Ring Size

Unsure of your ring size? Our complimentary ring sizer can help take the guess work out of determining your ring size. Allowing you to determine your best ring size, the sizes on our ring size correlate to our standard ring sizes. 

Our complimentary ring sizers can be added to your cart for check out.


Our rings are made to standard US/Canadian ring sizing. We make our womens rings in sizes 5, 6, 7, 8, 9 and 10 as standard and our mens rings in 9, 10, 11, 12 and 13 as standard in most sizes. Half sizes are not made as part of our range.

Your ring size is determined by measuring the inside diameter of your ring at the widest section from the inside of the band in millimetres or using our complimentary ring sizer.

If you are unsure of your ring size please check our ring size conversion charts below or email our customer service team at to check your ring size with us.

We are constantly restocking sizes so if your size is not available please reach out and we can let you know when your size will be in. We also offer custom sizes for an additional custom fee. 





Our necklaces are designed in a range of lengths to partner together and layer during wear. We believe that there is never such a thing as too many and encourage our customers to get creative and layer their ToniMay collections 

Our necklaces typically come in 4 lengths from choker (36cm) through to a longer opera style chains (64cm). Our chains lengths are 36cm, 40cm, 46cm, 50cm and 64cm. 

If you are looking to layer your ToniMay necklaces, particularly if you have styles where chain lengths are the same we recommend getting your hands on one of our chain extenders which will allow you to mix and match your chain lengths for layering. Our chain extenders can be used with all lobster clasp chains however are not able to be used with our toggle clasp necklaces such as the Herkimer, Alchemy or Lost Pearl necklaces. 



Our cuffs are made to standard sizing between 14 - 16cm in length.

Our cuffs are not designed to be tightened or stretched to fit your wrist. Please avoid stretching open cuffs to take them on and off or tightening cuffs on the wrist to fit snug. Cuffs should be slid on and off the wrist from the thinnest part of the side of the wrist. Stretching cuffs open and closed can cause a weakness in the band and cause cuffs to crack. This can also weaken the stone settings.

Unfortunately we are unable to offer custom size cuffs.
