Ring Sizing Chart
Why Is It Important?
Knowing the finger size before the design process begins is crucial so that accurate pricing can be quoted. Metal is quoted per gram, so having a clear idea of how much metal will be within the design helps us provide an accurate quote to each client.
Another reason why it is key to know the finger size before the design process begins, is sometimes designs can be restricted by how small or large the finger size is. Knowing as much information before initiating the design helps the process of creating your dream ring run smoothly.
In the common event that it will be difficult to retrieve the finger size for your partner, we can create the desired ring in an average finger size or pass on ideas on how to retrieve a close estimate of your partners finger size, being aware of the likelihood that the ring may need to go into one of our workshops for resizing.
