21 Oct HOW TO CHOOSE AND BUY DIAMONDS
The quality of a diamond is determined by 4 things:
– Carat Weight
CARAT WEIGHT: A diamond’s weight is measured in carats. The unit smaller than a carat is a point. There are 100 points to a carat. Small stones are usually referred to as weighing 10 points, 12 points etc. Even 1 point diamonds are used in jewellery. As the size of a stone increases so too does the value because the larger stones are rarer. Therefore, a two-carat diamond is worth double a one-carat stone of the same quality.
CLARITY: A diamond can be sold as perfect or flawless if it shows no flaws to a trained eye when magnified ten times. Other diamonds are valued according to the number, kind and location of the inclusions. In many cases, the inclusions do not effect the beauty of the stone as seen by the naked eye, but they affect the price.
CUT: Whatever the clarity and colour of a diamond, only expert cutting can reveal its full beauty. It has to be perfectly proportioned to a minute accuracy. Each tiny facet must be symmetrical, polished into the world’s hardest substance at an angle that may not vary by more than half a degree. Diamond cutters are amongst the most skilled and best paid craftsmen. It is their work which turns a whitish pebble into a brilliant gem. The quality of the cutting has much to do with the final value.
COLOUR: Diamonds come in many colours. White, pale yellow, coffee brown, pink, red, blue, green and black. The Hope diamond, one of the most famous, is blue like a sapphire.
The most popular engagement rings are clear, sparkling white. However, there are many shades of white. All can be stunning in a well-cut diamond. Because the purest white is the rarest, it commands a higher price.
Commercially the term blue-white is often used to describe diamonds that are actually white. However, this usage is not accurate. Diamonds with any tinge of blue are very rare.
The finest diamonds regularly sold in engagement rings have the clarity of a drop of pure water, are colourless except for the rainbow fire produced by the diamond’s power to break up light and give back a flash of hue in the spectrum. Diamonds reflect colour around them.
To judge the colour of the diamond itself, you need to look at it on white paper in north light on a clear day
Tip: To get the most for your money, buy the diamond from a reputable dealer in the UK (Hatton Garden, London) and then get it set into a ring or whatever. Be careful who you give it to to do this. Do your research. I have also bought diamonds from Pawn shops and then had the design reset to create earrings or whatever…..occasionally good value. Also look at buying in local auctions as once again you can buy brooches (less fashionable these days) and put the stones in a ring or whatever. Happy expensive shopping…….!
