What is Certified?
JB Hudson offers a great selection of certified diamonds. A certified diamond is one that has been graded by an independent laboratory and has a document that was issued stating its grade. There are many certification labs and they are not all equal. The highest regarded laboratories grade more strictly and the diamonds graded by them are valued higher because of this.
The Gemological Institute of America, often referred to as GIA, and the American Gem Society (AGS), are the highest regarded labs in the world.
JB Hudson carries diamonds graded by both GIA and AGS. However, a diamond with any preferred grading report is available.
How GIA Grades Your Diamond
Independent and nonprofit, GIA is considered the final word on a diamond’s authenticity and quality. GIA developed the 4Cs and the International Diamond Grading System; the grading standard adopted by jewelry professionals around the globe.
GIA screens every gemstone to identify synthetics, simulants and known treatments. Expert gemologists examine each diamond under controlled lighting and viewing conditions, in order to provide the most rigorous assessments of a diamond’s 4Cs.
Every GIA Diamond Grading Report or Diamond Dossier contains these assessments along with additional descriptive information and state-of-the-art security features. Regarded as premier gemological credentials by international gem professionals and fine jewelry houses, GIA Reports accompany the world’s most legendary diamonds, and now, quite possibly, yours.
