    Diamond Buying Tips

    People mark special events with sentimental gifts of jewellery. While weddings reign as the biggest diamond event, there are many small yet glorious celebrations that are honoured with beautiful gemstones, such as new jobs, anniversaries, graduations, births…the list, happily, is endless.


    So how do people learn about diamonds so they can buy, own and enjoy them with confidence? Nonprofit GIA, the world’s foremost authority in gems and jewellery and the creator of the famous 4Cs of diamond quality offers these five tips:


    Choose a qualified jeweller. Select a jeweller as you would a doctor, a lawyer or any professional. Ask around. Find someone who is a trained gemmologist, a GIA Graduate Gemologist or GIA Accredited Jewelry Professional, and is affiliated with a professional jewellery association.


    Do your research. GIA’s Web site offers in-depth information on diamonds, pearls and other gemstones. Knowing the 4Cs helps you speak the language of diamonds and communicate with jewellers.


    Learn the 4Cs. All diamonds are rare and no two diamonds are alike. A diamond’s quality and rarity is determined by its unique combination of characteristics of Colour, Cut, Clarity and Carat Weight. The GIA International Diamond Grading SystemTM, used around the world to describe diamond quality was developed by GIA in the 1950s and is based on the 4Cs.


    Colour: Colourless diamonds are extremely uncommon. Most diamonds have a slight yellow or brown tint. GIA uses letters to represent colours, beginning with D (colourless) and ending at Z (light yellow or brown). “Fancy coloured diamonds” come in every colour imaginable, are also very unusual. GIA has a separate grading colour grading system just for these rare gems.
    Clarity: Nearly all diamonds contain unique clarity characteristics. Flawless diamonds are exceptional and costly. Most inclusions are invisible unless magnified.

    Cut: While diamonds come in different shapes, such as round, pear or marquise, the term “cut” refers to a diamond’s complex relationship with light – how light strikes the surface, how much enters the diamond and how, in what form light returns to your eye. Diamonds with fine proportions, symmetry, and polish optimize their interaction with light, and have increased brightness, fire, and scintillation.

    Carat: Diamonds are weighed in metric carats. Two carats weight about the same as a small paper clip. A carat is divided into 100 “points”, so a diamond of 50 points weighs 0.50 carats.


    Get an independent diamond grading report. A diamond grading report tells you the exact gemmological quality of your diamond. Is it a natural diamond? Is it a laboratory-grown diamond? Has it been treated and how? What are its quality ratings according to the 4Cs? For added security, you can laser-inscribe a personal message or the diamond’s unique GIA grading report number on the diamond’s girdle.


    Have your diamond appraised and insured. A diamond grading report describes the precise gemmological quality of your diamond, not its monetary value. For that, you’ll need to take your diamond and its report to an appraiser. And don’t forget to insure it, to protect your treasured heirloom.


    Like true love, a diamond’s light and brilliance won’t fade with time.
