If your after an Engagement ring then your likely to stumble across the four C's. These are the CUT, COLOUR, CLARITY AND CARAT WEIGHT of a diamond.
The cut of the stone is probably the most important of the four C's. It's about how well a diamond’s facets interact with light, so its proportions, symmetry and polish deliver the best return of light. Each stone is evaluated on how successfully it interacts with light to give the best visual effects such as brightness and sparkle.
When we talk about Colour in diamonds, we are really talking about the absence of colour. The colour range starts from D, being a colourless stone, all the way to Z which we would call a light colour.
The Clarity is another very important factor when choosing a stone. Diamonds are made of carbon which has been exposed to very high temperature and pressure. Small inclusions can be left either internally or on the surface of the stone. These inclusions can be a black spot, feather, cloud, crystal etc... Depending on the number, nature, size and position of these inclusions as well as how it effects the overall appearance of the stone will determine the final value of the diamond.
- Flawless (FL) No inclusions under 10 x magnification.
- Very, Very Slightly Included (VVS1 ,VVS2) Inclusions so slight they are difficult for even a diamond grader to see under 10x magnification.
- Very Slightly Included (VS1 , VS2) Minor Inclusions are observed with effort under 10x magnification.
- Slightly Included (SI1 , SI2) Inclusions are noticeable under 10x magnification.
- Included (I1, I2, and I3) Inclusions are very obvious under 10x magnification.
Diamond carat weight is the measurement of how much a diamond weighs. Each carat can be divided into 100 points, so a quarter of one carat would equal 25 points and a half a carat 50 points and so on. sometimes with small diamonds a total diamond weight is given, an example of this might be .25ct TDW (Total diamond weight), which simply means this is the total weight of all the diamonds in the ring.
