Melbourne Lab Grown Diamond Rings

Moi Moi Fine Jewellery offers Melbourne's largest collection of lab grown diamond engagement rings at our luxurious Collins Street showroom, which opened in October 2022. Located at the Paris end of Collins Street (opposite The Block Arcade), our Melbourne store showcases an extensive range of lab grown diamond engagement rings and wedding bands. You can explore our collection seven days a week or book a personalized appointment with our diamond experts to find your perfect ring or create a custom design that reflects your unique style.

Moi Moi's Melbourne showroom stands apart through our specialised focus on lab grown diamonds and our exceptional selection—the largest in Melbourne. Unlike many Melbourne jewellers who offer primarily mined diamonds with limited lab grown options, we've pioneered the lab grown diamond market in Australia with over 20 years of expertise. Our Melbourne collection features only premium lab grown diamonds that have been carefully hand-selected by our team of experts, each accompanied by a comprehensive grading certificate. We also provide unparalleled education about lab grown diamonds, ensuring Melbourne customers make informed decisions with complete confidence in their purchase.

In our Melbourne showroom, lab grown diamonds typically cost 70-90% less than comparable mined diamonds, offering exceptional value without compromising on quality or beauty. This significant price advantage allows Melbourne couples to either save substantially on their engagement ring or select a larger, higher-quality diamond within the same budget. For example, a 1-carat lab grown diamond engagement ring that would cost approximately $8,000-$10,000 with a mined diamond might be available for $1,000 with a lab grown diamond of identical specifications. This value proposition has made lab grown diamonds increasingly popular among savvy Melbourne couples who appreciate both the ethical benefits and the financial advantages.

No, you cannot visually distinguish between lab grown and mined diamonds in our Melbourne showroom—or anywhere else—because they are physically, chemically, and optically identical. Even professional gemologists cannot tell them apart without specialised equipment. When you visit our Collins Street location, our experts can show you lab grown diamonds of various qualities, cuts, and sizes, but the distinction from mined diamonds lies in their origin and price, not their appearance or properties. Both lab grown and mined diamonds display the same brilliance, fire, and scintillation, and both will last forever with proper care.

Yes, our Melbourne showroom specialises in custom-designed lab grown diamond engagement rings, allowing you to create a truly unique piece. Our in-house design team works closely with Melbourne clients to bring their vision to life, whether that involves creating something completely original or modifying an existing design. The custom design process begins with a consultation at our Collins Street location, where we discuss your preferences, budget, and timeline. We then create detailed renderings for your approval before crafting your ring with the same exceptional attention to detail that defines all Moi Moi pieces. Many Melbourne couples appreciate this opportunity to participate in creating a meaningful symbol of their relationship that perfectly reflects their personal style.

Our Melbourne showroom offers flexible payment options to make your lab grown diamond purchase as convenient as possible. We accept all major credit cards and direct bank transfers for qualified purchases. For engagement rings and higher-value items, we also offer layby plans that are interest-free that allow you to secure your chosen piece with a deposit and make regular payments over an agreed period. Our Melbourne team can explain all available payment options during your visit and help you select the approach that best suits your needs.
