Frequently Asked Questions about Lab
Grown Diamonds

lab grown diamonds new york

Are Man-made, Synthetic, or Lab Grown Diamonds Real?

Lab-grown Diamonds are authentic and not counterfeit diamonds. These man-made diamonds contain 100% carbon and have the same chemical composition as that of earth mined diamonds. Lab-grown diamonds are created by recreating the conditions underneath the Earth that result in diamond growth: pressure, heat, & carbon.

These diamonds are not like the diamond simulants in the market like cubic zirconia, or moissanite.

Is a Cubic Zirconia (CZ) the Same Thing as a Lab Grown Diamonds?

Cubic Zirconia (CZ) does not contain carbon and, hence, is not at all similar to Lab-grown diamonds. CZ are quite weak in comparison to Lab-grown diamonds, as, performance and patterning do not match that of diamonds. It is very easy for a jeweler to differentiate between a diamond and a simulant of diamonds.

Is a Synthetic Diamond the Same Thing as a Lab Grown Diamonds?

No. Lab grown diamonds are chemically exactly the same as natural diamonds and they are not synthetic.

Can a Jeweler Tell That a Diamond is Lab Grown?

At first glance, the natural diamonds & lab diamonds look similar even to trained jewelers. Even some of the commonly used jeweler tools are not able to judge the difference between lab-grown or mined ones. The inexpensive diamond testing tools used by jewelers are not a good fit as they fail to precisely test whether the diamond is lab-grown or mined.

A proper tool to test diamonds would cost around USD 10K. The best technique, known as Photoluminescence Spectroscopy, involves each diamond to freeze at -320°F. The majority of jewelers do not keep these types of tools due to the cost & complexity involved.

Therefore, every lab diamond beyond 0.50 Carat is certified by non-profit organizations of Gemology inscribed with the microscopic laser. So, any jeweler with the use of a microscope get the distinctive ID of the diamond & search it on the global database & verify its type.

How Do You Grow a Lab Diamond? Thing as a Lab Grown Diamonds?

When the pressure, heat, and carbon are set to similar circumstances underneath the earth, a lab-grown diamond is formed. Two methods for this are:

  • HPHT (High Pressure-High Temperature)

  • CVD (Chemical Vapor Deposition)

  • American Gem Society (AGS)

Each of them is used for developing multiple sizes & ranges of diamonds.

How Long Does it Take to Grow a Diamond?

A 1-carat lab-grown diamond requires 7 to 10 days to grow, and for 3 carats it takes up to a month. Any attempt to speed up the process of growing diamonds leads to fractures in the crystal. Therefore, the speed limit for growing diamonds has to be followed.

Are Lab Diamonds Graded by Third Party Organizations?

Gemological laboratories like GIA, GCAKL, AGS, or IGI certifies almost all lab-grown diamonds over 0.50 ct. We suggest Lab-grown diamonds with certifications only.

Does GIA grade lab diamonds?

GIA grades lab-grown diamonds. LGDR, a digital-only detailed report is provided by GIA for lab-grown diamonds with an evaluation of 4C’s in-depth. The digital report contains a QR code directly linked to the educational webpage of GIA. To facilitate the purchase of lab-grown diamonds to consumers, GIA inscribes the report number on the diamond’s girdle.

Where are Lab Diamonds Grown?

Lab-grown diamonds are developed by scientists, engineers, gemmologists, and technicians around the globe. Some of the prominent countries doing it are: - Russia, US, France, Germany, UK, Ukraine, India, Singapore, Japan, Belgium.

Are Lab Diamonds Environmentally Superior to Earth-Mined Diamonds?

Producing lab-grown diamonds is a feasible practice with the abundance of carbon and other renewing energy’s. Natural mining of diamonds consumes huge energy in comparison to that of growing a diamond. According to a study, it takes 250 kW hrs of electric energy to mine a single carat diamond. This can power almost average US households for nine days or could even make a Tesla Model S run for more than 600 miles.
