How much is a one-carat diamond worth?
Diamonds are known for their shine. However, when poorly cut, diamonds have little to no sparkle.Therefore, the price of a one-carat diamond varies depending on its cut. An example is that an SI1-G round diamond can be as low as $4,700 for a poorly-cut stone to as high as $9,300 for a very well-cut diamond.
Natural-diamond cost compared to lab-grown diamond cost
The cut of the gemstone is the most influencing factor on the price of a one-carat diamond. However, there is also a noticeable price difference between a natural mined diamond and a man-made diamond. On average, a laboratory-grown diamond will cost between 20 and 30 percent less than its natural counterpart.
In regards to this price difference, it is important to realize that man-made diamonds possess the same chemical and optical properties as mined diamonds. Both are authentic diamonds composed of carbon atoms aligned in the same signature crystalline matrix. Either type can be shinier than the next depending on its cut. Therefore, many people find the lab-grown diamonds a pleasant, eco-friendly alternative to earth diamonds.
Taking into consideration the 4 C’s
Color and clarity are often the key factors people remember to look at when shopping for a diamond. However, the cut of the diamond is equally important but more difficult for the non-professional to assess.
Cut quality simply refers to how well the professional who cut the diamond did in terms of polishing and placing the angles and facets. The cut quality of the diamond will greatly affect its sparkle and brightness. A poor cut will leave the diamond looking dull.
Carat is the term used for the measurement of the weight of a gemstone. While the carat number is a good indication of the size, it is not exact, as two diamonds equal in weight can be different in size.
Another term used for referencing carat is points. For example, a 1.0 carat diamond is equal to 100 points. Therefore, .50 carat is also referred to as 50 points or ½ a carat.
Whether or not a diamond has a tint is referred to as the color. Oftentimes, a diamond that appears colorless to the naked eye, does, in fact, have a slight tint. Colors that often appear in what is supposed to be a clear diamond include yellow, grey, and brown.
Colored diamonds are both found in nature, and made by laboratory processes. Colors most commonly seen in diamonds are red, pink, yellow, orange, green, and blue.
This term is in reference to the number of imperfections or inclusions within a diamond. About 26 different types exist and include gas bubbles, cracks, light or dark spots, etc.
According to the Gemological Institute of America (GIA) grading scale, a diamond can range from Flawless (FL) to Included (I3). Values reference 1 as the highest and 3 as the lowest. These are listed as subscripts and indicate the valuation within each grade.
