Lab-Grown Diamonds
What Are Lab-Grown Diamonds?
A lab-grown diamond is a real diamond. It has the same carbon structure, the same sparkle, and the same durability as one pulled from the earth. The only difference is where it was formed: in a laboratory rather than a mine.
These diamonds are graded for cut, clarity, colour and carat in exactly the same way as natural ones. Even jewellers need specialised equipment to tell them apart.
How Are They Made?
At Lab Rocks, all of our diamonds are created using the CVD (Chemical Vapour Deposition) process, the most advanced technique for growing diamonds today.
It begins with a thin slice of diamond, known as a seed, placed inside a sealed chamber. That chamber is filled with carbon-rich gases, which are heated until they turn into plasma. In this environment, carbon atoms are released and settle, one by one, onto the seed. Over time, the crystal grows layer by layer into a fully formed diamond.
Because the environment is carefully controlled, CVD diamonds often display exceptional clarity and brilliance, with fewer natural inclusions than many mined stones. The result is a diamond that is chemically, optically, and physically identical to one formed in the earth—just created in a cleaner, more sustainable way.
Why More Women Are Choosing Lab-Grown
For many women today, jewellery has to feel good as well as look good. A lab-grown diamond gives you both.
- They are conflict-free, with no connection to destructive mining practices.
- Their environmental impact is far lower than that of traditional diamond extraction.
- They are usually priced 30–40% below mined diamonds, allowing you to choose a larger or higher-quality stone.
- Because they are grown in controlled conditions, they often display remarkable clarity and brightness.
