QTell me about the 4 C'S ?
A- The first step in helping to our customers choose diamonds is to clearly convey the meaning and importance of the 4C'S; COLOR, CUT, CLARITY, and CARAT WEIGHT. These four variables are used to calculate the value of DIAMOND.
COLOR - describes the amount of color the diamond contains. This can range from colorless to yellow with slight tints of yellow , gray or brown. Colors can also range from intense yellow to brown, blue, green, pink and red. This fancy colors are rare and therefore more valuable. Colorless diamonds are the most desirable since they allow the most reflection of light. Best to observe diamond color by placing the stone table-side up on flat white surface or grading through, and examining from different angles.
CUT - has the greatest Influence on the diamond's fire and brilliance. A round, brilliant-cut diamond has 58 facets. When well proportioned, this shape best shows the stone's brilliance because it allows the most light to be reflected back to the eye of the observer. Stones that appear lifeless or seem dark in the center are probably poorly cut.
CLARITY - describes the clearness or purity of a diamond. This is determined by the number, size, nature and location of the internal (inclusions) and external (blemishes) imperfections. Perfect clarity means that no inclusions are discernible when the diamond is examined under a 10X lens.
CARAT WEIGHT - The term carat comes from the ancient practice of weighing diamonds against the seeds of the carob tree. The system eventually standardized, and one carat was fixed at 0.2 grams. One carat is a 100 points, so a quarter-carat diamond is 25 points or 0.25 carat.
