Lab Grown Diamonds

What is a Lab Grown diamond?

A Lab Grown diamond, is a diamond that is created in a laboratory setting through a process called chemical vapor deposition (CVD) or high-pressure high-temperature (HPHT) methods. These diamonds have the same chemical composition and crystal structure as natural diamonds, but they are manufactured under controlled conditions rather than being mined from the earth.

Are Lab Grown diamonds real diamonds?

Natural diamonds are formed deep within the earth over millions of years, whereas Lab Grown diamonds are created in a controlled environment in a matter of weeks or months.

How can you distinguish between Lab Grown and Natural diamonds?

For a naked eye it is impossible to distinguish between Lab Grown Diamond & Natural Diamond. Even trained and experienced gemologists cannot make out the difference.

There are third party gemological institutes like GIA, IGI, SGL, etc. which provide certification for diamonds and jewellery. These institutes are internationally recognised and are a go to for most jewellers and consumers.

Additionally, we only use Lab Grown diamonds which are laser-inscribed with a unique identification number which corresponds to a IGI or GIA certificate.
