Diamond Grading and 4C's

In the pursuit of absolute perfection, Happy crafts diamonds with clarity and flamboyant brilliance. We are constantly innovating and developing our crafting technology to offer you brilliance you've never seen before.

Cut

Cuts are mainly the arrangement of facets in the stone, affecting the cost and beauty of a diamond. To what extend a diamond will reflect light from within depends on the skill and craft of the diamond cutter. When a diamond is cut with precision, light gets reflected from one facet to another and results in a burst of brilliance.

EXCELLENT

The diamond, which has an even pattern of bright and dark areas, scores in the top category for all grade-setting determinants.

Clarity

Diamonds receive the FL (flawless) grade when there is no discernible inclusion or blemish that causes interference with the passage of light through the stone. At Happy, we offer diamonds that achieve a grade of VS2 and above. VVS and VS graded diamonds are expensive whereas SI1 and SI2 graded diamonds are more affordable.

A grading system has been established by the GIA (Gemological Institute of America) for measuring the type and size of these impurities.

IF

INTERNALLY FLAWLESS

No inclusions and only blemishes are visible to a skilled grader using 10x magnification.

Color

More light passes through diamonds that display little color, creating a prism-like effect. If a stone is totally transparent, it is considered rare; however, notable exceptions are fancy colored diamonds such as yellow, green, blue and pink. Grades are allocated to a diamond according to the level of color it possesses.


Based on the color scale established by the GIA (Gemological Institute of America) a letter is assigned to the degree of colorlessness found in diamonds.
Starting from D and ending with Z, each letter in descending order denotes an increasing amount of light (yellow, brown or grey) in the diamond.

Carat Weight

Carat determines the weight of a diamond with 1 carat being equivalent to 200 milligrams or 0.2 grams. One carat is also divided into 100 points. These points are used for describing increments of weight within a carat. A diamond's price per carat increases in proportion with the size of the stone. Two diamonds of the same weight can have different values based on their color, cut and clarity.

Diamond Symmetry Grade Recommendations

Diamonds that have a good grading in other parameters would essentially have a symmetry grade of Excellent, Very Good or Good. It is important to have Excellent, Very Good or Good symmetry in diamonds of VVS2 Clarity and higher, since the subtle defects highlighted by Fair or Poor symmetry would compromise the diamond's otherwise flawless appearance. Diamonds with Poor symmetry have defects visible to the naked eye and hence should be avoided in all cases.

What Is Diamond Symmetry?

Symmetry refers to the alignment of the facets of a diamond. A diamond's symmetry grade is determined by the presence and visibility of symmetry deviations at 10x magnification. An ideal symmetry is achieved when the top of a diamond (crown) is in perfect alignment with the diamond's bottom (pavilion) where they meet at the girdle. When cutting the facets of a diamond, the goal of a cutter is to get maximum value out of the rough stone. Hence, cutting is a carefully planned activity.

Diamond Polish Grade Recommendations

Diamonds having a polish grade of Excellent, Very Good and Good are all optimum, as any polishing flaws would not be visible to the naked eye. The miniscule flaws in these polish grades do not have an impact on the diamond's overall appearance. For diamonds with clarity grades of I1 or lower, a polish grade of Fair is acceptable since these diamonds already possess internal inclusions that are visible to the naked eye, rendering any polish markings less relevant.

Polish Marks On A Diamond

Polish is the extent of smoothness and Polish marks are superficial and do not penetrate the diamond's surface. They are hence graded separately and not as clarity attributes. Common polish marks are: Scratch – Transparent looking white line on the diamond's surface. Nick – Minute notches found on facet or girdle junctions. Abrasion – Series of nicks at facet junctions. Pit – A small opening caused by inclusions falling out during polishing. Skin bumps – Bumpy, uneven texture on the diamond's surface. Polish lines – Parallel fine lines that may appear white or translucent. Rough girdle – An unpolished girdle left in its original state.

Diamond Polish & Symmetry

Polish is the extent of smoothness and diamond's surface after it has been cut and given its facets. A well polished diamond has the ability to transmit light without any distortions and produce crisp reflections, whereas a poorly polished diamond can look dull. While the diamond cutter aims to achieve a finish, a gemologist determines the diamond's polish grade by looking at under 10x magnification for any imperfections that may have resulted from the cutter's work. While the blemishes are usually microscopic and cannot be spotted by the naked eye, at times they can noticeably affect the visual appearance of the diamond.
