their unique characteristics have caused them to grow in popularity, and they are now commonly seen in non-traditional engagement rings.
Amethyst is a purple variety of quartz that also can be found in nature or be produced in a gemological lab. Amethyst was used as a gemstone in many ancient cultures and is still frequently used today in birthstone jewelry and cocktail rings. Although they were once a prized, expensive gem, the stone is are now one of the most inexpensive alternative options.
Amethyst is softer than many other alternatives, even CZ, as it rates only a 7 on the Mohs scale. It won’t be the most dependable for long term wear or an heirloom piece like an engagement ring.
THE DIFFERENCE BETWEEN LAB DIAMONDS AND DIAMOND ALTERNATIVES
However, since different diamond alternatives vary so greatly, it is difficult to make direct comparisons between alternatives. The main takeaway is that lab diamonds are compositionally the same as mined diamonds and diamond alternatives are not.
