As Canadians, we should all be very proud of owning the oldest (3 billion years) and prettiest diamonds in the world. They have more value at the time of appraisal than any other origin.

Speaking of origin, Canada is the only country in the world that has traceable diamonds. This means if you purchase a Canadian diamond, it will be engraved with a maple leaf, or Canadian diamond logo, and have a traceable number (this does not include melee, which are very small diamonds used as accent stones). So, if someone is selling you a Canadian diamond, you can check its authenticity before you purchase it and have peace of mind that you are buying the real deal.

With all the different sources for natural diamonds available, as well as laboratory-grown diamonds, isn’t it nice to know your diamond was ethically sourced using an environmentally friendly process, right here in your backyard?

Speaking of “environmentally friendly” diamonds, there seems to be a misconception about laboratory-grown diamonds. The advertising for these stones can be misleading, with the idea that they are more environmentally friendly than mined diamonds. Unfortunately, that is not the case. Laboratory-grown diamonds need a lot of water and power to artificially create a diamond in a short period of time. Today’s natural diamond mines must adhere to strict environmental guidelines to operate. They must return the land to its original state after completing their mining operations. They also create many jobs for Canadians.

Diamonds are fascinating. Pink diamonds are the rarest ones in the world. The only existing pink diamond mine in the world, Argyle Diamond Mine in Western Australia, is now closed after over 30 years of mining. This makes natural pink diamonds even rarer… and desirable. It’s no wonder they are sold as investment stones since they have never lost their value in over thirty years. Their value actually goes up substantially, now more than ever.

Although diamonds exist naturally in browns, yellows, oranges, reds, blues, and greens, they can be treated to be any of these colours. The value of a treated coloured diamond is far less than a naturally coloured diamond. Be sure you understand what you are buying as some of the lingo is not always straightforward. “HPHT” and “CVD” for example are disclosures that don’t make much sense if you are not familiar with the industry lingo. Both HPHT and CVD are treatments to diamonds that improve their clarity and/or colour.

Diamonds are the hardest gemstone on earth, a perfect “10” on the Mohs hardness scale. This does not mean they are indestructible. If your diamond has many inclusions or has been treated, it can chip or break if placed in an ultrasonic cleaner. Warm, soapy water is always a safe alternative.

One last word on natural diamonds: You get what you pay for, there are no deals with diamonds. Do not compare paperwork and grading reports. It is always better to see your diamond before you buy it.
