Questions
Will it tarnish or turn my skin green?
Our pieces are made for everyday wear, including the shower and the gym. They're tarnish-resistant and won't rust or leave a green mark. For gold and coloured finishes, keep them away from chlorine and harsh chemicals so the colour lasts longer. The exact material is listed in each product's details.
How long does delivery take?
Orders usually arrive in 8–15 working days with tracking. You'll get the tracking link by email once your order is dispatched. Delivery is free on orders over £35.
What if it doesn't fit or I change my mind?
You have 14 days from delivery to tell us, then 14 more days to send it back unworn for a refund. Ring sizes are listed in US sizing with a UK conversion in each ring's description.
Is it a good gift?
Yes. Most pieces are unisex, and every order includes a 14-day return window. Order early for birthdays and holidays, as delivery takes 8–15 working days.
