Sounding like a diamond expert can be a lot easier with a few basic terms. The 4 C’s, Cut, Clarity, Color and Carat are the basics which we’ve discussed at length in previous blog posts. But another piece of terminology that diamond pros use are “points” or “pointers”.
When diamond experts refer to diamonds, they will call it a certain number pointer like “a 50 pointer” or “a 75 pointer”. This number does not refer to the amount of different flat surfaces (also known as facets) on a diamond. The number relates to the amount of carats in a diamond. From a mathematic standpoint, 1 carat equals 100 points. So if someone calls a diamond a “50 pointer” they are saying the diamond is half a carat.
As discussed previously, the amount of carats does not refer to the size of a diamond, but to the weight of a diamond. One carat equals 1/142nd of an ounce or 1/5th of a gram.
As discussed previously, carat weight is not the key component of a diamond. The diamond’s cut has a lot to do with how it sparkles. The diamond’s color, whether a white diamond or a fancy color diamond relates to it’s beauty. The diamond’s clarity relates to whether it has any cracks or inclusions within the stone. It is these four factors combined that dictate a diamond’s true value.
So you may never become a diamantaire with your own personal loupe in your back pocket, but you can at least sound like one.

Most people can name the top 5 diamond producing countries in the world. Russia…check. Australia…absolutely-check. A trio of African countries Botswana, the Democratic Republic of Congo and South Africa…check, check and check. But did you know Canada is #6 in the world?
What’s interesting about Canada’s place in the diamond world is that the precious stones were not found until the mid-80s with working diamond mines popping up less than a decade later.
Canada has never been a place to find excessively large diamonds, the largest one ever found is a 35-carat stone recovered from the De Beers Victor Mine near Attawapiskat in Northern Ontario in 2013. The diamond was purchased, cut and polished by Vancouver diamond maker Crossworks.
Currently there are five mines in operation in Canada. Three are located north of Yellowknife in the Northwest Territories: the Diavik Mine, the Ekati Mine and the Snap Lake Mine. The aforementioned Ontario-based Victor Mine as well as the Jericho Mine in Nanuvut are the other two Canadian mines.
The most recent star of the Canadian diamond world is this 11-carat rough diamond recovered from the Ekati mine. The stone is currently on display at the Royal Alberta Museum as part of their mineral collection.
According to Melissa Bowerman, assistant curator of geology for the facility, the diamond is going to remain on display as a permanent feature of an expanded mineral exhibit when the new downtown Edmonton location opens as western Canada’s largest museum in December 2017.
