There are plenty of stone dealers and jewellers who can provide separate stones and semi mount rings.However, it is not always easy to navigate buying loose stones and component parts, and you will still need an expert setter to set your stone. Additionally, if you have any issues with your ring it may be harder to pinpoint where responsibility lies if a number of different craftspeople have been involved in your ring.We recommend choosing one jeweller for your engagement ring. Most will be open to using your own stone, whether it’s one you bought, were gifted, or inherited.
