We work with a range of materials depending on the design of the jewellery.

For waterproof designs we use stainless steel with PVD 18k gold. However, we have found that for more intricate designs, softer metals are needed for a more elegant finish. With this in mind, we use solid sterling silver or high-quality brass generously coated with rhodium or 18k gold. To know what material each piece is made of, please read the specification below each product.

All our jewelry is nickel-free and hypoallergenic.

To help protect the durability and high-quality of your jewellery, remove your jewellery when you shower, bathe or engage in heavy exercise, particularly when swimming in the sea or a chlorinated swimming pool. Avoid spraying perfume, applying creams or any other liquids directly onto your jewellery.

We advise that you keep your jewellery clean by using a soft cloth when needed.

If there is an item that you would like to purchase but is currently out of stock, please click the ‘notify me’ button and enter your email address. You will be notified by email when the product comes back in stock.

To find the perfect fit we recommend measuring either the circumference of your finger or the diameter of a ring you already have. You can find our full Ring Sizing Guide Here.
