When you sell diamond jewellery or are buying diamond engagement rings, you should ask for a diamond certificate. The cert will contain all the details about the jewelry and the diamond – it will list the size of the stone, it’s color and clarity and list any flaws the gem may have. A jewelry valuation will also state what metal the item is made from – if the jewellry engagement ring is in platinum – it will say so, and give the weight of the metal. All bridal rings, eternity rings, engagement rings and wedding rings should be certified and valued.
Diamond rings, engagement and eternity rings, whether they have diamonds or semi precious stones should be certified by a gemologist or a jeweler. Jewellery stores who make up your ring design should offer one for free – if not ask them – if you go to another jeweller or jewelry shop afterwards it will cost you up to 5% of the value of the ring – and you will also need a diamond certificate and a valuation for insurance purposes.
Your certificate should have the following
Carat Weight (o.45ct)
Clarity (FlawlessVVS1)
Colour (G)
Cut (pear shape)
Cost (in US$ or your local currency)
The valuation should look like:
1 x 18ct yellow gold claw type engagement ring (4.2g) set with with 1 x 0.45ct pear shaped diamond, color G, clarity VVS1. – US$ 2400
The diamond certificate and the valuation are two separate documents – the valuation will need updating once a year at least – and it is also a good idea to gave the setting checked by a manufacturing jeweller. They will look at the claws and the setting and make sure that the stone is still firmly in place. They will, if you are lucky, also give your ring a quick polish and a clean – you will be amazed how good it will look afterwards.

Your ring design will determine how often you should have it checked – a stone in a tube will be safer than a claw setting – if you are active and wear your jewellry engagement ring all the time you should have it checked more often. You should also have it checked before you sell diamond jewellery, and ask a jeweler to check it if you are buying diamond engagement rings second hand. Bridal rings and ring sets are often difficult to re size – so if you have inherited a ring, or it has been passed down from mom or gran – rather take it directly to a manufacturing jeweler – they will advise whether it is in a safe state to wear – old rings are often worn out at the bottom and the claws are thin – not very sage. Old rings are often not suitable to be worn – or repaired – no matter how much you wish to wear it – follow the advice of an expert rather than take a chance of losing the diamond. Wedding bands are easier to gauge – and there is no stone to lose. Jewellery stores will advise on rings engagement, but a manufacturing goldsmith is often a better option.
