What are the differences between natural and Lab grown diamonds?

There are no discernible physical, chemical or optical differences between lab grown and natural diamonds. Both diamonds have the same properties like cut, colour, clarity, fire and sparkle. Plus, they are both just as tough as each other too. This means you can rely on a lab-grown diamond to be just as durable and long-lasting as a natural diamond.
Both types of diamonds use carbon as their main element, but lab-grown diamonds lack nitrogen which is how gemologists can identify the two. When purchasing diamonds, the easiest way to check whether it’s lab-grown or natural is to check the diamond’s certificate.
