shape
carat
Carat
A carat is a metric unit for measuring the weight of a diamond. 200 mg (0.2 grams) equals one carat. Despite the fact that carat weight and diamond size are linked, the carat does not directly measure diamond size.
price
cut
cut
The angles and dimensions of a diamond are referred to as the cut. The beauty of a diamond is determined by its cut—its depth and width, as well as the uniformity of its facets. The ability of a diamond to reflect and refract light is determined by the expertise with which it is cut.
color
color
Color refers to a diamond's natural color, which does not alter over time. Color-less diamonds transmit more light than colored diamonds, leading to enhanced sparkle and fire.
clarity
clarity
The presence of imperfections on and within a diamond is referred to as clarity. Tiny traces of natural components are typically generally stored inside a rough stone recovered from carbon deep beneath the soil. Because these elements are generated organically and are unique to each stone, they are referred to as flaws or inclusions.

Report
GIA
- The Gemological Institute of America (GIA) is regarded as the world's foremost geological research institute. The GIA evaluates and assesses diamonds based on the four Cs: carat weight, cut, color, and clarity.
IGI
-IGI certificates provide a thorough analysis of a gemstone, giving buyers and sellers alike peace of mind.
GCAL
-The unique certificate number assigned to each GCAL certified diamond is laser engraved. Photomicrographs are taken at more than 50x magnification to easily communicate what is inscribed on your diamond and can be used as an additional piece of forensic identification of your diamond.
depth %
depth %
The distance between the culet and the table of a gemstone. The depth percent represents the diamond's height as a proportion of the girdle diameter.
polish
polish
The finish of the diamond's facets is described by this term. The grades for polish include Ideal, Excellent, Very Good, Good, Fair, and Poor. Polish grades of Good or higher have the least impact on the diamond's brilliance and are appropriate for high-end jewelry. Polish is included in an overall cut grade by some gem labs, such as Gemscan.
l/w ratio
l/w ratio
The length-to-width ratio compares a diamond's length to its width to determine how elongated a fancy-shaped diamond appears when viewed from above. Personal choice dictates the length-to-width ratio, with some preferring a more elongated shape and others preferring a more equal or square shape.
Ex. A princess-cut diamond that measures 5.05 mm long by 5.00mm has a length-to-width ratio of 1.01 (5.05/5.00) and will appear perfectly square.
Most popular length-to-width ratios:
- Princess: 1.00-1.05
- Radiant: 1.00-1.05
- Asscher: 1.00-1.05
- Cushion: 1.00-1.05
- Heart: 0.90-1.10
- Emerald: 1.30-1.40
- Oval: 1.30-1.70
- Pear: 1.45-1.75
- Marquise: 1.75-2.30
fluor.
Fluorescence
The response of a diamond to ultraviolet light is described in this definition. There may be some obstruction with the flow of light in diamonds with strong or very strong fluorescence, giving them a milky or slick look.
table %
table %
At the peak of a gemstone, the largest facet is found. The table width defined as the proportion of the girdle diameter is termed as table percent.
Sym.
symmetry
The alignment of the diamond's facets is described by this term. The diamond's facets may be misaligned, resulting in poor light reflection. Ideal / Excellent, Very Good, Good, Fair, or Poor symmetry is rated. Symmetry grades of Good or better have the least impact on the diamond's brilliance and are appropriate for high-end jewelry. Symmetry is factored into the total Cut grade by some gem labs, such as Gemscan.
