Diamond Certificate

From AKARA Fine Jewelry’s Diamond Specialist

Before purchasing a diamond, you should expect to review a copy of its certificate as proof that it has undergone an unbiased, professional examination. A diamond certificate, also called a diamond grading report, diamond dossier®, or diamond quality document, is a report created by a team of gemologists. The diamond is evaluated, measured, and scrutinized by trained eyes, a jeweler’s loupe, a microscope, and other industry tools. A complete certificate includes an analysis of the diamond’s dimensions, clarity, color, polish, symmetry, and other characteristics. Many round diamonds will also include a cut grade in its certificate.

All AKARA Fine Jewelry have been analyzed and graded by either the Gemological Institute of America (GIA) or the Hoge Raad voor Diamant (HRD). These two laboratories are among the most respected laboratories in the diamond industry, and are known for their consistency and unbiased diamond grading systems. Diamonds that are accompanied by these grading reports are the most highly valued in the industry.


Understanding a diamond’s qualities is straightforward and simple.


A diamond’s weight is measured in carats, which is a small unit of measurement equal to 200 milligrams. AKARA Fine Jewelry offers diamonds in every size. We have one of the widest selection ranges of diamonds in Thailand. Our customers are welcomed to choose the diamond size that most suit your preference and budget.


The diamond cut is the most important element to consider when buying a diamond. The cut is the biggest factor in creating sparkle and fire, and without a high cut grade even a diamond of high quality can appear dull and lifeless. A diamond cut poorly and too deep can face-up smaller than it actually is. Use our buying tips, diamond cut grading scale and comparison chart, and expert tips to help you choose the best diamond cut for your budget.

Diamond shape is the geometric appearance of the diamond. Round is by far the most popular shape. Other diamond shapes are presented per below.


Color refers to the natural body color of a diamond and not to the reflection of spectral colors that flash when a diamond moves. Most diamonds naturally exhibit slight hints of yellow, brown, or gray. This color is caused by natural trace elements of nitrogen that were present when the diamond formed under the Earth’s crust. The less color a diamond exhibits, the higher the rarity, and therefore the higher the value.

Diamonds with less color allow more light to pass, releasing more brilliance and fire. A diamond acts as a prism by dividing light into a spectrum of colors and reflecting this light as colorful flashes called dispersion or fire. Similar to looking through colored glass, color in a diamond will diminish the spectrum of color, or fire, emitted by acting as a filter. A diamond with a higher color grade, i.e., one with less color, demonstrates more colorful fire.

If you are budget conscious, you can get a fantastic diamond value by choosing a G-J color diamond. Most often you will notice little or no color with the naked eye.



It is the visibility, number and size of these inclusions that determine the diamond’s clarity grade. The better the clarity of a diamond is, the greater the brilliance and it also increases the value or price of the diamond. Diamond clarity is measured on a scale from Flawless (FL) or Internally Flawless (IF) to Included (I1, I2, and I3). Each of these characteristics are plotted on a diamond diagram that is included on the diamond’s grading certificate.

Most people seem to think they need to purchase a diamond with a clarity grading no lower than VS2, however, we believe you can go as low as I1 depending on the diamond’s shape and where the inclusions are located. The jump in price from an SI2 to VVS1 clarity is significant but with an SI, you could still have an “eye clean” diamond on your hands without the high price tag.
