Confidence shall support you in that dream proposal you intend to make or in wearing an authentic gem. To ensure you have this confidence, make sure that the loose diamond you have chosen is GIA certified. A GIA certified loose diamond is a gem that passed through the evaluation of an expert gemmologist in the Gemmological Institute of America (GIA). This is a reputable and reliable laboratory that conducts gem evaluation. It has set the standards for documenting diamond quality worldwide. It issues reports for most of the high quality diamonds more than one carat size. It uses the Diamond Grading System which it also developed. The GIA certificate indicates details and characteristics of the loose diamond which may not be visible to the naked eye. A 10x magnifier is used to look for inclusions and blemishes. This certificate provides the assurance of the quality and authenticity of the stone. It also specifies the stone is worth the amount you have paid for. You may be an inexperienced buyer of diamonds; however the GIA certificate helps in providing an objective comparison. The stamp of genuineness shall indicate a fair price specially when reselling the stone. To further ensure that this stamp of approval is original, the GIA certificate contains the following information. - Initial information includes the date when the assessment was made and GIA report number. - Upon your request, a micro laser inscribes the laser inscription registry with its unique GIA report number. - Symmetry, shape and cutting style are identified. Symmetry is the diamond's outline and shape exactness, placement and alignment of facets. Shape shows the outline of the diamond and cutting style specifies the pattern of facet arrangement.
