Larger diamonds are found in nature with much less frequency which makes them more valuable. Hundreds of tons of rock and ore must be processed to uncover a single one-carat gem quality diamond, and less than one percent of all women will ever own a one- carat or larger diamond. Since a carat is a unit of measure and not size, two diamonds of the same carat weight may appear to be different sizes depending on how the diamond is cut.
Do not be mistaken by the belief that the larger the carat weight, the more valuable the diamond.
When selecting the best carat weight, take into consideration such factors as your preference in diamond shape, the type of jewellery the diamond will be used in, if it is for a diamond ring then another factor such as finger size would also have to be thought of. Finding rough diamonds is increasingly rare with size: for every million pieces of rough material only one piece on average is large enough to produce a 1-carat finished diamond. A regression analysis of available diamonds shows carat weight accounts for the biggest portion of the diamond value, followed by color and clarity. In a graph below you can see how fast the price per carat jumps with diamond weight moving from one carat weight bracket to another. Most recommend a cut rating of Excellent or Very good and at the very least Good if on a budget. The Princess diamond is the next-most popular diamond cut next to the Round Brilliant cut diamond. The upside is that Princess diamonds tend to have a lower price tag than the Round Brilliants of the same carat weight because the Princess’s yield is much, much higher than the round brilliant cut. In terms of recommendations, you need to be a little more careful with picking the color than you would with the Round Brilliant because it isn’t as superior at hiding the true color as the Round Brilliant is. The cut is all about how the diamond reflects light — it’s what makes a diamonds really flash and sparkle.

All levels from F-SI have slight inclusions that are only visible under 10x magnification, meaning the flaws aren’t really visible to the human eye. A three-carat (3.00ct) diamond is always more expensive than several diamonds which add up to make three carats in total weight. Some diamonds will have extra weight on the bottom part of the diamond, the pavilion, and therefore will appear smaller visually. Then there is the type of setting and the design of the piece of jewellery, with regard to your taste, style and fashion at the time of purchase. During the cutting process, a diamond typically loses 40% to 60% of its original rough diamond size.
Still, a poorly crafted large diamond can be worthless compared to a much smaller, well crafted stone.
The Round Brilliant is now probably the most popular diamond in the world, representing about 75% of all diamonds sold. You can be flexible with the cut, color and clarity grades of the diamond to fit your budget without really sacrificing fire and brilliance. The shape is more square or rectangular and looks like an upside down pyramid with rounded corners. Many recommend at least an H Color or I color for the best value, and nothing below J color.
These are more desirable and thus more highly priced. GIA uses a D through Z alphabet scale to grade colorlessness in diamonds, starting with D (for colorless) and increasing in color content until Z (color). The chart below outlines various diamond weight sizes and the corresponding milimetre size. Keep in mind that a diamond's colour, clarity and cut are major factors that influence the value of a diamond. And more importantly is your budget for the diamond, as this will dictate a lot of the 4C's and then you can adjust accordingly for size, colour, clarity and diamond shape, as some diamond shapes on a per carat basis are more expensive than others. The word “carat” originates from the Greek word ker?tion, which means carob beans, which were known in the ancient world for uniformity of their size and weight and were used as a measure of weight for different objects, including gemstones.In the Far East instead of carob beans jewelers used rice grains to determine the weight of gemstones.

They tend to cost more because the demand for them is so high and the yield (the amount of diamond left after cutting) is so low. For clarity, just be careful if the inclusion is on any of the diamond’s corners because that will make it more prone to chipping.
Each of these has a universally used grading scale determined by the Gemological Institute of America (GIA).
D-F are colorless, G-J are near colorless, K-M are faint yellow, N-R are very light yellow, and S-X are light yellow. Traditionally diamonds and gemstones were weighed against these seeds until the system was standardized, and one carat was fixed at 0.2 grams. Most importantly the diamond you decide upon should be one that you love and will cherish forever.
Because of this fact, you may occasionally hear some jewelers referring to a 1-carat diamond a “four grainer,” which means in the past 1 carat was equal to four grains of rice. Finally, the cut, for this diamond is a little tricky because the Gemological Institute of America (GIA) does not grade the cut of this diamond. Diamonds between G and I will virtually show no color to the naked eye, are thus priced higher.
J-M will have be very, very faintly yellow and the color can actually be minimized depending on the jewelry the diamond is mounted on. A diamond weighing one quarter of a carat can also be described as weighing 25 points or 0.25 carats.
If you need other opinions to cross reference, the Accredited Gem Appraisers (AGA), American Gem Society Laboratory (AGSL) and European Gem Laboratories-USA (EGL-USA) do offer cut grades. Carat is often confused with size of a diamond even though it is actually a measure of weight, a diamond's size is measured by fractions of millimetres.
