What Are Lab Grown Diamonds?

Lab Grown Diamonds are a wonderful way to purchase a much larger diamond at a fraction of the cost. At typically 1/3 to 1/4 the price of natural diamonds, these make an excellent affordable alternative. They are created in a man-made forge using a diamond seed and undergo a process that mirrors nature’s process of diamond formation.

They are not fakes or simulants, such as cubic zirconias. Though they are sometimes referred to as synthetic diamonds, this term is misleading and may be why many think lab-grown diamonds are not real. Simulants may only slightly resemble diamonds from far away, but under close inspection they have many different properties.

You’ve poured endless effort and care into your relationship, so let’s put that same effort into the ring that will help determine your future together.

Are They The Real Thing?

You’re probably wondering, “Come on, oven baked diamonds? Are these real?” Don’t worry, this is a very common question, and the answer is: yes. These are not cubic zirconia look-a-likes being passed off as synthetic alternatives. Lab grown diamonds are much different than simulants, and have much higher quality and attractive attributes. 

According to GIA Spokesman Stephen Morisseau, “Lab-grown diamonds have all the same physical and chemical properties of a mined diamond.”

The best part is that your diamond will be hand crafted right here in Denver, instead of in a factory. Every piece, diamond, and detail will be attended to with care and love, ensuring that the ring is everything you dreamt it would be.

How Are Lab Grown Diamonds Made?

When our lab grown diamonds are made, they can undergo one of two procedures — High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD). These lab processes replicate the methods nature uses to create diamonds. Using an atomic carbon seed from already existing diamonds, lab grown diamonds undergo the same process that nature utilizes, only it’s in a lab. 

After the diamond seeds are quite literally baked in ovens, they must be cut and polished, same as any diamond. HPHT and CVD systems are not new by any means. These tried and true methods have seen advancements in modern technology which have allowed refinement to perfection in the process.

After that, our expert designers work with you on every individual detail, down to the exact millimeter width of the band. After that, we do 3D imaging of your ring to show you it from every angle. Once we have approval, our designers will craft your ring. The average ring typically takes 2 to 4 weeks, but we do offer expedited services for those that need it faster.

High Pressure, High Temperature

HPHT, or High Pressure High Temperature, is just like the name says. In order to reach the incredible amount of pressures that occur naturally inside the earth’s mantle, this method can use one of several types of presses including belt, cubic, and split sphere (BARS) presses.

Seeds are exposed to temperatures reaching as high as 2700 degrees Fahrenheit and pressure up to 1.5 million pounds per sq. inch. That amount of pressure and heat helps simulate the conditions that traditional diamonds are created in, which means you’re getting the real thing.

Chemical Vapor Deposition

First hypothesized in 1952, most thought CVD, or Chemical Vapor Deposition, was foolish or a fraud because it appeared to break the 2nd law of thermodynamics. It was then expanded on in the 60s, experimented with and proven successful. The process has been improved and perfected over the past 80 years to produce brilliant man-made gems. 

While still very hot, CVD uses less heat than the HPHT approach. Temperatures in the chamber can reach a scorching 1500 degrees Fahrenheit. This makes a carbon gas mixture which is then ionized into plasma. The gas mixture is broken down and pure carbon accumulates to the crystallizing seed, which has the appearance of bread rising.

How Are They Certified & Graded?

In the world of diamonds, we use the 4 C’s to determine how a diamond should be graded. These 4 C’s stand for cut, clarity, color, and carat. You can find out more specifics about this below. For now, we’ll stick to the overview. 

Jewelers will choose one of several reputable grading labs to evaluate their diamonds. At these labs, gemologists independently examine each diamond to establish an individual score. These individual scores are then collected and considered for a final grade. In this way, the grading is fair and honest. 

It is not unusual for a diamond to receive a different score when examined a second time. This is because the scores are ultimately subject to the gemologists’ opinion. The Gemological Institute of America (GIA) is an extremely popular and widely trusted lab and have been using a D-to-Z scale since the early 1950s in order to color grade diamonds. If these grades are of importance to you, you and your jeweler should have an open conversation about the jeweler’s grading lab.


The Largest Inventory

Prices of these lab grown diamonds are generally around a quarter the price of a natural diamond. These diamond growing labs allow for a much shorter supply chain and are mainly the reason for such an affordable price. As more labs begin to grow diamonds and improve the techniques, the cost will continuously become more competitive.
