Carat Weight

Diamonds and other gemstones are weighed using metric carats with one carat weighing about 0.2 grams. It is important to note that two diamonds of equal weight can have very different price values depending on the other characteristics of a diamond’s 5Cs: clarity, colour, cut, and crystal structure.

Global Diamond’s tip:

Never sacrifice quality for size. There is nothing worse than your partner having to continually tell her friends that her diamond doesn’t sparkle because it needs a clean. A diamond with great fire and sparkle will look visibly larger to the eye than a diamond with no lustre. A diamond’s size should be the last piece of the puzzle. Once you have chosen the right grades for yourself, the size of the diamond should be dictated by the budget you have set.

We have also had clients say they saw a 1.00 carat diamond that looked a lot bigger than another 1.00 carat diamond. What this simply means is that the particular diamond was cut with a very wide table, but a very shallow depth. This type of cut may make the actual diamond size look big, but the poor cut proportions will make the diamond look dull and lifeless. It is far better to have a diamond that is cut properly to the correct proportions, as this gives the diamond life and fire.

Another very important issue to note with carat weight is when jewellers talk about total carat weight. This is the total weight of all diamonds within the piece of jewellery. It should be strongly noted that diamonds go up exponentially in value the bigger they get.  Therefore, several small diamonds that make up a 1.00 carat total are far less valuable than one large diamond that weighs the same amount.
