FAQs: Everything You Need to Know About the Lab Grown Diamond Engagement Ring

What is a lab grown diamond, and how does it compare to a natural diamond?

A lab grown diamond is a real diamond that’s created in a high-tech laboratory rather than mined from the earth. Chemically, optically, and physically identical to natural diamonds, it offers the same sparkle, strength, and beauty. However, the key difference lies in origin—lab diamonds are a more sustainable and ethical choice, with a smaller environmental footprint. So, for couples seeking a modern love story rooted in conscious values, it’s the perfect match.

Is this lab diamond engagement ring certified?

Yes, it is IGI certified, which means the diamond has been graded by the International Gemological Institute. It’s evaluated based on the 4Cs—cut, colour, clarity, and carat weight. In fact, this specific diamond boasts a D colour and VVS2 clarity, making it one of the highest quality stones available. Therefore, you can be confident that you’re investing in a ring with verifiable excellence.

 

What is a radiant cut, and why is it ideal for engagement rings?

The radiant cut blends the best features of the emerald and round brilliant cuts. It’s rectangular with cropped corners and a dazzling facet pattern that maximises sparkle. Thanks to its shape and brilliance, the radiant cut offers a bold yet elegant look. Additionally, it tends to hide inclusions better than other cuts, making it a practical choice for larger carat stones.

Can I wear this engagement ring every day?

Absolutely. This ring is designed for daily wear. Crafted in 18kt white gold, it’s durable enough to withstand everyday life. Plus, the setting securely holds the centre diamond and hidden halo in place. Of course, like all fine jewellery, it’s best to remove it during heavy lifting, harsh cleaning, or gym workouts to protect its brilliance.

Can I customise this ring or design a matching wedding band?

Yes, customisation is one of our specialties. You can alter the diamond size, shape, or metal type (yellow, rose, or platinum). Furthermore, we offer bespoke matching wedding bands tailored to fit perfectly with your engagement ring. Simply book an appointment for a private consultation in our Sydney studio.

Is this ring suitable for proposals and special occasions?

Without a doubt. This lab grown diamond engagement ring is crafted to celebrate life’s biggest moments. With its breathtaking sparkle, ethical origin, and luxurious 18kt white gold setting, it’s a show-stopping choice for proposals, engagements, anniversaries, or vow renewals. Additionally, it comes beautifully packaged, ready for that perfect reveal. So, whether it’s your first “yes” or a renewal of forever, this ring will say it all.
