Frequently Asked Questions

Can I book an appointment to view your rings in person?

Yes, private appointments are available at our Sydney studio. You can explore our ready-to-wear collection, discuss custom options, or try on pieces in a relaxed and personal setting. Appointments can be booked online via our website.

Do your diamond rings come with certification?

Yes, our diamonds are certified by independent labs, like GIA or IGI, and ethically sourced. Each diamond is selected for its cut, clarity, colour and carat weight, ensuring your ring has exceptional sparkle and integrity.

What metals are available for your rings?

We offer our rings in 9k, 10k, 14k, and 18k rose, yellow or white gold, as well as platinum. Each metal is selected for its durability, tone, and ability to complement your chosen gemstone.

How long does it take to make a ring to order?

If you're ordering a bespoke or customised ring, the typical production time is 5 to 7 weeks. This allows us to source your gemstone if necessary, refine your design, and craft your piece with the care and precision it deserves.

Do you offer resizing for your rings?

Yes, we offer ring resizing for our rings. We recommend confirming your correct ring size before ordering, but if you’re unsure, we’re happy to assist — either remotely or in-studio. We offer one complimentary resize within 2 months of purchase.

Does metal colour change the way a diamond looks?

As diamonds are largely colourless and translucent, metal that holds it does lend its colour to the diamond, influencing how warm-toned or colourless it appears. Platinum and white gold settings are a great choice for high colour diamonds, such as D to G colours, as they accentuate their whiteness (ore more accurately, their colourlessness). Yellow and rose gold create a warm contrast, making yellowish diamonds, such as H to M colours, appear whiter.

Should I choose a lab-grown or natural diamond?

The choice between a lab-grown and a natural diamond comes down to your values, priorities, and what the piece of jewellery represents to you.

Lab-grown diamonds offer the same sparkle, structure and hardness as natural diamonds — they’re chemically and optically identical, but created in a laboratory using advanced technology. Their lower price point means you can often select a larger or higher quality diamond for your budget.

Natural diamonds, on the other hand, hold a unique allure. Formed over billions of years under intense heat and pressure deep within the Earth, each stone is a rare geological wonder — a one-of-a-kind treasure shaped by time. Natural diamonds also tend to hold their value better over time due to their rarity and enduring demand.

If budget, size and sustainability are top priorities, a lab-grown diamond may be right for you. If you’re drawn to rarity, long term value and the romance of deep time, a natural diamond offers something truly special. Both are beautiful — the best choice is the one that feels most meaningful to you.

How do the 4Cs affect the beauty and value of a diamond?

The 4Cs — Cut, Colour, Clarity and Carat — are the universal standards for evaluating the quality and value of a diamond. Each factor plays a unique role in determining a diamond’s overall beauty and rarity.

Cut is perhaps the most important of the four, as it directly affects how a diamond reflects light. A well-cut diamond will sparkle more brilliantly and appear more lively than one with a poor cut, even if other characteristics are equal.

Colour refers to the presence of a yellow or brown tint in white diamonds. The GIA colour grading scale ranges from D (colourless and most rare) to Z (light yellow). The closer a diamond is to colourless, the more valuable it tends to be.

Clarity assesses the presence of internal features (inclusions) or external marks (blemishes), which are natural byproducts of a diamond’s formation. While most inclusions are not visible to the naked eye, higher clarity grades indicate fewer and smaller imperfections.

Carat measures a diamond’s weight and often correlates with size. While larger diamonds are generally more valuable, carat should always be considered alongside the other three Cs for a truly beautiful and well-balanced stone.

We guide our clients through the 4Cs to help them select a diamond that offers both beauty and value.

How do I choose the right diamond size for my budget?

Consider balancing the 4Cs to maximise value while staying within budget. A well-designed ring can enhance the perception of your diamond’s colour, size and sparkle. We are happy to guide you through this process and help you select the best quality and value-for-money diamond.

What is the difference between natural and lab-grown diamonds?

Natural diamonds are formed over billions of years beneath the Earth’s surface, shaped by intense heat and pressure in a process that cannot be replicated by time. In contrast, lab-grown diamonds are created in advanced facilities using technology that mimics this natural process, offering a visually identical but more affordable alternative.

While lab-grown diamonds are often praised for their lower cost and accessibility — allowing couples to choose larger stones with higher clarity and colour grades — they typically do not retain value in the same way as natural diamonds. It's also worth noting that, despite common perception, lab-grown diamonds are not entirely without environmental impact, as their production requires substantial energy.

Each type of diamond has its advantages. Natural diamonds are prized for their rarity, enduring value, and timeless symbolism, while lab-grown diamonds can be an appealing choice for those prioritising size and budget. The right option ultimately comes down to your values, priorities and personal preference.
