Diamond basics
Choose your favorite diamond shape. Most diamonds are cut into the round brilliant shape, but there are many others to choose from.
The 4C's of a diamond determines its beauty & value.
The clarity, colour, cut and carat weight of each diamond is graded by a Gem Scan certificate, Canada's largest gemmological laboratory. Gem Scan is accepted by all Canadian insurance companies.
Diamonds are cut into many shapes. The most popular eight shapes are:

A diamond's weight is the easiest of its characteristics to measure. The word carat originates from the natural unit of weight of a carob tree seed. A 1 carat diamond used to equal the weight of a carob seed, but today the carat is a metric weight of 0.2 grams, or 1/42 of a standard ounce. Each carat is divided into 100 points. A quarter carat diamond = 25 points, or is written as 0.25 ct. A half carat diamond = 50 points, or is written as 0.50 ct.
Most diamonds contain tiny identifying marks called inclusions. The fewer and smaller the inclusions, the less likely they will interfere with the stone's beauty. Minute traces of other minerals trapped during the formation of diamonds cause many of these inclusions. The number, color, nature, size and position of any inclusion determines the clarity of a diamond. The fewer the inclusions, the rarer it will be graded, and the more light it will reflect, thus making it more valuable.

Diamonds come in many colours, but the majority used in jewellery are near colourless to very light yellow or brown. The best colour for a diamond is totally colourless, this allows white light to pass through it, and is dispersed as a rainbow of colours. Most diamonds look colourless, but there are many subtle shade differences and the closer a diamond is to having no colour the more valuable it becomes.

The way a diamond is cut and polished dictates the maximum amount of light the diamond will refract and reflect. The better it has been cut, the greater will be its brilliance, sparkle and fire. When a diamond is cut to good proportions, light is internally reflected from one facet to another and then dispersed through the top. If the cut is too deep or shallow, some light will escape through the sides or bottom, and will adversely effect a diamonds brilliance.
The clarity, colour, cut and carat weight of each diamond is graded by a Gem Scan certificate, Canada's largest gemmological laboratory. Gem Scan is accepted by all Canadian insurance companies.
