1. Carat Weight
Most people assume that carat weight refers to the size of the diamond. As the name suggests, carat weight is a measurement of weight, not size. This means that every 1.00 carat diamond will not be exactly the same size. If you are comparing two diamonds, review the measurements of each. In this way, you can easily determine which will visually look bigger to the naked eye.
The overall shape of your perfect diamond is an aesthetic choice. The illustration below shows some cuts (or shapes) for you to choose from:
How well it is cut:
No matter what shape you choose, how well a diamond is cut will determine how much sparkle, brilliance, fire and scintillation are reflected back to your eye. This is where your trusted advisor at Perrara can help. We will walk you through what the cut of each diamond you are considering is and how it equates to the value or price of that particular diamond.
The illustration below shows several depths of a traditional round brilliant cut and how this affects the light moving through it. A well-cut diamond will have the maximum amount of light reflecting back to your eye.
Diamonds come out of the earth in a multitude of colours, including vivid pinks, warm chocolates and crisp blues. However, the most common colours are clear (or white) to yellow. Diamonds in this range are graded on an alphabetical scale starting with D and continuing to Z (D being the clearest diamond lacking in any tint of colour). The clearest diamond will have the most value, and therefore the highest price tag. The illustration below shows this colour chart in more detail:
The last (but not least!) C is clarity. Clarity refers to the flaws (also known as inclusions) inside a diamond. Flaws or imperfections are graded based on their size, amount, type and relief (or how visible they are). These factors will significantly affect the grading and pricing of a diamond. Below is the chart that an experienced diamond grader will use to determine the clarity of a diamond:
