REPORTS

Every Diamond Report provides:
Information on the stone’s identification: diamond/imitation, natural/syntetic, treated/not treated.
Analysis of the 4C’s Color, Clarity, Cut, Carat weight.
The color of the diamond is graded in a neutral environment created specifically with the correct lighting using only diamond Masterstones. The clarity is graded at a standard 10x magnification. The first step is to observe and evaluate the clarity characteristics and, based on their visibility, express a degree of purity. The cut is graded based on both the visual estimation and the analysis of the proportions, the finish and symmetry. The visual estimation comprises the brilliance, fire and scintillation (pattern). The diamond’s proportions, together with the shape of the diamond, help to increase the visual yield. The weight of a diamond is determined by high-precision analytical electronic scales which measure weight to the fifth decimal place.
Plot: The plot is the graphic representation of all the clarity characteristics of the diamond.
Proportion Diagram: All the proportions and measurements relevant to the geometry of the diamond are shown in the proportion diagram.
At the GECI laboratory, analyses are performed on loose diamonds starting from a weight of 0.10 ct . In addition to the classic Diamond Grading Report, you can receive, upon request, a Diamond Report, a shorter analysis document, which always has the details of the 4Cs, but without diagrams related to the clarity characteristics and the proportions.

Every Colored Stone Report provides:
Gemstone Identification: species, variety and, where required, group. Whether the gem is natural, synthetic, artificial or treated is also specified in the report.
Treatments: The presence, type and extent of the treatments are examined extremely carefully.
Gemstone Grading: Analysis of the color, weight, measurements and cut of the gem.
The color is evaluated in the standard viewing environments, with adequate lighting and compared with Masters (a Munsell set with more than 50 master stones). The weight of the gem is measured by a precision electronic scale, which measures it to the hundred thousandths of a carat. With the term ‘size of a stone’, the length, width and depth and the cut refers to the proportions, which have a primary effect on the appearance of the gem and its color.
GemstonesOrigin Opinion::Identification of the geographical origin of the gem. This service is available only upon request. Our staff, following a very strict procedure, is able to express an expert opinion on the geographical origin of rubies, sapphires, emeralds, and other varieties or species.

Every Pearl Report provides:

Pearl Identification: pearl/imitation, saltwater/freshwater, cultured/natural, treated or not.

Grading/ 7 factors analysis:Complete analysis of the 7 pearl value factors (size, shape, colour, luster, surface quality, nacre quality, matching –where applicable).

A Jewelry Report can be issued for pieces of jewelry with one or more diamonds and/or colored gemstones and provides information about:
– Number of gemstones, identity and main characteristics (carat weight and color)
– Presence of diamonds, and their clarity, cut, color and carat weight.
– Metal stamps present on the jewel.
– Weight of the jewel in grams.
The GECI lab, thanks to its highly advanced equipment, can analyse antique jewels as well.
