It's really unusual but I have been wanting an armour ring like this for a while. The first one I saw was in Topshop in Westfield, but they only had medium and large sizes left.
Then this one came out recently and my flatmate showed me the link and it is now mine! It sold out within a few days online (I checked every now and then).
The detailing is beautiful, although it's not everyone's style.. I adore it.
