Hi there, I'm posting from the UK and was lucky enough to receive a set of studs for Christmas a couple of years ago. With my birthday in a couple of months hubby has suggested getting these upgraded. We have a small budget of £1.000 and the stones will need to be from BlueNile. He previously chose IF stones but I don't think this is necessary..? Looking for something super sparkly and larger than my 0.23 per stud. Thanks all in advance x
