Celebrating 15 Years of Parker Diamonds
“The true measure of our work is not simply in the beauty of a finished piece, but in the stories it becomes part of. Our greatest privilege is creating exceptional jewellery that will be treasured for a lifetime, and for generations to come.”
— Kim Parker, Co-Founder
What are the biggest mistakes people make when choosing an engagement ring?
Kim
One of the biggest mistakes is choosing a ring based purely on how it looks today, without considering how it will be worn for years to come. Practicality, metal colour and how it will sit alongside a wedding band are all important. We generally recommend an engagement ring height of around 7mm to allow a wedding band to sit neatly alongside it. I also always recommend choosing a certified diamond, giving you confidence in exactly what you're purchasing.
Mike
One common misconception is that carat determines how large a diamond looks. Carat measures weight, and two diamonds of the same carat weight can appear quite different depending on their proportions and cut. The highest colour or clarity grade doesn't automatically mean it's the best diamond either. What matters is the overall balance of beauty, performance and value.
For someone beginning the custom ring journey, what should they consider before booking an appointment with a jeweller?
Kim
Start with the fundamentals: agree on a budget and consider whether you're looking for a natural or lab-grown diamond. It's also worth discussing how involved your partner would like to be. Many couples attend the initial consultation together before one partner takes over to keep the proposal a surprise.
Mike
Timing is important. A custom engagement ring typically takes 6-8 weeks, so I recommend beginning your research 8-12 weeks before you'd like the ring completed, particularly if you're planning around travel or a significant date. You also don't need to have every decision made beforehand, that's what the custom process is there to help with.
How much should someone realistically budget for a custom engagement ring, and can a bespoke ring be created across different price points?
There isn't a universal budget for a custom engagement ring. The right investment is one that feels comfortable for you. Because every ring is designed from the diamond up, the stone, setting and overall design can be tailored to a wide range of budgets. Lab-grown diamonds have also expanded what's possible, giving clients greater flexibility to prioritise the features that matter most to them.

Design Consultation
We begin with a complimentary in-person or virtual consultation, guiding you through the diamond and design options. Once approved, we create a 3D CAD model so you can visualise the ring.

Diamond Sourcing
We hand-select exceptional GIA-certified natural and lab-grown diamonds and coloured gemstones to suit your style, vision and budget.

Craftsmanship
The ring is cast in precious metal and crafted by our Melbourne artisans before each diamond is expertly set to maximise brilliance.

Final Polish
Every ring receives a final polish and thorough quality check before it's ready to be collected and cherished.
Why does choosing a custom engagement ring often result in a more meaningful piece?
Kim
A custom engagement ring reflects the person who will wear it. Every decision, from the diamond and metal to the finer details, is made with them in mind. Those personal choices create a connection that isn't possible in quite the same way with an off-the-shelf piece.
Mike
An engagement ring is worn every day for a lifetime, so it should feel considered from every angle. A bespoke process gives you the freedom to make thoughtful choices about the proportions, setting and finer details, resulting in a ring that feels truly personal.
Parker Diamonds educates clients on the 7 Cs. What are they and why do they matter?
Alongside the traditional 4 Cs - cut, carat, clarity and colour - we consider Certification, Credibility and Confidence.
Certification provides an independent assessment of a diamond's authenticity and quality. Credibility is about trusting the people you're dealing with and knowing they have your best interests at heart. Confidence comes from having expert guidance throughout the process, so you can feel assured in your diamond and design choices.
How do you help clients decide between natural and lab-grown diamonds?
Our role is to explain the differences rather than steer clients in one direction. Natural diamonds are formed over millions of years beneath the earth, while lab-grown diamonds are created under controlled conditions. Both have the same chemical composition and appearance.
For some, the appeal of a natural diamond lies in its geological history, while others value the flexibility and accessibility of lab-grown diamonds. The right choice ultimately comes down to individual preferences and budget.
What are some of the biggest engagement ring trends you're seeing in 2026?
We're seeing a move towards designs that balance timelessness with greater visual impact. Oval solitaires remain a favourite, while elongated cushions, old mine cuts, marquise diamonds and trilogy settings are gaining momentum.
Clients are also becoming less focused on traditional carat milestones and more interested in achieving the look they want. The accessibility of lab-grown diamonds has helped make larger diamonds a realistic option for more people.
Why is sourcing exceptional diamonds direct from source so important?
Kim
Direct sourcing allows us to hand-select diamonds for each client and ring design. In some cases, we even have diamonds cut to our own specifications, including proprietary shapes such as the Tycoon 8 and Moval. This gives us greater control over quality, proportions and appearance.
Mike
We look beyond the grades on a certificate, focusing on proportions, facet patterns and ratios that influence a diamond's beauty and performance. Selecting every diamond ourselves means we can ensure it's the right fit for each client's ring.
What advice would you give someone wanting to create a timeless ring?
Start with the person who will wear it. The strongest designs aren't driven by trends but by personal style. Our advice is to resist overcomplicating the design, a thoughtful, well-proportioned ring with subtle personal details will stand the test of time and can eventually be passed down to future generations.
Why is designing, setting and manufacturing every custom piece in Australia important to Parker Diamonds?
Every Parker Diamonds engagement ring is custom designed, set and crafted in Melbourne. Keeping the process local allows us to maintain oversight from diamond selection through to the finished piece, ensuring a high level of quality and attention to detail.
It also means we can provide ongoing support through our Melbourne workshop, from resizing and cleaning to reconditioning and stone checks.
Parker Diamonds is celebrating its 15th anniversary. What are you most proud of?
Kim
I'm most proud of how much Parker Diamonds has grown while staying true to the values Mike and I started with. We began as a husband-and-wife team and now have an incredible group of people who share our passion for exceptional jewellery.
I'm especially proud knowing our rings have been part of so many significant moments around the world, from the Swiss Alps and Central Park to Paris. I'm also grateful that the Block Arcade has been our home for 15 years and that, after all these years, Mike and I are still smiling, laughing and enjoying the journey together.
Mike
When Kim and I started Parker Diamonds, it was a small husband-and-wife business built around our shared passion for exceptional engagement rings. Seeing it grow into a leading custom engagement ring destination has been an incredible achievement.
I'm most proud of the team we've built and the reputation we've earned through the quality of our work. Every piece still reflects the principles we started with: integrity, craftsmanship and a commitment to doing things properly. Knowing our rings have become part of such important moments in our clients' lives continues to motivate us.
Looking ahead, what's next for Parker Diamonds?
Kim
We're excited to continue evolving the Parker Diamonds experience, with a focus on expanding our digital presence and creating a more personalised online experience. We want clients to be able to connect with our expertise wherever they are, while maintaining the level of care they'd expect from our boutique. We'd also love to see Parker Diamonds pieces worn by more people around the world, including some familiar faces.
Mike
Our goal is to become Australia's leading engagement ring specialist while continuing to grow our bespoke offering. We're looking at expanding our presence throughout Victoria, growing our team and bringing the Parker Diamonds experience to more clients. Whatever the next chapter looks like, the focus will remain the same: delivering a truly personalised experience from diamond selection through to the finished ring.
