Sizing Information
Most vintage jewellery buyers purchase rings without being limited by the listed size and have them professionally resized by their local jeweller to ensure a perfect fit. This means you can shop freely regardless of the ring size provided.
We are currently working on offering a re-sizing service for those who wish to add it at checkout.
Rings
You can measure your finger using a measuring tape. Wrap it around the base of your finger, mark the length and then use the chart below to determine your size.

Bracelets
To find your bracelet size, use a tape measure to measure the circumference of your wrist. Compare this to the listed bracelet length for your ideal fit.
Necklaces
For necklaces, measure the circumference of your neck and compare it to the necklace length to help you visualise where it will sit.
