The circumference of the bangle is approx. 22 cm / 8.5" and 5 mm thickness. 

70 mm by 60 mm diameter.  

It comes in a pretty gift bag.

It is made of 925 sterling silver and stamped with a 925 silver mark.

This bangle is hollow. I have the same bangle also in solid silver which is a 3.5 mm thick bangle for £49.99 and 5 mm thick bangle for £79.99. You can find them in my ebay shop. 

Do not be fooled by cheap silver plated bangles.
