The term “carat” refers to the weight and size of a diamond. The value of a diamond rises exponentially with its size. Most diamonds fall in between 0.01 carat and 1.00 in size. Put another way, that range is between a hundredth of a carat and a full carat in weight.
Carat Weight
Carat is the unit in which a diamond is weighed. One carat equals 0.2 grams or 200 milligrams. Carat weight is the prime factor that determines the weight of a diamond. Larger diamonds are undoubtedly costlier. Carat makes expressing diamond weight easier as compared to milligrams. Instead of giving three labels to diamonds weighing 20 milligrams, 211 milligrams and 220 milligrams, carat offers a category for fitting the diamonds in a one category, placing these diamonds in one-carat range.
One should not forget that high carat weight does not necessarily mean a larger looking diamond. Even diamonds of the same weight can differ on a basis of other factors, especially cuts that influence perceived size. Large diamonds are rare to find and much in demand as compared to small diamonds even of the same quality. The price of a one-carat solitaire diamond ring is more than a ring with smaller diamonds making up the same carat weight. Diamond comparison is not effective until you compare the diamonds of similar features and qualities. While comparing the value of different diamonds, divide the cost of every diamond in accordance with the carat weight and then calculate its price per carat.
You may have witnessed your jeweler discussing points while talking about diamond sizes. This is not in context with the number of facets a diamond has but to the weight of the diamond. One carat is equivalent to 100 points, so every point is 1/100th of a carat. Carat weight also influences a diamond’s price. Because of the rarity of larger stones, they are priced higher. Carat weight is an important consideration while buying the diamonds for your-self.
The clarity of a diamond is a measure of the number and type of inclusions within the diamond and on its surface. The fewer the inclusions visible under a 10X magnifier, the higher the clarity grade which ranges from flawless to heavily included.
Diamond clarity means finding out characteristics of a diamond, including the blemishes and inclusions. If you consider the pressure that a diamond is created, and that they are not produced in sterile laboratories, you will not be surprised to find that most of these diamonds are not free of flaws.
Usually there are two kinds of flaws found in diamonds – blemishes and inclusions. Inclusions are naturally occurring internal flaws that are found in diamonds including cracks, air bubbles, and minerals. However, most blemishes occur at the time of the cutting process. The diamonds that have less blemishes and inclusions are considered valuable as compared to those that have more.
On a basis of clarity, grades are given to diamonds under loupe magnification. These grades vary from the ones that do not have blemishes or inclusions to those that do. There are different grades given to a diamond like F, IF, VVS1-VVS2, SI1-SI2 and I1-I2-I3. Diamond’s clarity grade is proof of the identity of the diamond.
GIA certificates consist of a diamonds inclusion plot, as there is no similarity between two diamonds. The plot of the GIA certificate ensures the worth of the diamond you are planning to buy. It lets you have the assurance that the diamond you are receiving is the one you have paid for. If you are in a fix about what clarity grade you should choose, flawless is the best and rarest clarity grade.
Diamonds that are VS and VVS grades are great in terms of appearance and value. You can also invest in less expensive options that include SI2 and SI1 where inclusions can also not be seen by the naked eye.
