4Cs of Diamond - Larry Jewelry

4Cs of Diamond

With the reputation of “A Legend of Fine Jewelry” in Asia, Larry Jewelry has performed strict inspections to ensure each diamond meets the 4Cs standard (cut, color, clarity and carat) and creates an incredible brilliance from diamonds.


Cut does not refer to the shape of diamond, but the proportions, symmetry and polish of the diamond. It is the most important “C” as it determines the beauty of a diamond. All diamonds at Larry Jewelry have gone through stringent selection for their ideal cut requirements. Only diamonds cut in accordance to the strictest ideal cut produce maximum brightness, scintillation and fire. According to Gemological Institute of America (GIA), the diamond cut contains five grades ranging from excellent, very good, good, fair to poor.


The scale for diamonds ranges from colorless (D-color), the rarest and the most valuable to the lowest grade, light yellow (Z-color). Diamonds are color-graded by comparing a stone under controlled lighting and precise viewing conditions to “masterstones” of established color value. A more colorless diamond has a higher value. At Larry Jewelry, only high color diamonds are selected.


Clarity is the degree to which natural marks of inclusions or blemishes are found in most diamonds under 10x magnification. The GIA Diamond Clarity Scale is the most universal grading scale; the evaluation involves determining the number, size, relief, nature, and position of the inclusions and blemishes, as well as how these affect the overall appearance of the stone. Its grading ranges from the highest value “FL (Flawless)”, to the lowest value “I3 (Included)”. Diamonds without these marks are rare, and rarity affects a diamond’s value. With above average clarity ranging from FL to VS2 (Very Slightly Included), Larry Jewelry offers a variety of fine diamond collections for your selection.


Carat refers to the diamond’s weight, and one carat is divided into 100 points, one carat is also defined as 200 milligrams. Diamonds of equal quality can vary in value since the size of diamond affects its price, the higher the carat weight, the larger and rarer the stone is. At Larry Jewelry, our sales professionals are always pleased to help you to analyze all of the complex factors – cut, color, clarity and carat – to arrive at the best quality combination of your choice.
