LAB-GROWN DIAMONDS

Yes. A lab diamond will test positive on a diamond tester. Although created by scientists instead of in the earth’s crust, lab diamonds are absolutely real diamonds. They have the same chemical and optical properties as natural diamonds.

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 minor differences in trace elements and crystal growth.

No. Moissanite is a different mineral and stone than diamonds. Moissanite has an entirely different look and hardness rating.


Jean Dousset does not work with moissanite for any of our jewelry or engagement rings. We only select the top 1% of lab diamonds available worldwide.

Here are the two common methods for lab diamond creation and growth: 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.

Typically, it takes about a month to grow a 1ct CVD diamond, although growth periods vary individually for each diamond.

Growing lab 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. The gasses 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 a new, larger diamond that is identical to diamonds found in nature.

At Jean Dousset, all of our diamonds greater than 1 carat are grown using the CVD process.

We’re committed to helping you 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 preferences and your bank account.

Yes. Similar to a mined diamond, lab diamond rings can be insured. We recommend Jeweler’s Mutual where you can get a free jewelry insurance quote. Please contact us if you have any additional questions or need assistance.

All our lab diamonds are Type IIa with D-H color grading. A Type IIa diamond is considered to be the most chemically pure type of diamond in the world, with exceptional optical transparency. They make up less than 2% of mined diamonds.

Yes. Engagement rings are exclusively made with lab diamond center stones that you select from our digital diamond collection.

All diamond pavé and diamonds on your engagement ring that are not center stones are conflict-free, lab diamonds.

We do not sell mined diamonds but may be able to source something custom for you. Please reach out to our client services team for assistance.
