That's something I've never thought about, looking at what the people around her are wearing. That may really be helpful in determining what size to get for her. Thanks for that.Bron357|1479597978|4100659 said:Hmmm, it depends. As a guide, what size diamonds are your girlfriends friends, family and associates wearing? In some circles .50 carat is the norm, in others it might be 2 carats plus. When I was first engaged in my early 20s I thought 1 carat was mammoth. Many decades later I'm wearing much bigger. Also hand size has a bearing, 1 carat on a petite hand with size 4 fingers covers a lot more finger than the same stone on a large hand with size 9 fingers. Whatever you decide on, get the best quality for money. Most import in my opinion are cut first, clarity second and colour third. A poorly cut diamond just doesn't sparkle properly and that the main thing a diamond is expected to do. Clarity down to S 1 can be eye clean and colour down to H seems nicely white to most people. when it comes down to choosing the best diamond for your money, post again here and ask the experienced PSers for their guidance. Congratulations.
