Diamond Info
Our expert gemologists, equipped with specialized tools, carefully evaluate the weight, dimensions, and quality features—cut, color, clarity, and carat—of each diamond. A certified diamond report from independent gemology labs, such as GIA and IGI, offers a professional assessment of the diamond's quality. Trust in our diamonds, certified by the world's foremost gem grading authorities.
Just like fingerprints, every diamond is one-of-a-kind. Skilled cutters work to bring out each stone's unique features, enhancing its beauty. We use a set of standards known as the 4 Cs – cut, color, clarity, and carat – to rate and ensure the quality of each gem.
The cut, color rating, clarity grade, and carat weight can help determine diamond quality, but there's no "right answer" to how a diamond should look. Giuliana Jewels is dedicated to providing you with your ideal diamond, specific to your requests and preferences.
The 4 Cs
Cut
Cut is often considered most important among the four C's, influencing a diamond's sparkle and brilliance. The cut of the diamond not only refers to the diamond’s shape but it's balance in proportion, symmetry, and polish created by the cutter, not the diamond's shape. A well-cut diamond can seem larger and enhance both color and clarity. Each rough diamond is carefully examined and mapped to maximize size and improve clarity through cutting. The technique highlights the unique characteristics, intensifying its distinctive beauty. An ideal cut, neither too shallow nor too deep, optimizes light performance, allowing the diamond to radiate more shine. Too shallow loses light from the bottom, and too deep lets light escape from the sides.
Color
Most gem-quality white diamonds are graded based on the absence of color. A chemically pure and structurally perfect diamond has no hue, making it more valuable. GIA's color-grading system, from 'D-to-Z,' measures the degree of colorlessness. Though subtle, these distinctions significantly impact a diamond's overall quality and light reflection. Diamonds with less color permit more light to pass, resulting in increased brilliance.
Clarity
A diamond's distinctiveness lies in its natural features, determined by its clarity. Clarity involves grading the presence of inclusions (internal) and blemishes (surface). Diamonds form from carbon under intense heat and pressure, resulting in various characteristics called inclusions and blemishes. Clarity, assessed on a scale from I3 to FL, considers the number and types of these features. Using 10X magnification, graders create "diamond plots" to map and identify each stone's unique internal pattern—akin to a fingerprint. Inclusions' quantity, size, color, location, orientation, and visibility impact the final clarity grade. While flawless diamonds are rare, clearer stones emit more brilliance
Carat Weight
Diamond carat weight, a unique gemstone measurement, indicates the diamond's mass, equivalent to .2 grams or .007 ounces. Unlike the gold-related 'karat,' carat weight determines visual size, yet a higher carat weight doesn't guarantee a visually larger appearance. Larger diamonds command higher prices due to their rarity, with fewer than one in a million mined rough stones producing a finished 1-carat diamond. Each diamond possesses its own DNA, akin to human fingerprints, highlighting its individuality. Beauty doesn't demand perfection, and these distinctive qualities contribute to the diamond's allure
