How do I ensure I order the correct size?

We recommend downloading "Ring Sizer - Ring Fing" from the Apple or Google store. Place a ring your partner already wears (on their ring finger) into the circle and adjust until it fits perfectly. Modern and sneaky!

For our clients making a bespoke ring for themselves, we'll post a complimentary ring sizer once the design is agreed.

What if the ring doesn’t fit?

Most rings can be easily resized and we offer one complimentary resize after delivery.

Contact us at hello@miyazatodiamonds.com to arrange.

Important: Miyazato Diamonds isn't responsible for items damaged or lost in return post. Please package securely, use the correct address, and choose insured/signed-for delivery.

All our jewellery comes with a lifetime guarantee against manufacturing faults or defects. This does not cover accidents, impacts, fair wear and tear, or damage from mishandling and lack of care.

We believe that we offer a gold standard guarantee and after-care service. To read about this in full, please visit our full Warranty & Guarantees page here.

We also offer a complimentary deep clean and polish once a year. We highly encourage our clients to take advantage of this as it gives us the opportunity to check the claws and setting for any inevitable daily knocks and bumps which might have weakened them overtime.

No – and we're proud of that.

Our approach delivers all the bespoke, luxurious elements of high jewellery without traditional store overheads. Without rent or expensive display stock, we source the best, most competitively priced diamonds available right now – not whatever's sitting in a window.

Every ring and piece of fine jewellery we create is bespoke, made to order, and will only ever be worn by one person: you.
