Elongated Cushion
Read Description Close Description
The elongated cushion is the soft, modern favourite of the moment — a rectangular cushion with gently rounded corners that looks larger on the finger than a square cushion or round of the same carat weight. It pairs the romantic glow of a cushion with the slimming line of an elongated shape. This collection brings together elongated cushion designs in moissanite, lab-grown diamond and natural diamond.
Elongated cushion designs from AU$1,650
A 1ct elongated cushion moissanite solitaire starts at AU$1,650 in 9K solid gold, with hidden halo and full-pavé variations higher. A diamond centre is available on every design — see our diamond engagement rings collection. Prefer a classic square outline? See our cushion cut collection.

Elongated cushion FAQ
Why is the elongated cushion so popular right now?
It combines vintage softness with a flattering, finger-lengthening shape, and it looks larger per carat than a round — a lot of value and presence for the budget.
Elongated cushion or oval?
Both elongate the finger. An oval has fully curved sides; an elongated cushion has soft corners and slightly larger facets for a warmer glow. Book a Melbourne appointment to compare.

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.
