Every keystone diamond in the Oscar Winter collection is accompanied by a certificate from the Gemological Institute of America (GIA), the foremost international authority and most trusted source in diamond grading. Your GIA certificate not only ensures the authenticity of your diamond, it will also verify important details of your diamond that greatly influence its value, including the cut, clarity, color grading and exact carat weight.
But understanding a GIA certificate does not end with knowing the 4Cs of diamond quality. There are other factors included in this report that can significantly impact a diamond's optical properties, such as presence of florescence and depth percentage.
