What are lab created diamonds?
Lab created diamonds (also called lab grown, man made, or synthetic diamonds) are chemically, optically and physically identical to earth-mined diamonds, but are more ethical, beautiful and affordable than any diamond we will ever get out of the earth. We're replicating the earth's natural process by crystallizing carbon in a modern-day lab environment into brilliant diamonds that are priced up to 40% less, and are free of any environmental or humanitarian concerns.
Are lab created diamonds real diamonds?
Yes! Lab created diamonds are real diamonds, identical in every way (but the price!) to earth-mined diamonds. Not to be confused with cubic zirconia, moissanite, or a "look-a-like" diamond, lab created diamonds are 100% pure crystallized carbon. Think of it as making ice in your modern-day freezer versus getting it from a glacier; both are frozen H2O regardless of the origin. We are crystalizing carbon into stunning rough diamonds that are then cut, polished and graded just like earth mined diamonds.

On average, MiaDonna’s grown diamonds are priced 20-40% less than an equivalent quality earth-mined diamond. However, just like with earth-mined diamonds, prices will vary based on the diamond’s 4C’s – cut, clarity, color, and carat.
The difference in price is because our supply chain is so much shorter. Earth-mined diamonds can travel to 5 countries and touch 20 hands before it reaches the end consumer, but our lab created diamonds go from our labs, to our casting house, to you.
To give you an example of pricing, a 1.0ct Round Cut Laboratory Grown Diamond, H/VS1 is approximately $3,300 versus an equivalent earth-mined diamond priced at approximately $4,600 or higher. Now you can get engaged, plus pay for your wedding and go on a honeymoon without starting your life together in debt. That’s the way it should be!
How are lab grown diamonds created?
Lab grown diamonds are made one of two ways - either through High-Pressure High-Temperature (HPHT), or through Chemical Vapor Deposition (CVD). The majority of MiaDonna’s diamonds are grown using CVD which has been the most successful in producing higher quality diamonds.
Scientists start the process of growing a MiaDonna diamond by cutting a small piece of carbon, known as a seed. It is placed in a low-pressure microwave chemical vapor deposition (CVD) chamber. Gases combine with electrical energy, which ignites a plasma ball. From there a cloud forms in the chamber and carbon molecules rain on the seed. Within six to 12 weeks, a sizeable rough diamond is formed. It is then cut, polished and graded by the same world-renowned labs that certify earth-mined diamonds.
Lab-Grown Diamonds are here to stay. They are real diamonds, available at a fraction of the cost, without the need for destructive mining or conflict.GQ MAGAZINE

choice for lab created diamonds?
We are the pioneers of the lab created diamond retail industry and have been selling directly to consumers since 2007. Our created diamonds are superior to not only earth-mined diamonds, but also other grown diamonds on the market today.
Superior to other lab created diamonds.
We are now seeing many lab created diamonds hitting the market that don’t measure up. We grow our diamonds in the world’s most technologically advanced laboratories that have a long-running and deep-rooted history with us. This means we can offer you the best selection of the finest diamonds at the most competitive price.
Superior to earth-mined diamonds.
Every MiaDonna lab created diamond is a Type IIA diamond. This is the purest form of diamond, making them harder and more brilliant than regular Type Ia diamonds, which make up 98% of diamonds mined from the earth.
Superior in ethics.
As the first lab created diamond company in America to be a Certified B Corporation, we have proven our commitment to not only meet, but exceed the highest standards in social and environmental performance. Every lab created diamond from MiaDonna is guaranteed conflict-free and sourced from highly sophisticated labs where they are created and cut in a controlled environment. But we go one step further; profits from every purchase at MiaDonna funds our foundation, The Greener Diamond, that empowers diamond mining communities to live a life outside of poverty and diamond mining.
Not all grown diamonds are created equal!

No. A lot of people think we can program the process to create a specific diamond grade and carat size that are the same each time, but we can’t. We are simply putting the right conditions together but then nature takes it from there. Just like with earth-mined diamonds, there will be variances in color, clarity and carat size.
MiaDonna laboratory-grown diamonds are indistinguishable from earth-mined diamonds, even under a microscope, according to the Gemological Institute of America.
Unlike earth-mined diamonds, our man-made diamonds are created without negatively harming native communities, society or the Earth. According to the 2014 Frost & Sullivan report, "lab-grown diamonds are seven times less impactful to the environment than mined diamonds, use significantly less resources and emit a fraction of the air pollution."
We can not speak to other companies’ lab grown diamonds, however, our grown diamonds are created in highly controlled and technologically advanced environments, where worker safety and welfare is a priority, by employees being paid a fair and competitive wage.
By not mining diamonds, we are preserving indigenous communities and the earth while protecting workers from unsafe and threatening conditions. MiaDonna goes one step further by using our profits to positively impact the lives and land that have been negatively affected by the diamond mining industry.
Buying an engagement ring or diamond, regardless of origin, with the intent to sell it in the future is not a good investment. Many traditional jewelers tell consumers that lab-created diamonds have little to no resale 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. Regardless of origin, either man-made or mined, all diamonds are priced using an internationally accepted pricing system. This system is known as the Rapaport pricing method. Resale values are based on a percentage of the rapaport pricing method.
Most people only think of just the 4’cs when judging the beauty of a diamond. However, there are also Types of diamonds. Type la, llb and Type IIA, llb. In the past, we haven't talked too much about the different types of diamonds because the superior Type ll has been unattainable to the majority of the population...until now!
98% of diamonds mined from the earth will be a Type la diamond. These are very common diamonds that you will find at your local jewelry store.
Only 2% of diamonds mined will be a Type IIA diamond, making them very rare. They are special because they contain the purest form of carbon, with either very little or no nitrogen atoms in the crystal structure. This makes Type IIA diamonds harder and brighter than common Type la diamonds. White diamonds are exceptionally colorless and colored diamonds are often found with a brown, purple, blue, or pink tone.
Previously, Type IIA diamonds were only owned by royalty and the super-wealthy due to their incredible beauty and high caliber. For example, The Elizabeth Taylor Diamond and The Hope Diamond are both Type IIA Diamonds. All of the diamonds we grow at MiaDonna are the superior Type IIa, giving you even more value for your money.
Chemical Vapor Deposition, or CVD, is a process used to create gem-grade diamonds as well as optics and semiconductors. The CVD process uses ultra-pure carbon-rich gasses in a controlled chamber. Carbon-based gasses, such as methane, are heated until they break apart allowing the carbon atoms within the gas to separate. These tiny carbon atoms fall onto a diamond substrate and build up layers resulting in a rough diamond crystal. This process takes between six to ten weeks and yields gem-grade Type IIa diamonds.
In recent years, CVD research has gained popularity and now modified versions of CVD are being used. These processes differ in the means by which chemical reactions are initiated. Some of these variations include:
- Low-pressure CVD (LPCVD)
- Ultrahigh vacuum CVD (UHVCVD)
- Plasma-enhanced chemical vapor deposition (PECVD)
- Microwave Plasma Vapor Deposition (MPCVD)
High-Pressure High-Temperature, or HPHT, recreates a diamond's natural growing environment found deep within the Earth. The machines used have the ability to build up the pressure of almost 60,000 atmospheres and temperature of 2,500 degrees Celsius.
The growth cell contains all the elements needed to grow a diamond, including a seed, highly refined graphite and a catalyst mixture consisting of metals and powders. The cell is placed in the center of the HPHT chamber. Consistent temperatures reaching 1,300 degrees Celsius and more than 50,000 atmospheres of pressure are applied. The catalysts inside the cell are the first to react to the added heat and pressure and change from solid to molten form.
The molten catalyst solution causes the graphite within the cell to dissolve. Once all the required conditions are met, the cooling process begins. This process takes place over several days and allows the carbon atoms to build upon the seed. The cell is removed from the HPHT machine once the growth cycle is complete. The new rough diamond is extracted and cleaned in preparation for final cutting and polishing.
The entire HPHT growing process requires an incredibly controlled environment to produce a gem-quality diamond. Any shift or change during growth can cause the diamond to stop growing or can create inclusions that result in unusable diamonds. Every diamond must complete the entire growth cycle before the machine can be opened. It is only after the HPHT chamber is opened that we can see the finished rough diamond and its color, clarity, and size.
Within the HPHT process, there are three primary tools used to supply the pressure and temperature necessary to produce lab-created diamonds. These are:
- Bars Press - The Bars Press is the most effective tool used for producing gem-quality diamonds. It uses a combination of inner and outer anvils to apply hydraulic pressure to the growth cell.
- Belt Press - The Belt Press is the founding technology behind growing diamonds. It can be large and produce several diamonds in only one cycle by using two large anvils that press together to create the necessary pressure. It is capable of producing gem-quality diamonds but is most commonly used to produce diamonds and diamond powder for industrial purposes.
- Cubic Press - A Cubic Press can be large in size and uses six separate anvils to create the necessary pressure for diamond crystal growth. It is also used to create diamond powder for industrial purposes.
MiaDonna lab created diamonds are available in a variety of trendy colors.
WHITE LAB-CREATED DIAMONDS
The most common diamonds are white diamonds and are graded on the lack of color present. White lab grown diamonds are 20%-40% less than their earth-mined equivalents.
YELLOW LAB-CREATED DIAMONDS
Both mined and lab grown diamonds get the yellow color from nitrogen. Once light enters the diamond, the nitrogen will reflect back yellow light. Yellow lab grown diamonds cost up to 75% less than their earth-mined equivalents.
BLUE LAB-CREATED DIAMONDS
Coming in colors ranging from fancy light blue to fancy intense blue, both mined and lab-created blue diamonds get their color from boron. Blue lab grown diamonds cost up to 90% less than their earth-mined equivalents.
PINK LAB-CREATED DIAMONDS
Earth-mined pink diamonds are the most rare color available and also the most expensive. Pink lab grown cost up to 95% less than their earth-mined equivalents.
