Ring sizes
If you want to wear a single ring on your finger, use a ring that is similar to the one that you are buying to work out ths size; your ring size can vary between a wide and a narrow ring shank.

If you want to wear ring upon ring (multiple rings on one finger), the rings should be one size bigger than your regular size. We're keeping our eye on the Pandora Fairytale Sparkle Ring (￡50, House of Fraser).

Creating your own necklace
Pandora also let you create your own necklace. If you want to buy one as a gift over the Black Friday weekend, here's everything you need to know.

First, choose the favourite chain: these are available in varying lengths and different shades of sterling silver, spanning from heavily oxidised to glistening. Then, combine it with one of their pendants.

As well as creating a bespoke necklace of your own, Pandora Black Friday also have a range of ready-designed necklaces. We love the simplicity of the Loving Hearts of Pandora necklace, which is currently available at John Greed for ￡80.

'Moments' silver charm bracelet buying guide
Pandora is most-well known for its charm bracelets. Here's what you should keep in mind:

The most popular bracelet size is 19 cm.
A bracelet is perfectly sized when you measure your wrist tightly and add 2 cm.
If you are between sizes ask yourself how you like to wear your bracelet. If you wear it tightly choose the smaller size and if you like to wear it loosely take the next size up.
At first the new bracelet will feel stiff, which can make it seem uncomfortably tight. However the bracelet will quickly soften and become more flexible as you wear it.
If you wear your bracelet often then it will grow about 1 cm over the first year. This time frame will depend on how often you wear it and how many charms you have on your bracelet. · After one year the bracelet might still grow slightly but not much.
If you start off with just a few charms your bracelet might seem loose in the beginning. This will change as you add more charms.
You can also measure a bracelet you already have. You should measure end to end for the correct size.
