Some diamond mines separate diamonds from the broken rocks by running the material over a conveyor belt covered with a layer of grease. If you do buy a piece of jewelry and are concerned that it may contain nickel, commercial test kits are available online. Doing a little research can prevent a nickel allergy attack and still allow you to wear any fashion.
Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Diamonds of fair cut quality are still quite attractive, but they may not be as brilliant as the top 3 grades. Fair cut diamonds are proportioned to yield more carat weight from the diamond rough. Such diamonds may be attractive to budget-conscious customers.
Color In the near colorless category H color grade is the second best. Most H color diamonds have a very light yellow or gray tint that may be more noticeable when the diamond is placed on a white surface. Diamonds with H color grade appear white and are great values because they are more plentiful and as a result less expensive.
Clarity Diamonds of VS2 clarity have very small inclusions grade two. Inclusions VS2 diamonds are somewhat easy for a skilled grader to locate under 10x magnification. Diamonds that are graded VS in clarity are still very impressive looking diamonds under a microscope. Of course nothing is visible at all to the human eye. Such diamonds have a great balance between good clarity and exceptional price.
