4. 4Cs : The 4Cs of a diamond

a. CUT

A good cut gives a diamond optical efficiency – the way it handles light for maximum brilliance, fire and scintillation. A gemologist evaluates a diamond’s cut base on its girdle, table size, crown angle, pavilion depth, and culet size. The details of the cut are made up of Polish and Symmetry. All Cut, Polish and Symmetry should be graded under the following 5 levels. A diamond with “triple excellent” is believed to emit maximum light returns.

b. COLOUR

Diamonds that range from colorless to light yellow/light brown are graded under the D-to-Z range. A gemologist values color based on how noticeable the color is, using naked eye, by comparison against the master set stones. All other value factors being equal, colorless diamonds are the most valuable and desirable because of their rarity.

c. CLARITY

A diamond’s clarity refers to the freedom from the presence of characteristics on and within the stone. Blemishes are confined to the surface, while inclusions are typically enclosed within a diamond (or extend from the surface into the diamond). The factors that determine the effect of characteristics on a clarity grades are size, number, position, nature and relief. The grades to describe the clarity are

d. CARAT

The carat represents the weight of a diamond. One metric carat equals to 0.2grams. Therefore a 1 carat diamond might have diameter that ranges from 6mm to 6.6mm. The magic sizes, which are popular, are probably 0.30ct, 0.50ct, 0.70ct, 1ct, 1.2ct, 1.5ct, 2ct and so on. All the 4Cs play important roles in determining the value of a diamond.

7. Reports

a. GIA

The Gemological Institute of America (GIA) was established in 1931 as a non-profit institute and is known to be the world’s most recognised and trusted grading lab, with its reports representing an independent third-party opinion in diamond grading. In the 1950s, GIA created the 4Cs of diamond quality, including the D-Z colour scale and flawless–I3 clarity scale of a diamond. A GIA report also provides a poor to excellent grade for cut, polish and symmetry as well as a proportion diagram of a diamond. Most of eClarity’s diamonds are GIA-certified.

b. AGSL

The American Gem Society Laboratories (AGSL) was established in 1934 by a group of independent jewellers and Robert M. Shipley, the founder of the Gemological Institute of America (GIA). It is the first lab to offer numerical cut grading for diamonds including fancy-shaped diamonds such as princess, oval and emerald cut. AGS has 11 Cut Grades (0-10). A “0” grade is representative of the most desirable Ideal Cut and a “10” represents a poor cut. AGS grades seven aspects of the cut of each diamond. These include the table diameter, crown angle, pavilion depth, girdle thickness, culet size, polish and symmetry. The first five of these are grouped under the term “Proportion”. Diamonds that score 0 in all three cut categories are premium cut diamonds emitting maximum light returns.

c. EGL

The European Gemological Laboratory (EGL) was founded in 1974 in Belgium and is popular for its lower cost and fast service. EGL introduced the SI3 grade as a clarity grade. It has a clarity scale of flawless, internally flawless, very, very slightly included 1 – 2, very slightly included 1 -2, slightly included 1 – 3, and piques 1 – 3. EGL also offers a wide range of certificates, including the full certificate, mini certificate and the Certicard TM. The full certificate includes information on the 4Cs of the diamond, proportions and polish, as well as an image of the laser inscription on the girdle of the diamond. The mini certificate includes all information found in a full certificate, but in a compact format. The credit-card sized Certicard TM also includes all information as in a full certificate, together with a digital picture of the diamond face-up and the laser inscription on the girdle of the diamond.

d. IGI

The International Gemological Institute (IGI) is the world’s largest independent gemological institute with its headquarters in Antwerp, Belgium, founded in 1975. It is also popular for its lower cost and fast service. It has a D to V colour grading and an IF to I3 clarity grading and provides quantitative information on the proportions of a diamond.

e. HRD Antwerp

Hoge Raad voor Diamant (HRD) or Diamond High Council is a diamond institution based in Antwerp, Belgium. The Diamond Lab of HRD Antwerp was founded in 1976 to meet the growing demand for reliable grading of diamonds. Its reports are mainly found in Europe and Asia. It has a colour grading of exceptional white+ to tinted colour (yellowish). Its cut grade system includes the proportions and finish grade of the diamond: proportions has a grading scale from very good (most ideal) to unusual, while finish grade has a grading system of very good (most ideal) to poor. The report also includes the detailed proportions of the diamond.

a. Getting the right ring size

A printable ring sizer-cum-ring size guide is available. Kindly note that sizes on the printable  guide are in Asian sizes. Refer to below for the size conversion chart.

Before you print, please be sure to set the page scaling to ‘None’ on the print dialogue box.

b. Guidelines

1. For a higher ring size accuracy, measure the finger at the end of the day when the fingers are at their largest.

2. It is not advisable to measure cold fingers. This is when they are at their smallest.

3. Use a ruler to reconfirm the printed measurements to ensure correct scale.
