COMPLIMENTARY RING SIZING

Don’t panic if your ring choice too large or too small! Your first sizing is complimentary to ensure the perfect fit.

If we can’t size your ring, we’ll exchange it for the same ring in the correct size or specially make a ring for you in the correct size. If we need to specially make a ring for you, this could take a few weeks.

You can take the ring to your nearest ROX boutique where we’ll check your partner’s finger size and re-size it at our workshop. A simple ring sizing (i.e. up and down a couple of sizes) normally takes just a few days but we do offer a same day service in Glasgow if you are in a hurry. More complex sizings, can take longer and we will advise at the time of your visit.

Alternatively, we can collect your ring via secure courier, re-size it at our workshop and then ship it back to you. You can check the size your finger using the complimentary finger sizer sent with your order. Please request a Returns Merchandise Authorisation (RMA) so we can organise collection on a day to suit you.

All ROX jewellery comes with a warranty that covers manufacturing defects for a period of one year from the date of original purchase from an authorised ROX dealer. This warranty does not cover damage from normal wear and tear, abuse, accidents, or intentional damage.

You can extend the warranty for your ROX jewellery to three years if you register your ROX jewellery via the ROX website by clicking this link: https://www.rox.co.uk/register

Registering for the ROX warranty extension is quick and simple. Please make sure you have the Certificate of Origin of your ROX jewellery at hand before you start the registration process. You will need the Purchase Date and SKU to register your jewellery.

The warranty extension will cover any manufacturing defects that are acknowledged as such by ROX. The warranty extension does not cover damage from normal wear and tear, abuse, accidents, or intentional damage.

Your jewellery will require care and regular maintenance to to protect its appearance.

We recommend that you visit ROX at least once a year to have your jewellery professionally cleaned and checked. This annual check helps identify potential issues like loose settings or damaged clasps, preventing loss of stones or other damage. Some insurance companies make this a requirement of their insurance policy. More frequent inspections, perhaps twice or even three times a year, may be advisable for items worn daily.

Here’s our ROX top tips for caring for your jewellery:

Don’t wear your jewellery while doing heavy lifting, DIY, gardening or working out in the gym. Even though a diamond is durable, it can be chipped by a hard blow.

Avoid contact with gritty substances. Gritty substances can scratch and mark gold and platinum and coloured stones.

Don’t let your jewellery come in contact with chlorine bleach or harsh chemicals when you are doing household chores. Chlorine can lead to discoloration, tarnishing, and even structural weakening of some metals, potentially causing stones to loosen or fall out.

Remove your jewellery when applying everyday lotions such as sunscreen and perfume. Lotions create a film on your jewellery and can even penetrate some porous coloured gemstones.

Store your jewellery carefully. Store each item of jewellery separately in pouches to avoid them scratching each other. Keep chains fastened and lay them flat so they don’t get tangled up.
