The round brilliant is the most enduring engagement ring cut there is — 58 precision facets engineered to return the maximum amount of light to the eye. It suits every hand, pairs cleanly with any wedding band, and never looks dated. This collection brings together round designs in moissanite, lab-grown diamond and natural diamond, from classic solitaires to hidden halo and pavé settings.

Round cut designs from AU$1,650

A classic 1ct round moissanite solitaire starts at AU$1,650 in 9K solid gold. Half-pavé bands, hidden halos and trilogy designs run AU$1,750–$2,150.

Round cut engagement ring FAQ

Why choose a round cut?
The round brilliant returns more light and fire than any other cut, hides inclusions well, and works with every setting style and band shape. It is the safest choice if you are unsure of your partner's taste.

How big does a 1ct round look?
A 1ct round moissanite measures about 6.5mm across and suits finger sizes 5–7. If you want more presence, step up to 1.5ct (7.5mm) or 2ct (8mm) using our ring builder.

Moissanite or diamond for a round cut?
Both are excellent. Moissanite offers more fire at a lower price; diamond holds stronger long-term value. Read our moissanite vs diamond guide to compare. Browse the round designs below, or book a Melbourne showroom appointment to compare carat sizes in person.

Frequently Asked Questions About Moissanite Engagement Rings

Q1: What is the difference between moissanite and a real diamond?

A: Moissanite is a lab-grown gemstone with brilliance, fire, and clarity that rivals a natural diamond. Side by side, most people cannot tell them apart visually. Three differences worth knowing: moissanite throws slightly more fire (rainbow flashes) than a diamond because of its higher refractive index; it scores 9.25 on the Mohs hardness scale (a natural diamond is 10); and it costs around 10% of an equivalent-size diamond. Every moissanite we set is lab-grown, conflict-free, and traceable.

Q2: Will my moissanite engagement ring look like a real diamond?

A: Yes. Today's moissanite is engineered to be near-colourless and exceptionally clear, and to the naked eye it is virtually indistinguishable from a diamond. Even jewellers usually need specialised testing equipment to tell them apart. The most obvious difference is actually MORE sparkle — moissanite has a higher refractive index than diamond, so it can throw slightly more colourful flashes in bright light. Most people who notice the difference do so because the ring sparkles more, not less.

Q3: Can I customise the metal, stone size, or setting?

A: Yes — almost every ring in our collection can be customised. Choose 9k, 14k, or 18k gold (white, yellow, or rose), or platinum. Centre stones range from 1ct to 8ct as standard, with larger sizes available on request. Settings include solitaire, bezel, halo, hidden halo, three-stone, and accent-stone designs. For fully bespoke work, book a free consultation at our Melbourne studio in Southbank or via video call. Custom-made rings take 4 to 6 weeks to complete.

Q4: Is moissanite durable enough for everyday wear?

A: Absolutely. Moissanite scores 9.25 on the Mohs hardness scale — second only to diamond (10) — which makes it one of the hardest gemstones you can wear every day. It resists scratching, chipping, and clouding, and unlike many gemstones it will not lose its brilliance over time. Every ring we make comes with a lifetime warranty on the centre stone, so if anything ever happens we will repair or replace it.

Q5: How do I care for my moissanite engagement ring?

A: Caring for moissanite is straightforward. Clean it once a week with warm soapy water and a soft toothbrush, then dry with a lint-free cloth — this keeps it as brilliant as the day you collected it. Avoid wearing your ring during heavy gym sessions, swimming in chlorinated pools, or when using harsh chemicals (gardening or cleaning). Bring it in for a free professional clean and inspection every 6 to 12 months — included in our lifetime warranty.
