30 Best Moissanite Custom Jewellery Manufacturers in Australia
Moissanite has quietly become one of the most-requested gemstones in Australia. It carries more fire and brilliance than a diamond, costs a fraction of the price, is lab-created and conflict-free, and is hard-wearing enough (9.25 on the Mohs scale) for everyday wear. No surprise, then, that couples planning engagements and businesses launching jewellery lines are both hunting for the same thing: a maker who can turn an idea into a finished, custom moissanite piece.
This guide brings together the 30 best moissanite custom jewellery manufacturers serving the Australian market in 2026. It is written for two kinds of reader:
- Individuals and couples who want a one-of-a-kind moissanite ring, pendant, or set custom-made for them.
- Jewellery brands, retailers, boutiques, and e-commerce founders who need a manufacturing or wholesale partner to produce custom moissanite jewellery at scale.
We have grouped the list so you can jump straight to the type of maker you need, and we have added a full buyer’s guide at the end covering certification, cost, timeframes, and the questions worth asking before you commit.
How we chose this list?
There is no shortage of “best of” lists online that simply rank whoever paid the most or padded the page. We took a different approach. Every business below was assessed against criteria that genuinely matter when you are trusting someone to make a piece you’ll keep for life or to manufacture stock you’ll put your brand name on:
- Custom / made-to-order capability can they actually build to a brief, not just sell from a catalogue?
- Craftsmanship and finishing quality of setting, metalwork, and polish.
- Certification and transparency GRA / GRC certificates for moissanite, IGI / GIA where lab-grown diamonds are also offered, and recognised trade credentials.
- Service and aftercare warranties, resizing, consultations (in-person and virtual), and clear communication.
- Suitability for Australian buyers local presence, or fully insured shipping into Australia and the ability to work remotely.
- Ethics and sustainability recycled metals, responsible sourcing, and certified supply chains.

Moissanite buyer’s guide (for couples & individuals)
Is moissanite a good choice for an engagement ring?
Yes and in some practical ways it outperforms diamond. Moissanite is the second-hardest gem used in jewellery at 9.25 on the Mohs scale (only diamond is harder, at 10), so it stands up to daily wear. Its refractive index of 2.65 (versus 2.42 for diamond) gives it noticeably more “fire” that rainbow flash you see when the light moves. The trade-offs are resale value and the very top end of hardness, neither of which matters much for a ring you intend to keep.
Moissanite vs lab-grown diamond what’s the difference?
They’re both lab-created and ethical, but chemically different. Lab-grown diamonds are identical to mined diamonds and sit slightly higher on hardness; moissanite has more brilliance and fire and costs dramatically less often around 10% of an equivalent lab-grown diamond. The decision usually comes down to budget and the look you prefer. Many makers on this list sell both, so you can compare side by side.
How much does a custom moissanite piece cost in Australia?
As a rough guide from Australian makers in 2026, a 1-carat (≈6.5mm) moissanite solitaire in 14k gold starts from around AU$1,650, with halos and larger or platinum pieces rising from there. Entry-level moissanite rings can begin around AU$400, while complex bespoke pieces run into the AU$4,000–$5,000+ range. Price is driven by stone size, metal, setting complexity, and number of accent stones.
Certification: what to look for
- GRA / GRC the certificates most commonly issued for moissanite (colour, clarity, cut).
- IGI / GIA used where lab-grown or natural diamonds are also involved.
- Ask for a digital certificate of authenticity and an inscription where available. Reputable makers provide this as standard.
How long does a custom ring take?
Typically two to eight weeks depending on the maker and complexity, with many studios offering a three-week expressoption for proposal deadlines (sometimes for a fee). Expect a CAD render to approve before any metal is cut, and progress photos at key milestones from the better studios.
Five questions worth asking before you buy
- Is the ring solid metal (not plated), and is it hallmarked/stamped?
- What certification comes with the moissanite, and what colour/clarity grade?
- What does the warranty cover and is resizing or servicing included?
- Will I see and approve a CAD design before production?
- What’s the total timeframe, and is insured shipping included?
How to choose a moissanite manufacturing partner (for businesses)?
If you’re sourcing a manufacturer to produce a moissanite jewellery range rather than buying a single piece, the evaluation is different. Use this checklist when you speak to partners like Valentine Silver International, JewelPin, or any factory you’re considering:
- Capabilities & capacity can they handle your designs, metals (925 silver, 9–18k gold, platinum), and your volume now and as you grow?
- Design support do they offer a design bank, CAD, and ODM/OEM services, or only build to finished tech-packs?
- Stone sourcing & grades which moissanite grades and certifications can they supply, and can they set client-supplied stones?
- Minimum order quantities (MOQs) and sampling what’s the cost and lead time to get a first sample and a first production run?
- Certifications & ethics look for RJC certification, responsible-sourcing policies, and recognised sustainability credentials.
- Lead times & reliability typical production and shipping timelines into Australia, and how they handle re-orders.
- Compliance for the Australian market correct metal hallmarking/stamping and accurate product descriptions for Australian Consumer Law.
- Communication & samples responsiveness, English-language support, and willingness to iterate before bulk production.
Frequently asked questions
Who are the best moissanite custom jewellery manufacturers in Australia?
For custom finished pieces, leading Australian makers include Moi Moi, TMC Fine Jewellers, Cullen Jewellery, Temple & Grace, Novita Diamonds, Larsen Jewellery, and Cushla Whiting. For wholesale and white-label manufacturing for jewellery businesses, Valentine Silver International and JewelPin are strong partners, while Charles & Colvard remains the benchmark for premium moissanite stones.
Can I get moissanite jewellery custom-made and shipped anywhere in Australia?
Yes. Most makers on this list either have showrooms in major cities (Sydney, Melbourne, Brisbane, Perth, Adelaide) or design remotely and ship fully insured Australia-wide, with virtual consultations and CAD approval handled online.
Is moissanite real or fake?
Moissanite is a real gemstone (silicon carbide), first discovered in 1893. Because natural moissanite is extremely rare, the moissanite used in jewellery is lab-grown chemically and optically identical to the natural mineral. It is a genuine gemstone in its own right, not an imitation diamond.
Where can jewellery businesses manufacture custom moissanite jewellery for Australia?
Australian brands and retailers can work with dedicated manufacturing partners such as Valentine Silver International a Jaipur-based, RJC-certified manufacturer with 800+ artisans and a 70,000+ design bank that produces custom silver and gemstone jewellery for retailers worldwide, including OEM/ODM and white-label production.
Does moissanite go cloudy over time?
No. Moissanite keeps its brilliance and fire indefinitely. It can look dull if dirt builds up on or under the stone, but a simple clean (warm water, mild dish soap, soft brush) restores its sparkle.
The bottom line
Whether you’re a couple after a one-of-a-kind ring or a business building a collection, Australia’s moissanite market in 2026 is rich with talented makers.
