Jewellery Garden most of the jewels are setted with natural diamonds. You can find out that every jewellery piece in JewelleryGarden.uk has its own short description where you see what is the quality of diamonds: color, clarity and total carat weight. See the example here.
GIA (Gemological Institute of America) created globally accepted standards for describing diamonds: color, clarity, cut and carat weight. Today, 4Cs of diamond quality is the universal method to grade and valuate diamond anywhere in the world.When Four Cs are used together, they describe the quality of a finished diamond, which is directly related to its value. Below, we prepared for you 4Cs in a simple and informative way to help you to understand diamond quality in more detail.
The D to Z scale describes the normal color range of diamonds, it is an industry standard scale for color grading diamonds. Each letter represents a range of color based on a diamond`s tone and saturation. Color range from D – colorless, which is the most rare and valuable to Z – light yellow or brown. The closer a diamond gets to colorless, the higher its price. Diamonds also can come in almost any color you can imagine: red, green, purple, orange, pink, blue, yellow and brown which are outside the normal color range and are called fancy colored diamonds.

The clarity scale includes eleven diamond clarity grades which are flawless, internally flawlles, very very slightly included (VVS1 and VVS2), very slightly included (VS1 and VS2), slightly included (SI1 and SI2) and included (I1, I2 and I3). See the scale below. Diamond clarity characteristics can be either blemishes or inclusions. The difference between inclusions and blemishes is based on their locations. Inclusions are enclosed within a diamond, they might also extend into the diamond from the surface. Blemishes are confined to the diamond`s surface. Diamonds with no clarity characteristics are more rare and more valuable than diamonds that have just a few. Jewellery Garden most of diamonds are SI and VS quality. SI1 and SI2 diamonds have some internal inclusions, which you can not really see them unless you look at the diamond under magnification. Inclusions make a diamond unique, special and affordable. VS1 and VS2 diamonds have one or two minor inclusions that are invisible unless you look at the diamond under magnification, they are very nice diamonds that you can really be proud to posses.

The cut grading system gives you an easy to understand way of explaining why diamond looks the they it does. There are five cut grades: Excellent. Very Good, Good, Fair and Poor. Diamond with excellent cut grade gives a maximum amount of light reflection then diamond with poor cut grade lose most of light out the sides and bottom. Most of Jewellery Garden diamonds are very good cut grade, which reflect nearly as much light as excellent cut.

Diamond Carat Weight
A diamond’s size is indicated by its weight, and the weight is indicated in carats: one carat equals 1/5 of a gram or 0.200 gram. The word carat is often abbreviated as “ct.” If a diamond weighs less than one carat, its weight is indicated in points (1/100 of a carat). Therefore, a half-carat stone weighs 50 points, while a 75 point diamond is 3/4 of a carat. If a diamond weighs more than one carat, its weight is expressed in carats and decimals. Therefore, a 1.07 ct. stone weighs one carat and 7 points. The larger a diamond, the more rare it is. Therefore, as carat weight increases, so does the price per carat. A 2-ct. stone, for example, will be more than twice that of a 1-ct. stone, assuming they are similar in cut, clarity and color.
