Diamonds: 3 C’s For more advice on diamonds and the different cuts, clarity and colours please visit our engagement ring buyer’s guide; this includes helpful tips such as how to secretly find out her finger size and we have also put together information on style, metal and diamonds to help you make an informed decision. Certificate Any loose diamond can be certified, but it's not cost-effective for smaller diamonds, where the cost of the certification can be more than the cost of the diamonds themselves! We certify all diamonds in single stone engagement rings (or the centre stone of trilogy engagement rings) over 0.25ct, at no extra charge to you. Of course, we'd be happy to certify smaller diamonds by arrangement; however we may have to charge for this. Our diamond certificates are from independent gemmological institutes such as IGI, EGL and GIA. Sample service If you are not 100% sure about which ring or even diamond size/cut to choose, you can make use of our sample service and borrow one of our replica rings to use for the proposal before choosing the right ring together. We have replicas of most of the engagement rings on our website, both for the sample service and to show you if you live near Brighton and want to make an appointment to come and see us. Finding a wedding ring to match One more thing you should consider when choosing her engagement ring is the kind of wedding ring she will later be wearing with it. We have many designs of shaped wedding rings to fit next to all kinds of solitaire engagement ring.
