Difference between Lab-Grown Diamonds and Natural Diamonds
The Origin of Natural Diamonds: Nature’s Billion-Year Art
Diamonds have fascinated us for centuries, but these mesmerizing marvels have a formation process that is rather a test of patience. They are formed when carbon atoms bond about 1 to 3 billion years, 100-200 kilometers under the Earth’s surface, under extreme temperature and high pressure over billions of years. Volcanic eruptions bring closer to the Earth’s surface, where humans discover and mine them through large-scale excavation.
Formation of Natural Diamonds
Step 1- Deep Earth Carbon
The carbon atoms are present about 145 to 200 km beneath the Earth’s surface, where temperatures rise over 1,100 Celsius and the pressure is over 5 gigapascals (GPa) - which is over 50,000 times greater than Earth’s atmospheric pressure (1 atm = 101.3 kPa) .
Step 2- Crystallization under Extreme Conditions
The carbon atoms bond in a specific way under these conditions to create a solid crystal, that we know as diamond.
Step 3- Erupt Your Way Out!
When powerful volcanic eruptions occur, they propel these crystals upward, in some cases quite near the Earth’s surface. The crystals are found in a type of rock known as Kimberlite.
Step 4- Extraction through Mining
When they get closer to the surface, the diamonds are mined from kimberlite pipes or riverbeds.
Step 5- Cutting, Faceting and Grading
Once mined, the diamonds are then cut, shaped and polished by expert gem cutters. They are then sent to labs which will grade them for the four Cs- Cut, Colour, Clarity and Carat.

WHAT ARE LAB-GROWN DIAMONDS?
Lab-grown diamonds, which are also called artificial diamonds or man-made diamonds, are chemically, physically, and optically identical to natural diamonds. The only difference? Their origin.
Are Lab-Made Diamonds Real?
Wondering whether lab-grown diamonds are real? YES! They are 100% real diamonds. These diamonds are grown in controlled lab environments, using cutting-edge technology that replicates the Earth’s natural diamond-forming process.
How Are Lab-Grown Diamonds Made?
Curious how diamonds are made in a lab? Let us take a brief look at the process.
- Diamond Seed: The central base is just a sliver of a natural or lab diamond (it is referred to as a seed).
- Growth Chamber: The seed is then put in a high tech chamber in one of two ways: 1)HPHT (High Pressure, High Temperature), 2) CVD (Chemical Vapor Deposition)
- Carbon Crystallization: Carbon gas or graphite was added. Under the right conditions, the carbon atoms bond layn by layer forming a diamond crystal — the same exact way it happens in nature.
- Cutting & Polishing: The rough diamond is then cut and polished by a master gem cutter, similar to a mined diamond.
- Certification: Every lab-grown diamond comes with a certificate from top grading institutes such as IGI or GIA.
