LAB GROWN DIAMONDS ARE REAL DIAMONDS

The only difference between lab grown diamonds and natural diamonds is their origin. Lab grown diamonds are produced by scientists in a laboratory and natural diamonds are formed naturally beneath the Earth’s crust. 

Lab grown diamonds have identical chemical, physical and optical properties to natural diamonds.

Only an expert and a high-tech machine can tell the difference between a lab grown diamond and a natural diamond.

HOW LAB GROWN DIAMONDS ARE MADE 

There are currently two main methods for producing lab grown diamonds:
High pressure, high temperature (HPHT) and Chemical vapour deposition (CVD) method 

The CVD Method 

This method is quite different to natural diamond formation and is now becoming much more widespread. The process produces lab grown diamond from a heated, carefully controlled mixture of gases in a vacuum chamber at very low pressures. As the required, extreme temperature is reached, the gas molecules break apart and carbon atoms bond to the diamond seed crystals. The carbon atoms repeatedly attach themselves to the diamond seed, growing the lab grown diamond layer by layer. Production of gem-quality CVD lab grown diamonds takes only a few weeks. 

The HPHT Method 

This was the first commercially viable method for the creation of diamonds and is still the main production method in use worldwide. This process mimics the conditions under which natural diamonds develop when they form beneath the Earth’s crust. This method uses a central reaction cell surrounded by a large mechanical press, which is subjected to high pressures and temperatures. Inside the reaction cell, a diamond seed acts as a nucleus upon which the lab grown diamond crystal grows. Production of gem-quality lab grown diamond of a few carats can take only a few weeks. 

CREATED BRILLIANCE LAB GROWN DIAMONDS

All Created Brilliance lab grown diamonds are hand-selected and graded by the 4C’s (colour, clarity, cut and carat weight), in the same manner as natural diamonds.

To be a Created Brilliance lab grown diamond, diamonds must have a minimum colour and clarity of GH SI2-I1.

Each piece of Created Brilliance jewellery is accompanied by an authenticity certificate which guarantees your piece is lab grown diamond. 

WHY YOU SHOULD BUY
LAB GROWN DIAMONDS
 

Lab grown diamonds are more affordable than natural diamonds, which means you can buy a bigger and better quality diamond.

Lab grown diamonds are the conscious choice. Unlike with natural diamonds, no mining is required and so no land, wildlife or local communities are displaced and no conflicts are funded.
