There are so many engagement rings to choose from it’s a wonder anyone can ever choose (leaving a picture out with a big marker ring round your choice is often a good hint if you want him to get it spot on).

This emerald cut solitaire should thrill someone really lucky but the stone comes in a variety of cuts if you would rather something different. Find it at Cartier.
