Diamond & Materials

Our lab-grown diamonds 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

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 is thoughtfully designed and crafted to balance beauty, comfort, and lasting durability. We can customize designs to suit your preferences. Please reach out to our customer care team with any questions about customizing the band for this piece!
