All Solitaire Club’s Diamonds are GIA graded.
Expert detailing and mathematical wizardry is taken care by our world class professional gemologist team to ensure each Solitaire Club diamond meets our stringent technical requirements. Our commitment to the quality that is further guaranteed by GIA certification for every Solitaire Club diamond.
Before GIA created the 4Cs of Diamond Quality and the International Diamond Grading System™, there were as many ways to describe diamonds, as there were methods for evaluating their quality.
Then in the 1940s and 50s, GIA transformed the way diamonds were bought and sold by doing three things:
| 1. | Creating a common language for diamonds. The 4Cs and the GIA International Diamond Grading System™ provide a consistent way to describe a diamond’s characteristics. |
| 2. | Establishing the methods and best practices used to grade diamonds. |
| 3. | Issuing the first GIA Diamond Grading Report, as a way to consistently and accurately communicate grading results. |
GIA’s innovations have been adopted universally. In every corner of the world, virtually every diamond is described using the language GIA developed.
The GIA Diamond Grading Report contains scientifically determined information on diamond shape, color, cut, clarity, carat weight, proportions and finish. It also identifies any known treatments. Other reports from other entities have since made their way into the marketplace, but GIA is recognized as the original and unrivaled source for accuracy and integrity in diamond grading.
The GIA Diamond Dossier® is a more concise, compact version of the GIA Diamond Grading Report and is available for diamonds that weigh between 0.15 and 1.99 carats. This report includes all the important 4Cs grading results as the Diamond Grading Report, but does not include the plotted diagram. GIA also offers online-only reports with full 4Cs grading results: the GIA Diamond eReport and the GIA Diamond Focus™ Report.
As an added security measure, GIA also offers optional laser inscription with its reports (included with the Diamond Dossier and Diamond Focus Report) where the diamond’s report number is inscribed on the diamond’s girdle. GIA can also inscribe customized messages, dates, text and symbols that not only personalize a diamond, but allow for easy identification.
GIA exists to connect people to the understanding of gems. As a long-standing scientific authority, GIA is not only a unique source for diamond knowledge, its grading reports inspire confidence wherever they appear.
GIA’s commitment to protecting diamond buyers inspired the Institute to create the Diamond 4Cs and the International Diamond Grading System™. These methods are the universal benchmarks by which all diamonds are judged. As the birthplace of these standards, and with its investment in continued gemological research, GIA’s authority is unequaled.
The world’s most respected retailers, museums, auction houses and private collectors rely on the expertise of GIA graders to assess, grade and verify their gems. They recognize the importance of complete, unbiased, scientific information in gem assessment, and absolutely trust GIA to provide it.
‘Ensure the public trust in gems and jewelry by upholding the highest standards of integrity, academics, science and professionalism through education, research, laboratory services and instrument development.’
GIA’s founder, Robert M. Shipley, had a tremendous impact on the world of gems. Shipley recognized the need for a comprehensive, international approach for understanding and evaluating gemstones. Without it, confusion and distrust would reign both at home and abroad. Shipley founded the Gemological Institute of America in 1931, not only as a place for gemological study and research, but also as an educational facility where gem knowledge could be organized and shared with the public. His goal, and the Institute’s enduring principles, are clearly reflected in GIA’s mission statement:
