I am LOVING this ring. I found it whilst perusing nonesuch things (a regular indulgence of mine). It comes 'flat packed' and you just have to pop out the pieces and follow instructions to fit it together. Great idea with gorgeous results. It comes in three sizes and will cost you a mere £15.00 - what's not to love?
Take a look at nonesuch things its full of interesting, gorgeous bits and pieces. I'm addicted.
