Diamond Education & Grading, Laxmi Diamond
Laxmi Diamond Grading System

Every loose diamond sold by us has been analyzed and graded by authentic ,renowned and respected international laboratories like GIA or IGI or HRD etc and / or by our in-house team of professionally trained gemologist.

Before our customers purchase a diamond, they should expect to review a copy of its certification as proof that it has undergone an unbiased, professional examination.

A diamond certification is a report created by a team of gemologists. The diamond is evaluated, measured, and scrutinized using advanced industry tools. A completed certificate includes an analysis of the diamond’s dimensions, cut , clarity, color, polish, symmetry, and other characteristics.

Laxmi Diamond Awareness program is aimed at educating about different aspects of following evaluated criteria of Diamonds viz.

SHAPE

Since all diamond shapes are very different, unique characteristics determine quality for each shape.

Following are the commonly known shapes of Diamonds.

Clarity

Clarity is a measure of the number and size of the tiny imperfections that occur in almost all diamonds.

Many of these imperfections are microscopic, and do not affect a diamond's beauty in any discernible way.

Clarity simply refers to the tiny, natural imperfections that occur in all but the finest diamonds. Gemologists refer to these imperfections by a variety of technical names, including blemishes and inclusions, among others.

Diamonds with the least and smallest imperfections receive the highest clarity grades. Because these imperfections tend to be microscopic, they do not generally affect a diamond's beauty in any discernible way.

"eye-clean" diamond is the one that has no imperfections visible to the unaided-eye through the facu-up.

FL,IF Flawless, Internally Flawless: No internal or external imperfections. Internally Flawless: No internal imperfections. Very rare.
VVS1,VVS2 Very, Very Slightly Included: Very difficult to see imperfections under 10x magnification. An excellent quality diamond.
VS1,VS2 Very Slightly Included: Imperfections are not typically visible to the unaided eye. Less expensive than the VVS1 or VVS2 grades.
SI1,SI2 Slightly Included: Imperfections are visible under 10x magnification, and may be visible with the unaided eye.
I1 Included: This grade of diamonds will have minor inclusions that may be visible to the unaided eye.
I2,I3 Inclusions are heavy and visible to the unaided eye.

CUT

Cut is a diamond's most important characteristic. It has the greatest overall influence on a diamond's beauty. It determines what we generally think of as sparkle.

A diamond's cut grade is an objective measure of a diamond's light performance, or, what we generally think of as sparkle. When a diamond is cut with the proper proportions, light is reflected back to the top of the diamond. If it is cut too shallow, light leaks out of the bottom; too deep and it escapes out of the side.

EX Excellent: Reflects nearly all light that enters the diamond. An exquisite and rare cut. All the dimensions are perfectly maintained in the described mathematical proportions in order to get the most sparkle.
VG Very good cut: Reflects almost the same light as an Excellent cut, with slightly broader proportions.
GD Good cut: Reflects most light that enters. In this case , cutter might have chosen to get bigger size to make it more economical.
FR Fair cut: Reflects lower proportion of light due to weaker proportion that cutter has chosen to get maximum size or yield . These cuts are heavily discounted in price.

CARAT

Carat is specifically a measure of a diamond's weight A one-carat diamond is comprised of 100 points called cents . Hence, 50 cents is equal to 1/2-carat, and so on.

Most of the time ,value of the diamond increases with increase in Carat size.

COLOR

Grading Color

Color refers to a diamond's lack of color, grading the whiteness of a diamond.

A color grade of D is the highest possible, while Z is the lowest.

A diamond's color grade is based on its lack of color. The less color a diamond has, the higher its color grade. After cut, color is generally considered the second most important characteristic when selecting a diamond. This is because the human eye tends to detect a diamond's sparkle first, and color second. Diamonds graded J or better are colorless or near-colorless.

D Absolutely colorless. The highest color grade. Extremely rare.
E,F Colorless. Minute traces of color can be detected by an expert gemologist.
G,H Near-colorless. Color difficult to detect unless compared side-by-side against diamonds of better grades.
I,J Near-colorless. An exceptional value with slightly detectable warmth or tone.
K,L,M Noticeable color.
N to Z Easily Noticeable color.
