What is the Difference Between a Certification and an Appraisal? 2007-12-20 08:10:00 A certification is a survey of your gem that defines or grades certain features or qualities with internationally recognized values. These features are often known by the 4C acronym. An appraisal is a valuation or market price based on this specification. Read more:Certification

What Guarantee Does a Certification Give Me? 2007-12-20 08:09:00 There are numerous laboratories for certification. Two of the main ones are the Gemological Institute of America (GIA) and the European Gemological Institute. Here at Diamond Doctor we use the GIA exclusively, because that is the Gold Standard in the industry. Yes, they are more conservative. Often by quite a large margin, and that’s because they are a totally independent, non-profit laboratory staffed by 900 of the world’s leading diamond graders, scientists and educators, all with a mission to “ensure the public trust in gems and jewelry.”The GIA is the creator of the famous 4C’s of diamond value (color, clarity, cut and carat weight) and the birthplace of the International Diamond Grading System, now used as the industry standard. The GIA have graded all of the world’s reno Read more:Certification
What is Certification? 2007-12-20 08:09:00 Certified diamonds have been examined by independent experts and had their quality assessed and graded for, among other attributes, color, clarity and cut.

How to Buy an Engagement Ring 2007-12-10 23:07:00 You must first establish that the company that you are working with is a true wholesaler and that they sell only GIA certified diamonds.Certification is very very important, if you are not buying a GIA certified diamond rather don’t purchase a diamond at all. The GIA or Gemological Institute of America, sets the grading standards for diamonds worldwide and only true wholesalers sell GIA certified diamonds.

Ideal Diamond Cut - (Part 2) 2008-04-16 14:17:00 Diamond proportioning began in 1919 when a mathematician named Tolkowsky used numerical formulas to achieve the modern brilliant cut. He did this by cutting a diamond so that all light entering the stone followed a controlled path to exit the top of the diamond.In 1919 the diamond cutting industry was not advanced enough to apply Tolkowky’s mathematical angles and dimensions. Instead it used variations of the cut, based on what the technology of the time could do. As technology advanced, so did the ability to better approximate the ideal Tolkowsky cut, which provides the best return of light in a diamond. It is possible for an experienced diamond grader to estimate, within a decade, when an older diamond was cut by observing where on the technology timeline its proportioning falls and ho
Diamond Cut Introduction 2008-04-16 14:16:00 What makes one diamond sparkle while another looks lifeless and dull? A good diamond is dazzling, romantic and priced according to quality. The most important factor is the grading and evaluation of a diamond’s cut. The purpose of this lesson is to provide a basic understanding of the evaluation of cut and proportioning and how it impacts a diamond’s beauty and value.Parts of a DiamondParts of a diamond are named by the various facets.

Diamond Clarity Grading 2008-04-16 14:19:00 The least important diamond grade is clarity. Unfortunately, it is what many jewelers claim is most important, because it is the easiest to demonstrate. Anyone can put a diamond under a microscope and see if it has inclusions. It takes gemological knowledge to cut and/or color grade a diamond. Jewelry merchants with little or no formal gemology training often resort to a quick demonstration of clarity, which has made it the most important grade to many consumers. This could not be further from the truth.By definition, any grade diamond of SI2 and above requires magnification to see the inclusion. How often do your friends look at your diamond under a loupe? Since any diamond of SI2 clarity and up is considered "eye clean," meaning you must have magnification to see any inclusion, why worry Read more:Clarity
