Genuine Diamond Right

The purpose of the diamond certificate is to protect consumers from purchasing falsely-claimed diamonds perceived to be a certain value. In todayÂ’s diamond market, itÂ’s easy for retailers to con individuals into buying good quality diamonds. The average person is not armed with the proper facts and skills to distinguish good diamonds from the rest.

An independent Gemological Laboratory issues the diamond certificate. During the evaluation, expert graders examine the jewel. They employ various geological instruments and determine the characteristics of the diamond in the certificate. The various characteristics in the certificate contain which gemological instruments were employed to observe the diamond properties. As such, the diamond evaluation is essential to the pricing because any slight flaw may affect the stoneÂ’s worth.

There are two organizations that are well known diamond certifiers: GIA and the IGI. Both of these organizations are independent laboratories more than qualified to evaluate and certify the diamond. The following is a partial list of the contents of the diamond certificate.

Certificate Number

Each laboratory provides a certificate number. This is the number that certifies the diamonds uniquely. The institution will archive a copy of the certificate so that they can reissue, if itÂ’s lost.

Cut and Shape

There are various shapes such as Heart, Oval, Round and Pear. Additionally, shapes could be in the forms of Brilliant, Emerald, Princess and Marquise.


Proportions of the diamond include depth and table. Depth represents the actual depth of the diamond. The table represents the largest facet of the diamond, sometimes the center piece or main facet. Each of these items is measured by percentages.


The diamond is measured by the millimeter through a measuring instrument. The dimensions are commonly dubbed as “maximum-minimum x depth”.

Carat size

When diamonds are weighed, they are measured by the carat to the thousandth. One carat is roughly 1/142nd once. The word carat originates from a practice of measuring a carob seed in India.

Girdles Found at the Edge of the diamond

The girdle runs between the crown and the diamondÂ’s bottom. The thickness of a girdle is usually described by a range, because it could vary in the thickness.


Clarity is determined by the dimensions of the inclusions and/or irregularities of the item. With the help of an IGI microscope, the grader can examine the qualities of the diamond clarity. Grading of the clarity could have listings such as ‘VVS’, ‘SI’ and ‘I’.


The plot provides data about the uniqueness of the diamond. Like fingerprints, the plot has every characteristic of the diamonds imperfections and physical measurements. With this data, a buyer could verify through the grader (or lab) that the diamond is the right one. The plot is usually plotted in graph format.


The “pointy” facet of the lower of part of the diamond is called a Cutlet. The purpose of the cutlet is to prevent unwanted chipping. Note that some diamonds do not have cutlets.


Under precise lighting, the colors of a diamond can fall under categories of D to Z, D being the highest grade. The colors are determined by comparing the subject diamond with excellent graded diamonds.
