This beautiful diamond comes to you with this EGL package. You will receive the genuine EGL Diamond Analysis Report, signed and embossed with EGL's official seal of authenticity. EGL USA is one of the largest and oldest independent gemological institutions focusing on gemstone certification and research. Originally part of an international network founded in Europe in 1974, EGL USA opened its first U.S. lab in the heart of New York's international diamond and jewelry district in 1977.
EGL Diamond Analysis Report
The characteristics of the diamond in this report were based on the information gained from utilizing a variety of gem testing instruments. The following instruments were used as required to complete our examination: 10x magnification with a fully corrected loupe and binocular microscope, millimeter gauge, computer aided non-contact measuring device, spectroscope systems, Proportion Scope, electronic balance, master color comparison diamonds, ultraviolet light sources, fiber optic illumination, and other instruments. The diagram is an approximate representation of the type and relative position of internal and external characteristics. Red symbols indicate internal characteristics and green symbols indicate external characteristics
SIZE
Size in gemstones is measured in carats. One carat equals one-fifth of a metric gram in weight; it is the standard unit of weight.
SHAPE The shape in which a gem has been fashioned; i.e.: brilliant cut. Also refers to a gem’s proportions; i.e.: well cut.
CLARITY Clarity is the presence or absence of inclusions or flaws within a stone; one component of the “four Cs” used in grading stones. Clarity ranges from IF (Flawless) to I3 (Included). For clarity grades IF to SI (Slightly Included), inclusions are not visible to the naked eye. Diamonds with few inclusions are harder to find, thus more valuable than those with less clarity.
COLOR Color refers to the presence or absence of color in a white, as well as, fancy colored diamond. Color is one component of the “four Cs” used in grading stones. The most desirable diamonds are graded as (D thru F) and referred to as colorless. Even though Colorless are the most desirable, a light trace of yellow can look very beautiful when placed in a yellow gold setting; please keep the setting in mind when looking for the right diamond for you.
Secondary Hue The reference to the modifying tone of a gemstone, i.e.: an orangey red gem has an orange secondary hue.
Phenomina
An effect exhibited by a gemstone, such as a star, cat’s-eye, or adularescence.
MEASUREMENTS Measurements of a diamond are length, width and height. However when diamonds are described the following are considered measurements:
CUT Cut refers the depth and width proportions as well as the uniformity of a diamond’s facets. Cut is one component of the “four Cs” used in grading. This is a very important diamond characteristic because the angles and finish of a cut diamond determine its ability to reflect light and produce sparkle. Cut is not to be confused with a diamond's shape, such as Round, Radiant or Oval.
DEPTH Depth is the ratio of the total depth of the diamond, from table to culet, as compared with the total diameter. Depth is expressed as a percentage. For example, if the total diameter of a round diamond is 8 mm and the total depth is 6 mm, then the depth percentage is 75%.
TABLE Table is the ratio of the table width as compared to the total width. For rounds, the largest diameter is used. For fancies, the smallest diameter width used as opposed to length. For example, if the table measures 6 mm and the total diameter of the diamond measures 10 mm, then the table percentage is 60%.
GRIDLE Girdle refers to a specific part of a diamond, its outer edge or the widest part of the diamond forming a band around the stone.
SYMMETRY Excellent = E Very Good = V Good = G Fair = F Poor = P
Symmetry is the arrangement of the facets and finished angles; correspondence of form and constituent configuration on opposite sides of the center. The diamond cutter creates symmetry. Excellent symmetry of a well-cut and well-proportioned diamond can have a great effect on the diamond's brilliance and fire. Grading ranks symmetry in terms of Excellent, Very Good, Good, Fair, or Poor.
FLUORESCENCE None = N Faint = F Medium = M Medium Blue = M Strong = S Strong Blue = SB Intense Blue = IB
Fluorescence, in the science world is known as photo-luminescence. It is caused by a trace amount of the element Boron found in the diamond. It is activated by UV light. Fluorescence in diamonds is described as None, Faint, Medium, Medium Blue, Strong, Strong Blue and Intense Blue. Other colors of fluorescence do occur, yellow and white. One technique that gemologists use to help identify and separate diamonds from the diamond look-alikes such as cubic zirconia is by placing the gem under a UV lamp. If it glows blue, it is usually a diamond.
MEASUREMENT SIZES
POLISH V = Very Good G = Good P = Poor VP = Very Poor
Polish is very important to a diamond's brilliance; it influences how well light is able to pass through. Diamonds exhibiting poor to extremely poor polish are noticeably less brilliant caused by microscopic polish lines on the surface of the diamond that blue light.
