Easily mistaken as the shape, the diamond cut refers to the diamond symmetry, proportions and polish. When a diamond is cut, is the positioning of the facets what will modify how much light enters and how much is reflected.
The cut will determine how a diamond interacts with light, creating an extraordinary show of lights. A diamond’s cut is the most important factor to consider when choosing a diamond since it will affect on the diamond’s sparkle
How Light Passes Through The Diamond
Please view the diagram below, which illustrates how light passes through different types of cuts.
Types of diamond cut:
Ideal CutThis type of cut reflects almost all the light that enters the diamond.
Excellent CutThis cut reflects nearly as much as the ideal cut.
Very Good CutA great cut since it reflects most of the light that enters the diamond but is priced much lower than the excellent cut.
Good Cutthis cut reflects most of the light that enters the diamond but it will not have the sparkle and brilliance that the other cuts have.Good cuts are a great option for when you are on a budget.
Fair Cutthis cut will reflect a small portion of the light that enters the diamond, usually because the stone has been cut too deep or too shallow.
How to choose the perfect diamond cut?
When in doubt, always go for a higher diamond cut because it will have a better brilliance and scintillation. Also, a higher cut will make your diamond look visually larger than its carat weight.
Clarity refers to the purity or cleanliness of a diamond. This is determined by the number of inclusions a diamond might have and is determined by a gemologist, who inspects the diamond with a 10x magnification glass.
The Diamond Clarity Chart
Measured on a scale from Flawless (FL) or Internally Flawless (IF) to Included – I1, I2 and I3 – this diamond clarity chart helps you choose the best diamond. Just remember, the more internally flawless a diamond is, the sparkler is going to be.
How to choose the perfect clarity grade?
Everything will depend on the diamond shape and carat you are going for. For example, if you choose a Brilliant cut like Round, Princess or Oval, you can get away with choosing a lower grade because this shape helps hide inclusions better than step-cut diamonds like Emerald or Ascher. If you are going for a step-cut, always select a higher clarity grade.
It may sound paradoxical but when we talk about a diamond’s colour we are actually referring to the absence of colour in the diamond itself. The whitest or colourless a diamond is, the more light will pass through the stone which will create an extraordinary sparkle.
The Diamond Colour Chart
Measured on a scale from D – E – F (colourless) to X-Y-Z (light yellow), this diamond colour chart will help you chose the perfect diamond for you. Bear in mind that a colourless diamond will be a sparkler diamond.
How to chose the perfect colour?
If you like your diamond to be as perfect as you can get, then choose a diamond in the range of D-F, which will be colourless.
If you are concerned about your budget, you can choose a G-I diamond, the yellow tone will be hardly noticeable.
A carat is a unit of mass used to measure the weight of a diamond or gemstone.
Diamond Carat Size Chart
To determine a diamond or gemstone’s weight, each stone is weighted individually. One carat is equivalent to 200 milligrams, or 0.2 grams.
It is important to bear in mind that, while carat weight can influence the price of a diamond, no two diamonds of the same weight will worth the same. Each diamond is valued by taking into account the 4 C’s: Carat, 8Cut, Colour and Clarity.
Which carat weight should I choose?
When deciding on a diamond engagement ring, most couples will focus on the carat weight of the diamond. A 1-carat diamond is one of the most popular choices, however, if you are on a budget look for diamonds that fall just under these popular carat weights. For example, instead of choosing a 1-carat diamond, go for a 0.90-carat. They look almost the same but the price will be significantly lower!
We have created a chart with our most popular design so you can see the difference between a 2-carat, 1-carat, 0.90-carat and a 0.50-carat.
