We are fully aware of the importance of choosing the right style for your jewellery, but we also take into consideration that you may need help in choosing the right size.
When buying a ring, consider its thickness, as you may need a bigger size if the ring has a deeper band width. Also, the best time to get your ring size is the evening, and pay attention to how you feel, as fingers are at least half a size smaller when you are cold.
Here you have a list of sizes and their diameters (in mm).

The perfect replacement for the original jump ring on one of the charms on my old-fashioned charm bracelet. The jump ring was damaged and lost when I caught it whilst removing a sweater but thank goodness the charm was fine. This item was the perfect fit and easy to open, put my charm back onto my bracelet and close again.
Very good quality, nice and thick silver. Very impressed!
Good price and very prompt delivery (despite the postal strike...)
Thankyou!
