Every stone we craft is a testament to the power of innovation — our lab grown diamonds are grown using the same chemical process that forms natural diamonds, resulting in the same hardness, and brilliance as natural diamonds. You get the same stunning qualities which are indistinguishable from a natural diamond without any unsustainable mining practises.
Our diamonds are IGI certified and handpicked by our master jewellers. We source for brilliant diamonds with the best qualities in their class and we only use diamonds graded VS1 clarity and F color & above. Our diamonds are set in high quality 18k gold which will not tarnish easily over time.
