Lily Dia is built on love and legacy. Led by Jared and Brie, partners for over 12 years, we bring a deeply personal touch to the jewellery experience. With a family heritage in the industry spanning 25 years, we possess an instinctive eye for quality and an obsession with detail. We prioritize education and transparency, guiding you through the process without pressure. When you choose us, you work directly with people who pour their heart and soul into creating the best possible piece for your story.

You speak directly with the owners, Jared and Brie personally discuss every design to ensure it's perfect. We don't do mass production or generic pieces. Every ring starts from scratch based on your vision, with 3D CAD modeling and unlimited revisions until you're completely happy. We offer Natural Diamonds, Lab Diamonds, and Moissanite equally because each has its own beauty and appeals to different customers. We won't upsell you or push designs we can't execute flawlessly, we'll tell you no if something won't work. Jared travels yearly to major shows in Hong Kong, China, and India, building direct relationships with ethical suppliers. We maximize value through craft knowledge and global industry connections, not sales tactics.

Yes, we proudly offer a full spectrum of choices including Natural Diamonds, Lab-Grown Diamonds, and Moissanite. We believe every gemstone has its own unique beauty and story, and we don’t believe in limiting your options based on industry stigma. Our goal is to educate you on the differences so you can select the stone that perfectly aligns with your aesthetic, values, and budget.

We work primarily with high-quality, durable precious metals designed for lifetime wear. Our standard collection features solid 18k Yellow, White, and Rose Gold, as well as Platinum. However, because we are a custom jeweller, we are not limited to a catalogue. If you have a specific request for a different metal or alloy, we can discuss sourcing it to ensure your ring is exactly what you envision.

Yes, absolutely. Ethical sourcing is a personal commitment for us, not just a label. Jared personally travels internationally to attend trade shows and visit suppliers, building close, long-standing relationships with partners in India, China, Hong Kong, and beyond. We only work with suppliers we trust, those who maintain safe working environments, treat their staff with respect, and adhere to strict ethical standards.

Yes, customization is our speciality. We don’t just modify existing stock; we work with you to build your dream piece from scratch. Bring us your inspiration, whether it’s a mood board, a sketch, or a combination of different styles, and we will create a custom 3D design for you. We allow you to iterate and refine the design until it is exactly what you envisioned before we bring it to life.

Typically, our custom process takes between 4 to 8 weeks. This timeline ensures we can give every detail the attention it requires without rushing the craftsmanship. During peak seasons, this may extend slightly, but we prioritize transparency above all else. We will provide you with a clear, realistic completion date at the very start of the project and keep you updated throughout, so you are never left guessing.

Every ring is different, but to give you a real idea: settings typically range from $760 to $2,000 depending on the design complexity and metal, and lab-grown diamonds start from $1,300. As an example, we recently completed a 14k round solitaire with a lab-grown diamond for $2,700. Because we operate as a bespoke online studio without shopfront overheads, your budget goes further with us. We are always upfront about pricing from the first conversation. We also offer flexible payment plans to help spread the cost. Get in touch and we can set one up for you.

we have jewellers in both Melbourne, Australia, and Auckland, New Zealand. We take a global approach to materials, sourcing the finest diamonds and gemstones from trusted partners in India, China, Hong Kong, and the United States. We are also committed to sustainability, utilizing recycled gold whenever possible to minimize our environmental impact without compromising on quality.

Yes, we offer personalized virtual consultations. We understand that designing a ring is a collaboration, so we connect with you directly via email, phone, or video call. This allows us to discuss your inspiration, review CAD designs, and select stones with you, providing a deeply personal service from the comfort of your own home.

To ensure we can offer the highest quality stones and craftsmanship at the best possible value, we operate as an online-exclusive studio. We do not maintain a physical showroom, which allows us to avoid high retail markups and staff costs. Instead, we provide high-resolution photos and videos of your specific stones and designs, ensuring you have total confidence in every detail before your piece is finished.

Currently, we ship throughout Australia and New Zealand with secure, fully insured delivery. We are excited to announce that we will be expanding our shipping globally in 2026, making our bespoke pieces accessible to more people around the world. All orders are carefully packaged and tracked to ensure your jewellery arrives safely and on time.

Yes, every piece is protected by our Lifetime Warranty against manufacturing defects for as long as you own it. This covers faulty craftsmanship, loose settings due to construction issues, flawed metal finishes, and stone or setting problems present when received. Normal wear and tear, accidental damage, repairs by other jewellers, and loss or theft are not covered. We recommend annual professional inspections and insurance for additional peace of mind. Proof of purchase is required for all warranty claims, and the warranty applies only to the original purchaser.
