How To Measure
1) The Hands-on Method
- Grab a tape measure, length of string or strip of paper.
- Wrap it around the finger you'll wear your ring on—if you’re creating a ring stack, consider where on your finger the ring will sit—and mark the place where it joins.
- Lay your string or paper strip on a flat surface and use a ruler to measure the length up to the mark. Use the chart above to match the measurement to the closest ring size.
2) Measure an Existing Ring
- Choose a ring that already fits your finger well.
- Measure the interior diameter of the ring in millimeters (mm).
- Use the measurement chart above to match the size of your ring to the closest size in mm.

We offer free shipping on all orders, with discreet packaging to ensure your privacy. You can also choose to pick up your jewellery from our Sydney showroom or Melbourne store. Returns are accepted on all non-customised jewellery. For more details, please read our returns policy.
Our diamonds, both lab-grown and natural, are sourced from suppliers who adhere to strict ethical standards. We are committed to offering only the highest quality diamonds, carefully selecting colours from D to G and clarity from VVS2 to VS1 only.
We use high-grade gold and platinum supplied by Australia’s leading specialists in precious metals and jewellery production. Our metals are alloyed in-house, ensuring the highest quality. All our white gold is rhodium plated for enhanced durability and shine.
Product Care
To ensure your jewellery remains as beautiful as the day you received it, proper care and regular maintenance are essential. This guide offers tailored advice for each material
Gold Care
Solid gold is durable but can scratch over time. Keep it away from chemicals, lotions, cleaning products, and chlorine, which can cause oxidation and brittleness. Always remove jewellery before swimming, exercising, or manual tasks, including household chores. Store pieces in a soft-lined box, separated from other jewellery, especially diamonds. The rhodium plating on white gold wears away over time; minimise polishing to slow this process. Check regularly for damage and service annually, including rhodium plating when the warmer metal begins to show.
Platinum
Platinum is a dense, durable metal but can develop a natural patina over time. Keep platinum away from chemicals, lotions, cleaning products, and chlorine, which can cause oxidation and scratching. Always remove platinum jewellery before exercising, or doing manual tasks, including household chores. While resilient, platinum can scratch more easily than gold, so store it separately to avoid abrasion, including from diamonds.
Diamonds
Diamonds are the hardest natural material, but are not indestructible. They can still chip or break if struck with force, particularly on edges or points. Protect your diamonds from knocks by being mindful of how you wear your rings or other pieces. Store jewellery individually in its original packaging to avoid contact and scratching with other diamonds.
Gemstones & Pearls
Gemstones, including sapphires, are durable but still require care. Pearls especially are delicate and require particularly special care. Avoid exposure to harsh chemicals, lotions, and cleaning products. Remove pearl and gemstone jewellery before swimming, exercising, or doing household chores to prevent scratches. Clean only with a soft cloth, or gentle soap and water. Most gemstones and all pearls are unsuitable for an ultrasonic cleaner.
Chains
Store in a soft-lined box, separated from other jewellery to minimise tangling and avoid bends, dents, or kinks. Clean with a soft cloth and regularly check for damage. Note that white gold chains may require regular rhodium plating.
This piece was designed with our signature 1.2mm band. It is specifically designed and crafted to be not only delicate-looking, but also long-lasting. However, we know some people prefer a thicker band, and we can customize our bands to 1.5mm or 2mm for most designs. Please reach out to our customer care team with any questions about customizing the band for this piece!
We can create our engagement designs with various diamond cuts. If you love this design but are hoping for a different shape for your focal stone, please reach out for more information!
