JEWELRY & DIAMOND EDUCATION


Diamonds can be a very frustrating purchase. With no two diamonds being perfectly alike, the choices are endless and the options are overwhelming. However, even with some basic knowledge about diamonds, you can be sure to make the right purchase.

Diamonds are graded by many different laboratories (such as the Gemological Institute of America (GIA) or the European Gemological Laboratory (EGL), and others). The 4 most important factors when considering a diamond is what is referred to as the 4 Cs (Carat, Color, Clarity, and Cut). It is important to note that different laboratories have different standards when grading diamonds. GIA is considered to be the strictest of all the laboratories, but all diamonds sold by Brilacci are graded by the most respected laboratories in the world.

All diamonds listed on our website have been handpicked by certified gemologists. To make your job easier, we only list diamonds which meet our extremely strict standards. Diamonds which we believe are not visually appealing will never be sold on our website

DIAMOND CARAT

A diamonds carat is the most visually apparent factor when comparing diamonds. Although many think of carat as a unit of size, a diamonds carat weight is actually its weight. A diamonds carat weight is one of the most important factors in the evaluation of its price.

DIAMOND CARAT

A diamonds color is the second most visually apparent factor; it measures the natural color, or lack of color, visible within the stone. The less color a diamond exhibits, the higher the rarity, and therefore the higher the value.

D - Completely colorless. The highest color grade, extremely rare, and most valuable.

E - Completely colorless. Only extremely minor traces of color can be detected by an expert gemologist under 10x magnification in a controlled environment. Completely colorless to the human eye. These diamonds are very rare and extremely valuable.

F - Colorless. Only very slight traces of color can be detected under 10x magnification by expert gemologists. Still considered colorless. These diamonds are rare and extremely valuable.

G - Colorless. Color may be slightly noticeable under 10x magnification when compared to diamonds of better grades. This color grade is still rare and very valuable. G colors offer a great value.

H and I - Near Colorless. Color is more noticeable under 10x magnification when compared to diamonds of better grades. This color grade is rare and valuable. H and I graded diamonds offer good value.

J - Noticeable color. Color is noticeable when compared to diamonds of better grades. J color diamonds are the lowest graded diamonds offered by Brilacci. We do not recommend any diamond with a lesser grade than J.

DIAMOND CLARITY

A diamonds clarity is the third most visually apparent factor. Clarity measures the natural inclusions and blemishes on and within a diamond. A diamond with a higher clarity is much more rare than a diamond with a lesser clarity, and therefore much more valuable.

FL - Flawless. Diamonds with this clarity grade have no internal or external flaws. These diamonds are extremely rare, and extremely valuable.

IF - Internally flawless. Diamonds with this clarity grade have no internal flaws. These diamonds are also extremely rare, and extremely valuable.

VVS1 - Very Very Slightly Included 1. Diamonds with this clarity grade have inclusions that are extremely difficult to see under 10x magnification (invisible to the human eye).

VVS2 - Very Very Slightly Included 2. Diamonds with this clarity grade also have inclusions that are very difficult to see under 10x magnification (invisible to the human eye). Slightly more included than VVS1

VS1 - Very Slightly Included 1. Diamonds with this clarity grade have inclusions that are difficult to see under 10x magnification. Typically inclusions are practically invisible to the naked eye.

VS2 - Very Slightly Included 2. Diamonds with this clarity grade have inclusions that are difficult to see under 10x magnifications. Typically inclusions are more or less invisible to the naked eye. Slightly more included than VS1.

SI1 - Slightly Included 1. Inclusions are visible under 10x magnification, and may be very slightly visible to the naked eye.

SI2 - Slightly Included 2. Inclusions are visible under 10x magnification, and may be slightly visible to the naked eye. Slightly more included than SI1.

I1 through I3 - Inclusions are visible to the unaided eye. Generally considered unattractive and are not sold by Brilacci.

DIAMOND CUT

A diamonds cut determines how well it will reflect and refract light. Diamonds with a better cut are more balanced in their proportions and therefore have a greater brilliance.

IDEAL - Diamonds with this grade are cut to the highest standards. These diamonds have the best possible facet patterns, the most desirable girdle and culet dimensions, and are proportioned to return the maximum possible sparkle.

EXCELLENT - These diamonds are cut with extremely high standards. These diamonds reflect nearly all light that enters the diamond. Top 3% of diamonds fall under this criteria.

VERY GOOD - Superior quality that reflects nearly as much light as the excellent cut, but at a substantially lower cost. Top 15% of diamonds fall under this criteria.

GOOD - Premium quality cut to optimize size without sacrificing quality. Reflects most light that enters. Top 25% of diamonds fall under this criteria.

FAIR - Adequate quality cut which reflects some light while maximizing weight. While now as sparkly as the good cut, it is still a sought after diamond. Top 35% of diamonds fall under this criteria.

POOR - Inadequate quality that reflects only minimal amounts of light. Not sold by Brilacci as it does not meet our standards.
