Care & cleaning
Your pieces are made to be worn. A little care is all they ask in return.

The simplest rule is also the most effective — put your jewellery on last and take it off first. Perfume, moisturiser and hairspray should always be fully dry before your pieces go on, and jewellery should come off before you wash your hands, shower or exercise. Keep your pieces away from household chemicals, sunscreen and anything abrasive, and if they do get wet, dry them gently and thoroughly straight away. These small habits, kept consistently, are what keep fine jewellery looking the way it should for years.

To clean your pieces at home, all you need is a small bowl of warm water with a drop of mild dish soap. Let your piece sit in the solution for a few minutes, then use a very soft cloth or a soft-bristled toothbrush to gently work around any settings or chain links. Rinse thoroughly under lukewarm running water to remove any soap residue, then pat dry immediately with a clean, lint-free cloth and allow to air dry completely before wearing or storing. A light clean every few weeks is all it takes to keep your jewellery looking its brightest — and far easier than trying to undo heavy buildup later.

18k gold vermeil

Gold vermeil is sterling silver coated in a layer of 18k solid gold, giving it a warm, luminous finish that wears beautifully. It appreciates being kept away from water, perfume and harsh products, and with a little care it will hold its colour and warmth for a long time.


14k gold filled

Gold filled is made by bonding a layer of solid 14k gold to a base metal core, giving it a rich, lasting finish that holds up well to everyday wear. Keep it away from chemicals and moisture and it will stay looking its best for years to come.


925 sterling silver

Sterling silver is 92.5% pure silver, known for its cool, luminous finish. It does tarnish naturally over time as the metal reacts with air and moisture — this is entirely normal and nothing to worry about. A gentle clean will always restore it, and wearing your silver regularly actually helps keep it bright.


Cubic zirconia

Cubic zirconia is a beautifully brilliant stone designed for everyday wear. A regular gentle clean is all it needs to keep its sparkle looking its best.


Moissanite

Moissanite is a lab created gemstone known for its exceptional brilliance and durability. Its sparkle is permanent — it will not cloud or fade over time. A gentle clean every now and then is all it needs to keep it looking its best.

There are moments when the kindest thing you can do for your jewellery is simply take it off. Before a shower or bath, before swimming in the ocean or a pool, before exercising or anything physical, before bed — these are the times when exposure to water, sweat, salt or friction does the most quiet damage over time. The same goes for applying beauty products, cooking with acidic ingredients, or doing any household cleaning. Removing your pieces in these moments takes only a second, and it is one of the most meaningful ways to protect them for the long term.
