Diamonds are a derivative of carbon and the strongest element that is known to man. These shining gemstones are scratch proof but are breakable. The attractive nature can sweep one off their feet and not follow proper procedure in acquiring them.
The gemological institute of America, GIA, is the largest gemstone institute in the world that research and certifies precious stones like diamonds. It was founded in 1931, and sole mission is to protect gemstone buyers or sellers in making sure that the standard of gemstones especially diamonds is genuine and authentic by correct certification and approval by the institute.
In purchasing a diamond, there is the need to have it certified. Having a GIA diamond certificate means that the diamond is real and all information about the diamond is duly noted. One sole aim of acquiring this certificate is to ascertain its quality and authenticity. A GIA certificate can be gotten from a certified GIA official from any of their plenty branches around the world. This certificate gives all the necessary information regarding the diamond such as the report number, types of diamond, laser inscription, the diamond dossier, internal structure, grading report of the 4 Cs – color, cut, clarity and carat.
To get all this report, the diamond has to be sent to the GIA for complete analysis. This diamond certificate is the blueprint for a diamond. They go beyond the superficial property of the diamond but deeper into the structure as each diamond is as unique as a fingerprint.
The diamond report number: this is the number of the diamond been analyzed. This number is usually stored in the GIA database and is used as a tracking number in cases of theft, replacement or missing diamonds. The certificate is not gotten for free; an individual who wants a diamond analysis will have to pay a sum for the diamond grading report. The cost depends on the weight of the carat. A one-carat diamond cost $120(one hundred and twenty dollars) for a complete analytical report.
Laser inscription: a laser inscribes diamond is usually done by the GIA after certification, the number is usually inscribed on the underneath part of the diamond piece, and it’s not visible except with a microscope. If you intend to sell the diamond in a secondary market having it will verify that the diamond is real. The laser inscribed number is usually recorded on the certificate and is added proof of the quality of the diamond, though it costs an extra amount; it is very much worth it.
Diamond dossier: is a trademark of the GIA and is a set of standards used in diamond grading and identification. A diamond dossier report is carried out for diamonds that weigh less than 1 carat. The report does not usually contains detail about clarity but contains other information such as
- The shape of the diamond when viewed from above
- The measurement which is the diamond dimensions
- Cutting style of the diamond
- The weight of the diamond
- The color when viewed under light
- The clarity when view 10X under a microscope for blemishes
- The finishing
There are other results tested that appear in a diamond dossier, but the 4Cs are the set standard for diamond analysis.
The 4Cs stand for the cut, the clarity, the color and the carat of the diamond.
Clarity: a diamond is naturally made up of a crystalline internal structure. This crystallization process takes place during the formation of the stone in the earth. The clarity of a piece of diamond rock refers to as the amount of crystallization in any particular stone. A low-level crystallization makes the rock more valuable and of higher quality.
Color: white diamonds have greater value because of the amount of yellow hue produced when they dispel light. The color chart is by the standard set by GIA.
Carat: this is the unit of weight of the measured stone. A diamond is measured by accurate scales where one carat is equal to 0.2 grams. A carat is equal to 100 points as registered by the GIA.
The cut: diamonds come in different geometrical shape. The cut is referred to how many faces are visible. The cut is affected by the way the stone is refined; a brilliant polish produces a finer finish and beauty with its faces visible unlike a dull gem got from an inferior polish. Depending on their polish, we have 4 kinds of cuts:
Brilliant polish is a round shape diamond with 57 planes with exceptional beauty. It has a shape like a cone and a sparkle that makes this type of diamond a rare find.
Radiant diamond is an 8 face diamond usually round and a shine that is alluring when properly polished
The round diamond is unique because when looked at closely; it looks like four prongs are holding the diamond in place
The princess cut is a rectangular shape diamond which looks like an inverted pyramid with four slanting sides.
All these are what a grader looks for when a diamond is sent to the gemologist for analysis. The report is very important as it certifies the authentic nature of the diamond. Do not go for diamond appraisals as it does not give detail information about the diamond but a face value of what the diamond might is worth in the market. If you are not sure about a diamond, please purchase from verifiable sellers to ensure quality diamond to avoid buying diamond look alike or gemstones that have same physical property as diamond. Get a GIA certificate for your diamond and enjoy that stone in peace.
