Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Diamonds of premium cut are almost as good as ideal. While nature determines the color and clarity of a stone, diamond cut is dependent solely upon the skill of the cutter. Premium cut diamonds may be close to the ideal cut proportions and look just identical. Most people cannot distinguish between the two. However, there is a slight difference in quality and reduction in price over ideal cut diamonds.
Color Trained people can see yellow in a J color diamond pretty easily. You can also do this by placing the diamonds upside down on a white piece of paper and looking at them from the side. J-color diamonds offer an excellent trade off for price and quality - excellent choice for the budget conscious.
Clarity SI1 clarity diamonds are slightly included. SI1 diamonds have some inclusions visible under 10x magnification but not easily visible to the naked eye. A diamond with this grade of clarity is an excellent choice for someone on a limited budget.
