Ever wondered how lab-grown diamonds are made? Let's break it down. Lab-grown diamonds are created in advanced laboratories that replicate the natural conditions under which diamonds form deep within the Earth.
Using methods such as Chemical Vapour Deposition (CVD) and High Pressure High Temperature (HPHT), carbon atoms are crystallised around a diamond seed, allowing a diamond to grow over several weeks. The result is a diamond that is chemically, physically, and optically identical to a mined diamond, with the same brilliance and hardness.
The only difference is their origin... and a more accessible price point.
Sourcing Rare Diamond Cuts
While modern cuts such as round, oval, and emerald can be more readily available, antique-inspired cuts or less common styles such as yellow or champagne diamonds may take longer to source.
These diamonds often require more specialised techniques which mean it can be less commonly produced. In some cases, they are custom cut to achieve the desired proportions and character, resulting in a truly unique diamond.
