At Diamondrensu Australia, we’ve always known the truth—lab-grown diamonds are an incredible choice. Ethically created, visually stunning, and chemically identical to mined diamonds, they’ve been turning heads for all the right reasons. And now, the Gemological Institute of America (GIA) has made it official.
GIA has introduced a new, streamlined grading system for lab-grown diamonds—and it’s a game changer. Rather than applying the traditional 4Cs (cut, colour, clarity, carat) in detailed reports, GIA will now classify lab-grown diamonds as either Premium or Standard. Diamonds that don’t meet these high-quality benchmarks won’t be graded at all.
So, what does this mean for you?
It means that the lab-grown diamonds available through trusted retailers like Diamondrensu already meet consistently exceptional standards. The new grading system simply confirms what we already knew: lab-grown diamonds are reliably beautiful. They showcase excellent colour and clarity, brilliant sparkle, and incredible value—without compromise.
This change isn’t about lowering the bar—it’s about recognising how high the bar already is.
Choosing a lab-grown diamond has never been easier or more reassuring. With GIA’s backing, you can shop with confidence, knowing your diamond is the real deal—brilliant, ethical, and certified.
