The Essentials You Need To Know When Purchasing and Caring For Your Diamond.
Diamond Certification

Why You Need a Certificate

Purchasing a diamond should be an enjoyable and stress free experience, especially since buying a diamond often commemorates important, emotional and once in a lifetime moments. At the same time, a diamond may be one of your larger purchases and not making an informed decision can be a costly mistake. A diamond's market value is based entirely on its purity, quality of workmanship, and rarity. Fortunately, diamonds today are evaluated, valued, and traded using established industry standards and a uniform grading system commonly referred to as the 4C's. Using these standards, consumers are able to shop for, compare and select a diamond with relative ease. It's important however to insure that the diamonds you are looking at have been graded properly.

A Diamond Grading Report or Diamond Grading Certificate documents the specific characteristics of a diamond and is issued by an independent diamond grading laboratory. Having your diamond certified insures that it has been evaluated by a team of highly trained experts using the latest gemological tools and techniques. Reputable laboratories have well established and consistent methods and standards for grading. The reports that they produce provide a fair and unbiased comparison of diamonds in the market. Diamond grading certificates vary in their formats and the information provided, but all include the diamond's color, clarity, polish, symmetry, carat weight and dimensions.
