Lab grown diamonds are real diamonds created in a controlled environment rather than mined from the earth. They offer the same brilliance, hardness and beauty as mined diamonds, often at a significantly lower price. This guide explains everything you need to know before you buy.
What Is a Lab Grown Diamond?
A lab grown diamond is made of pure carbon arranged in the same crystal structure as a mined diamond. It has the same chemical, physical and optical properties, and even trained gemologists need specialized equipment to tell the two apart. The US Federal Trade Commission recognizes lab grown diamonds as real diamonds.
How Are Lab Grown Diamonds Made?
There are two main methods:
- HPHT (High Pressure, High Temperature): recreates the intense pressure and heat deep inside the earth where natural diamonds form.
- CVD (Chemical Vapor Deposition): grows a diamond layer by layer from carbon-rich gas on a small diamond seed.
Both methods produce real diamonds. The growth method does not affect beauty or durability.
Understanding the 4Cs
Cut
Cut determines how well a diamond reflects light. It has the biggest impact on sparkle. Choose Excellent or Ideal cut for maximum brilliance.
Color
Diamond color is graded from D (colorless) to Z (light yellow). D to F are colorless, and G to H are near-colorless and look white to the eye, especially in yellow or rose gold.
Clarity
Clarity measures tiny internal features called inclusions. VS (Very Slightly Included) and VVS (Very Very Slightly Included) diamonds look completely clean to the naked eye.
Carat
Carat is a diamond's weight. Lab grown diamonds let you choose a larger carat weight for your budget than a mined diamond.
Jynora Lab Grown Diamond Quality
Every Jynora lab grown diamond meets the same high standard:
| Grade | Jynora Standard | What It Means |
|---|---|---|
| Color | E to F | Colorless, bright icy white |
| Clarity | VS to VVS | Eye-clean, no visible inclusions |
| Cut | Excellent | Maximum brilliance and sparkle |
| Certificate | IGI over 1 carat | Independently graded and verifiable |
Lab Grown vs Mined Diamonds
| Lab Grown Diamond | Mined Diamond | |
|---|---|---|
| Composition | Pure carbon | Pure carbon |
| Hardness (Mohs) | 10 | 10 |
| Appearance | Identical | Identical |
| Price | Significantly lower | Higher |
| Origin | Grown in a controlled environment | Mined from the earth |
IGI Certified Lab Grown Diamonds
Independent labs such as IGI (International Gemological Institute) grade lab grown diamonds using the same standards as mined diamonds. Every Jynora lab grown diamond over 1 carat comes with an IGI certificate confirming its cut, color, clarity and carat weight. You can verify your report number on the IGI website.

Lab Grown Diamond FAQs
Are lab grown diamonds real?
Yes. They are real diamonds with the same chemical, physical and optical properties as mined diamonds.
What quality are Jynora lab grown diamonds?
E to F color, VS to VVS clarity and an Excellent cut grade.
Are Jynora lab grown diamonds certified?
Yes. Lab grown diamonds over 1 carat come with an IGI certificate.
Can a jeweler tell a lab grown diamond from a mined one?
Not by eye. Specialized laboratory equipment is needed to identify a diamond's origin.
Do lab grown diamonds last forever?
Yes. With a hardness of 10 on the Mohs scale, lab grown diamonds are just as durable as mined diamonds and will not cloud or fade.
Why are lab grown diamonds less expensive?
They are produced through a shorter, more efficient supply chain without the costs of mining, so you pay for the diamond rather than the extraction.
Are lab grown diamonds a good choice for an engagement ring?
Yes. Their hardness makes them ideal for everyday wear, and they let you choose a larger or higher quality diamond for your budget.
