Ring Size Chart

Not sure of your ring size? Read our concise chart for measuring women’s ring sizes below. 

Our top tips 

For the most accurate result make sure that you take finger measurements in the evening when the hands are warm, as this is when finger diameter is largest. In colder weather, fingers are slimmer – sometimes up to half a size! You want to make sure that your ring will fit whether the wearer is warm or cool and that it’s never too tight.

While our ring size chart offers a good reference, we recommend you get your ring sized professionally in one of our boutiques. If you can’t visit, simply follow our ring size chart.

Like it

It is a very pretty necklace and I like it but do not wear overnight as it will tagle very badly. You have to keep arranging it though , so it stays where should stay , nicely like on the pic

Elegant and sophisticated

Love the necklace, especially the ability to change the length to suit different events and outfits. Elegant design that can be worn for special events or general day wear. Very happy with my purchase and will look to order more items

Gorgeous necklace

Worth investing in a jewellery stand as it can tangle quite easily but lovely item and length is fully adjustable.
