Ring Sizing Stick or sizer mandrel for checking the size of rings you purchase and for checking clients’ own ring sizes. You can view our own range of ring settings here! Just give clients the option to order a ring sizer along with their Sending Kit and be sure their ring will fit nicely. We usually send these free of charge and ask clients to return them along with their elements such as breastmilk or cremation ashes.

A UK Ring Sizing Mandrel is made from zinc alloy and is lightweight. They cover a wide range of sizes (see below) so they’re ideal for clients with most finger sizes. Don’t forget, our handmade rings here at Keepsaker Supplies can be made in literally any size, including half and quarter UK and US sizes, if you can’t see the size you want just choose the closest and put what you need in the comments on the checkout!

Using a Ring Sizing Stick or UK Ring Sizing Mandrel

Jewellery tool to measure a ring’s size.

Adjusting a Client’s Ring Size

If your client orders a comfort fit band like our twisted band ring then choose the ring in the size they provide. If they choose a chunky band ring (3mm or wider in a flat shank) then we recommend making the ring a UK size above to make up for the extra area of skin compressed by the shank. For example, if they measure a size P then make a P twist or a Q chunky ring. For US ring sizes, go up a half size. Clients may not understand this but all you can do is your best to make a recommendation; clients may still want the size P but just let them know they can get the ring enlarged at a local jewellers if necessary but that they’re responsible for paying for that. Please see our ring sizer instructions for how we word this best.

If they’re not sure, it’s best to go for the size ring that’s a little tight. It’s easy to enlarge a ring one size (sometimes free) but very very difficult to reduce the size. Clients can add a ring reducer but they’re not too comfortable.


Sterilise them in between clients with  biodegradable plant fibre wipes then pop them under the UV lamp to dry.

If working with UV resin we recommend you work in layers to achieve beautiful depths of colour.
