Blythe - 0.99ct Natural Oval Diamond Halo Engagement Ring

Lab-grown and natural diamonds are chemically, physically, and optically identical — both are pure carbon with the same hardness and sparkle. The difference is origin and price: lab-grown typically costs 30–50% less, so you can go bigger or higher-quality for the same budget.

Lab-grown diamonds are certified by IGI; natural diamonds by GIA. Every stone is laser-inscribed and hand-selected by our team.

Every engagement ring can be customised — swap stone specs, switch lab-grown for natural, add a hidden gemstone, halo, engraving, or initials. If you can picture it, we can likely make it. Get in touch and we'll guide you through the options.

We offer flexible financing through ZIP, Afterpay, PayPal Pay in 4, Humm, and Latitude GEM Visa. In-store purchases can also be paid off with layby.

In-stock pieces are typically dispatched the next business day and arrive within a few days. Every parcel is tracked, registered, and insured.

You have 30 days to return your piece in its original condition, no questions asked.

Resizing typically takes around 10 days. There's no time limit on when you can bring a piece in to be resized from your original purchase date — though for the safety of your ring, we recommend resizing promptly to protect against accidental loss. We also offer one complimentary resize every 10 years, to allow for the way your fingers change over time.

Every diamond engagement ring, wedding band, or custom piece purchased for $2,000 or more comes with our Lifetime Diamond Guarantee — free repair or replacement for manufacturing faults, for life. It doesn't cover wear and tear, accidental damage, or loss. To stay eligible, bring your piece in for a complimentary inspection every 6 months, which includes a professional clean, polish, and security check (plus rhodium plating annually for white gold). This guarantee sits alongside your rights under Australian Consumer Law — it doesn't replace them. Full terms here.

We don't insure pieces directly, but we recommend Q Report and provide the documentation you'll need to get your piece covered.
