Lab Grown Diamond FAQs

1) Are these diamonds real?

Yes, they are as real as they come. Chemically, physically, and visually, these diamonds are exactly like natural diamonds.

Their beauty and sparkle are captivating, but they are a bit easy on the pockets which is the major reason behind their increasing popularity.

2) Are they certified?

Each of these diamonds comes with a quality certificate.

To your surprise, they are certified by the same reputed institutes that certify natural diamonds, the International Gemological Institute (IGI) and the Gemological Institute of America (GIA).

They are graded based on 4C’s, just as mined diamonds. Make sure to look for the quality certificate while buying lab-grown diamonds to get an idea of their value.

3) How are these diamonds grown?

There are two methods widely used to create diamonds in a laboratory.

1) High Pressure and High Temperature (HPHT)

This method mimics the natural procedure of growing a diamond. A carbon molecule is exposed to extreme degrees of heat and pressure to form a diamond in a laboratory.

2) Chemical Vapour Deposition (CVD)

This method yields better-quality diamonds. Here, the gases like methane and hydrogen are released in a vacuum chamber where a diamond seed is already placed.

This chamber is then heated to a high degree which causes the gas to form molecules around the seed.

Each diamond from the lab comes in its raw form, just like natural diamonds come from mine and then they are polished and cut to give that diamond shape.

4) Can everyone tell the difference between lab-created diamonds and natural diamonds?

No one can tell the difference between lab-grown diamonds and natural diamonds with the naked eye, not even some jewelers because of their similar structure, shine, and characteristics.

According to GIA, the differences between these man-made diamonds and naturally mined diamonds can only be detected by trained gemologists and high-graded equipment which are specially designed to distinguish them.

So, you need to watch them under a microscope to find the tiny laser mark on its girdle or send it to the laboratory to be sure.

5) What is the difference between lab-grown diamonds and mined diamonds?

The only valid difference is where they come from, natural diamonds are mined out of the earth’s mantle by digging it miles deep whereas, artificially developed diamonds are grown in a laboratory under a controlled environment.

6) Do these diamonds change their color over time?

No, lab-grown diamonds never fade or get cloudy, nor do they ever change their color.

The exposure to air and light does not affect them, they will always sparkle and shine forever just like natural diamonds.

In short, “Diamonds are Forever” be it natural or lab-grown.

7) How much time does it take to develop a diamond in a laboratory?

The time taken depends on the size, quality, and color you are looking for. But ideally, a 1-carat lab-grown diamond will probably take 7 to 18 days.

8) How much cheaper is a lab-grown diamond compared to a natural diamond?

The price of each diamond depends on its quality, but usually, the diamonds that are grown in labs are 30- 40% cheaper than mined diamonds of similar grading and quality.

This affordable pricing is because mined diamonds go through a larger supply chain and need more resources to procure.

You can get a bigger diamond for the amount you are willing to spend.

9) What determines the quality of these diamonds?

Like natural diamonds, these diamonds also get their certificate of quality based on 4C’s- color, clarity, cut, and carat.

The carat weight is the size of a diamond, the color defines the yellow hues in the diamond.

The cut defines how finely the diamond is shaped to let the light travel and bounce through it and clarity defines the number of imperfections in a diamond.

10) Are all lab-developed diamonds perfect or of the same quality?

“Each diamond is unique”, stands true even when we talk about diamonds that are created in labs.

Each diamond’s quality is determined based on its cut, color, carat, and clarity.

There is a different scale for each of the lab-grown characteristics. So, just like mined diamonds, each lab-grown diamond is valued on the grading it receives on each of these four scales.

11) Is buying them a sustainable choice?

These diamonds are for people who are concerned about how their choices impact the environment.

Not only are these diamonds worth buying because of their beauty but also because of their sustainability compared to natural diamonds.

Nature disruption, deforestation, and land pollution are several issues associated with the mining of natural diamonds.

On the other hand, these diamonds are created in laboratories, under controlled environments, and with limited resources.

12) Is it ethical to buy lab-grown diamonds?

Natural diamonds are often associated with terms like “blood diamond” or “conflict diamond” because the mining of natural diamonds has raised various humanitarian concerns like human rights violations and labor abuse.

People are becoming more aware of this and they do not want to promote such practices as they are not aligned with their ethical values.

There are no such concerns with these diamonds, as the process takes place in a systematic arrangement with full transparency to the consumer about its origin.

13) From where to buy these diamonds?

A very genuine question.

Always buy diamonds from a reputed seller and make sure to buy lab-grown diamonds from a seller who provides a quality certificate from a trusted institute.
