Our Lewins Jewellery Size Guide, provides a complete comprehensive guide, to finding the perfect fit for your new jewellery piece, whether that be a ring, necklace, bracelet or even earrings.

There is about a 1mm difference between each whole letter ring size. Using our ‘Goldilocks Ring Rule’, we help you confidently find the happy medium, between a ring feeling a bit too tight or a bit too loose.

From the shape and composition of your finger to environment, activity and well being. We give you advice on how to measure your finger for rings with wide bands, rings for your little finger and if you are stacking your rings together. 

There are so many methods used to find your rings size, from: the string, the old ring, the printed tape-measure, the plastic adjustable multi-sizer to the jewellers method. We take a look at how accurate these methods are.

The evolution of diamond fashioning, from rough to cut stones have shifted throughout the decades. Showcasing a diverse range of shapes and cuts. From the revival of old cuts, to the reformed round brilliant and adventurous fancy cuts.
