What to consider about fit
Finger size can vary during the day. Measure on more than one occasion. A wider ring can feel tighter; ask us about the fit of the design you choose.
Resizing after purchase
We offer one complimentary resizing of our diamond rings within 12 months of receiving your order. Not all rings can be resized. Read the complimentary resizing terms and contact us about the ring you are considering.
Choosing a ring as a surprise?
Contact us if you do not know the ring size. For questions about ring designs or diamonds, you can book a complimentary consultation.
