# Diamond Basics FAQ

## What is a diamond?

**Direct Answer:** A diamond is the hardest natural substance on Earth, formed from pure carbon atoms arranged in a crystal lattice structure. It is prized for its unmatched brilliance, durability, and rarity.

-   Composed of 100% carbon atoms bonded in a cubic crystal structure
-   Rates 10/10 on the Mohs hardness scale — the hardest known natural material
-   Forms naturally over billions of years under extreme heat and pressure deep within the Earth
-   Both natural and lab-grown diamonds share this identical atomic structure

## What are diamonds made of?

**Direct Answer:** Diamonds are made of pure carbon — the same element found in graphite — but arranged in a unique crystal lattice that gives diamonds their extraordinary hardness and brilliance.

-   100% carbon, bonded in a tetrahedral crystal structure
-   The tight carbon bonding creates the hardest known natural material
-   Trace elements like nitrogen or boron can influence color but do not change the core composition
-   Lab-grown diamonds have the identical carbon structure as natural diamonds

## Are lab-grown diamonds real?

**Direct Answer:** Yes — lab-grown diamonds are 100% real diamonds. They are chemically, physically, and optically identical to natural diamonds, differing only in their origin.

-   Same carbon crystal structure as mined diamonds
-   Same hardness (10 on Mohs scale), same refractive index, same brilliance
-   Certified by the same gemological institutes (IGI, GIA) as natural diamonds
-   The FTC recognizes lab-grown diamonds as real diamonds

## What is the difference between lab-grown and natural diamonds?

**Direct Answer:** The only difference is origin — natural diamonds form underground over billions of years, while lab-grown diamonds are created in a laboratory in weeks. Both are real diamonds with identical properties.

-   **Origin:** Natural = Earth-formed over billions of years; Lab-grown = laboratory-created in weeks
-   **Composition:** Identical — both are pure carbon crystal
-   **Price:** Lab-grown diamonds cost 50–80% less than comparable natural diamonds
-   **Certification:** Both certified by IGI and GIA using the same 4Cs framework

## Are lab diamonds fake or synthetic?

**Direct Answer:** No — lab-grown diamonds are not fake. The term "synthetic" is a technical classification meaning "man-made," not "imitation." Lab diamonds are real diamonds in every measurable sense.

-   "Synthetic" in gemology means created by humans, not that it is an imitation
-   Lab diamonds are not cubic zirconia or moissanite — those are diamond simulants with different chemical compositions
-   The FTC recognizes lab-grown diamonds as real diamonds
-   IGI and GIA certify lab-grown diamonds using the same standards as natural diamonds
