How To Tell The Difference Between Lab Grown Diamonds And Natural Diamonds

How To Tell The Difference Between Lab Grown Diamonds And Natural Diamonds

Whether looking for an engagement ring, a new pair of earrings or the perfect pendant you may have noticed the phrase ‘lab grown’ popping up more and more in your search. Recently the popularity of lab grown diamonds has greatly increased but with that comes a host of questions: what is a lab grown diamond? And why should you consider this as an option?

We’re about to answer all of your burning questions, so you’re ready to make an informed decision on your next diamond purchase.

What is a lab grown diamond?

A lab grown diamond is a diamond that has been curated in a laboratory setting rather than naturally mined from the earth. The lab imitates the exact same pressure, temperature and chemical vapour deposition needed for a diamond to form, just in a controlled environment. The outcome is the exact same - a diamond that is 100% crystallised carbon. Therefore, the only difference is the diamonds origin.

A lab grown diamond is not to be confused with cubic zirconia, moissanite, or a ‘look-a-like’ diamond, all of which have completely different chemical compositions to an actual diamond. Lab grown diamonds are diamonds.

The advantages of buying a lab grown diamond

So what is the advantage of a lab grown diamond? one of the key reasons for choosing a lab grown diamond over a natural one is the price. As laboratory grown diamonds are more accessible and can be created on demand (unlike their natural counterpart) they often have a much lower price tag. This often allows you to choose a larger carat or higher quality diamond without increasing or going over your budget.
