How are lab diamonds made?
Lab grown diamonds, also known as man-made or lab created diamonds, are grown in controlled laboratory environments using advanced technologies that duplicate the growing conditions of diamonds produced in the earth.
Lab diamonds are made of the same optical and chemical properties as earth created diamonds. The sparkle is the same. The only difference is their origin.

frequently asked questions
Do lab diamonds test as real diamonds?
Yes, lab created diamonds will test positive on a diamond tester. Although grown by scientists in a lab instead of in the earth's crust, lab diamonds are absolutely real diamonds. They have the same chemical and optical properties as natural diamonds.
If you were to place lab diamond rings next to earth-created diamond rings, you would not be able to see a difference.
Expert gemologists cannot tell the difference between the two with the naked eye. A lab diamond can only be distinguished from mined diamonds using specialized equipment that can detect the minor differences in trace elements and crystal growth.

Are lab diamonds the same as moissanite?
No, moissanite is a different mineral and stone than lab created diamonds, with a completely different look and hardness rating.
We do not work with moissanite for our engagement rings. Our engagement rings are exclusively made with lab diamond center stones.

How are lab diamonds made in the lab? What are the CVD vs HPHT lab diamond growing methods?
There are two common methods for lab diamond creation and growing, High Pressure High Temperature (HPHT) and CVD (Chemical Vapor Deposition). CVD is a newer technology and the preferred process to produce a quality, genuine diamond.
Oui only uses lab diamonds that are grown using the CVD process.
It is generally considered to take about a month to grow a 1ct CVD diamond, although growth periods vary individually for each diamond.
Growing these diamonds requires a unique and innovative process that starts with a thin ‘seed’ diamond placed inside a chamber and subjected to high temperatures. Then, a carbon-rich gas mixture is introduced to the chamber. The gases are ionized to break down their molecular bonds, allowing the pure carbon to attach itself to the diamond seed. As the carbon builds up, it forms atomic bonds with the seed diamond, resulting in the growth of a new, larger diamond — identical to diamonds found in nature.
These are the stones we exclusively use for our lab grown diamond rings. We identify the most optimal stones from this grow method which are then used for our engagement rings

Do lab diamonds have value?
Just like earth-mined diamonds, their market value will vary over time. Since lab diamonds are a more recent introduction to the market, there is more uncertainty on future pricing, when compared to natural diamonds, which are a finite resource.
We value your ability to choose what matters most to you. When it comes to your diamond engagement ring, we encourage you to select the diamond that makes the most sense for your budget and preferences. Our aim for Oui is to provide an exceptional quality lab diamond engagement ring that fits your preferences and budget.

Can you insure lab diamond engagement rings?
Yes, just like a mined diamond, lab diamond rings can be insured. We are happy to provide our recommended insurance company for jewelry & engagement rings.
What is a Type IIa diamond?
All Oui lab grown diamonds are Type IIa and offered in D-H color grading.
A Type IIa diamond is considered to be the most chemically pure type of diamond, with exceptional optical transparency and making up less than 2% of naturally occurring diamonds.

Our necklaces and earrings with center stones are also made with lab-created diamonds.
All diamond pavé and diamonds that are not center stones are conflict-free, natural diamonds. If you would like only lab grown diamond pavé on your ring, please contact our customer service team so we can assist your request.

The cut of a diamond is what delivers its light and brilliance. The GIA evaluates a diamond's brightness, fire, scintillation, weight ratio, durability, polish, and symmetry to arrive at a diamond's cut grade. Visit our blog post to learn more about the 4Cs of diamonds.
Our lab grown diamonds are 'Excellent' cut, the highest cut grading a diamond can receive, and exclusively GIA-certified.

Rings
Total carat weight represents the total weight of all the diamonds set within the ring.
Diamond weights are approximate and will range slightly based on your ring size and/or the unique cut and shape of your specific eternity band. We strive to match each stone perfectly.
Earrings
Total carat weight represents the weight of the (2*) center stones plus the total diamond pavé used within the design.
Diamond pavé weights are approximate and will range slightly based on your ring size and/or the unique cut and shape of your specific center stone.
Each center stone diamond selected for our earrings is unique and hand cut. In order to meet our highest standards of diamond curation, you may receive a center stone diamond that carries a little extra carat weight. Center stones may fluctuate up to .05 carats more. Any fluctuations will always be ABOVE your selected carat weight, never under. For example, if you select .70 carats for your center stone, your stone will be anywhere between .70 to .75 carats.
*all earrings (unless specified) come in a set of two
