Description

Would you go out and buy a car without an MOT certificate?

Without knowing it is roadworthy in the long run and not only on the test drive? Without knowing the car that you are buying meets road safety standards and is worth the thousands of pounds you are paying for it? And you would also make sure that the MOT certificate is from a recognized garage which is approved to issue these certificates, yes?

In the olden days, your local jeweller would provide some sort of verbal assurance that “oh, the diamond you are buying from us is very good quality, do not worry, you are getting an excellent deal” or hand over a store piece of paper mentioning the quality. This is where the jeweler made enormous profits to your detriment.

You had to trust them and their personal knowledge for quality assurance. It goes without saying that diamond certificates from the GIA, IGI or other trade recognized labs are an important document to demand while purchasing diamond jewellery, but…
what is a certificate and why are they important? Well, talking about certified diamonds, they are graded for quality by scientific laboratories across the world. These are generally the larger central thing in your engagement ring which has the most value in the ring you are buying (on average around 80-90% of the total value).

The most important lab, being the GIA, trains and prepares their graders to be qualified to check the colour, clarity, cut and carat weight of the diamond and the laboratories they work in are fully equipped to check the authenticity. For grading the colour, a gemologist checks it against master colour samples and for determining the clarity, they inspect the diamond for black knots, cracks, chipped elements, etc.

How do they look inside them? Well, they do so with the help of the microscope. All in all, if you are buying any diamond jewellery or one of the most special jewellery of your life… engagement ring, go only for certified diamond engagement rings. Why certified diamond engagement ring, you ask?
Well, the first and foremost reason being the value of the diamond. Diamonds are expensive and when you are shelling out large amounts on something as special as your engagement ring, you should be sure of its authenticity and what is better assurance than a diamond with GIA or IGI certification. Besides this, if you want your jewellery to be insured, you will have to provide the insurance company with some kind of documentation for the jewellery's authenticity so that they analyse its retail replacement value.

Apart from diamond certification, there is also a diamond appraisal and people often tend to get confused between the two. While diamond appraisal is for insurance purpose and is prepared by the seller keeping in mind the estimated value of the diamond, a diamond certificate is an analysis of diamond's quality and is prepared after the gemologist checks the stone for all the parameters.

The diamond in certified diamond engagement ring, is graded on the basis of 4Cs (cut, colour, clarity, carat weight): Colour – A colourless diamond is considered to be of the highest quality, colours ranging from D -Z and then fancy colours. Clarity – Diamond without microscopic imperfections (inclusions or blemishes), Flawless being the highest clarity down to I3. Cut – Is said to be very important.

The better the cut, the more attention diamond would grab as it would sparkle more. Carat weight – It's about the total weight of the diamond and not about its measurements. Choose a larger diamond that comes within your budget but in doing so, don't sacrifice on the quality. So, now that you are aware of the importance of certified diamonds and have read about 4Cs, buy only certified diamond engagement ring.

These rings are great value for your money. The key is to visit a reputable jeweler and still demand the Gia công sơn or IGI diamond grading document so that the quality can be verified by any other person in the trade.
