Shop Engagement Rings by Carat
Read Description Close Description
Carat is weight, not width, and the two do not move together in a straight line. Doubling the carat does not double what you see on the hand. This page collects every size we make so you can compare them properly.
Face-up size at a glance
Round: 1ct about 6.5mm, 2ct about 8.1mm, 3ct about 9.3mm, 4ct about 10.2mm, 5ct about 11mm.
Oval: 1ct about 7 x 5mm, 2ct about 9 x 7mm, 3ct about 10 x 8mm, 4ct about 12 x 8mm, 5ct about 13 x 9mm.
Elongated shapes cover more finger than a round of the same weight, so an oval, pear or marquise wears larger than the number suggests. Sizes are quoted as diamond equivalent.
How to choose
Finger size changes everything. The same two carat stone reads generously on a size H and modestly on a size Q. Band width matters too, because a wider band makes a stone look smaller by comparison.
Shop by size: one carat, two carat, three carat, four carat, five carat.

GRC certified moissanite in D-E colour and VVS clarity, or an IGI certified lab grown diamond. 9k, 14k or 18k gold in white, yellow or rose, or platinum.

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 design consultation, by appointment, at our Melbourne studio in Southbank or via video call. Custom-made rings take up 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.
