Grading System

Fancy Shape

Brillant Round

Round Cut Diamonds are one of the most popular while the classic shape represents eternal love. This circular shape shows the 58 auxiliary eye-catching facets of the diamond. It maximizes and captures the light from all angles, which is why it is popularly guided to as a round brilliant diamond.

Oval

An oval cut diamond is a type of diamond cut, with a symmetrical, elongated, and rounded shape. With their larger surface area, oval diamonds optimize carat weight – meaning they often look larger than a round diamond of the same carat weight.

Marquise

The marquise is a variant of round and pear shaped diamonds and, like the oval, is a perfect complement to long, slender fingers. But, as we mentioned, it can also create this effect thanks to its shape. The long-thin body and pointed ends draws the eye up, so your fingers will look longer and thinner when you're sporting this stone in your engagement ring.

Pear

The pear diamond—also known as the teardrop or pendeloque cut—is unlike any other diamond cut. It’s called a modified brilliant cut, one that blends the Marquise and oval cuts with one rounded end and a point on the other. Its signature silhouette is instantly recognised and much beloved.

Heart

Heart a fancy cut and contains 56-58 facets that capture and reflect light, resulting in visible brilliance. The wings of the heart should be symmetrical, with a graceful curve that provides excellent fire, ending in a neat apex point.

Princess

A princess cut diamond is traditionally a square diamond that offers excellent fire and brilliance. This fancy shape diamond is designed from the inverted pyramid of the rough diamond stone. Princess cuts, like this gorgeous 0.81ct I color, are among the most brilliant of all diamond shapes and are a popular choice for engagement rings. The highest quality princess cuts are those with a distinct square shape with a length to width ratio of 1.00 – 1.05.

Asscher

Asscher cut is the name given to a particular square, step cut diamond. Unlike the square shape princess cut diamond, Asscher diamonds feature large step cut facets, producing optical properties that appear like a ‘hall of mirrors’. With it’s signature clipped corners, Asscher diamonds are sometimes referred to as octagonal, or square emerald cuts.

Emerald

The emerald cut diamond flaunts an elongated, rectangular shape and chiseled step cuts, with straight linear facets—usually arranged parallelly down the stone. To add stability and prevent fractures, the corners of an emerald cut diamond are usually cropped.

Radiant

The radiant cut diamond owes its brilliance to the 70 facets found its pavilion and crown. The precision of each facet offers immense brilliance and fire. The radiant cut’s brilliance is surpassed only by the round brilliant cut.

Cushion

The cushion cut diamond once referred to as old mine cut) combines a square cut with rounded corners, much like a pillow (hence the name). This classic cut has been around for almost 200 years, and for the first century of its existence was the most popular diamond shape (similar to round cut today). Until the early 20th century, the cushion cut diamond was the de facto diamond shape

Fancy Color
fancy-shape

In diamonds, rarity equals value. With diamonds in the normal range, value is based on the absence of color, because colorless diamonds are the rarest. With fancy color diamonds—the ones outside the normal color range—the rarest and most valuable colors are saturated pinks, blues, and greens. In all cases, even very slight color differences can have a big impact on value. Compared to fancy yellows and browns, diamonds with a noticeable hint of any other hue are considerably more rare.

Even in light tones and weak saturation, as long as they show color in the face-up position, they qualify as fancy colors. Red, green, and blue diamonds with medium to dark tones and moderate saturations are extremely rare. Grading fancy color diamonds is complex and specialized, and it takes highly trained laboratory graders to complete the process accurately.

Hearts And Arrows
Lab-Grown

Hearts and Arrows Diamonds are the most beautiful diamonds in the world. The secret to their beauty is revealed here!

The hearts and arrows pattern (often marketed under brand names such as 'Hearts on Fire') refers to a symmetrical light pattern visible using a specialized viewer in diamonds cut within certain narrow specifications.

History of Visible and Arrows

Hearts and Arrows Viewer Modern, portable H&A viewers The hearts and arrows pattern was first viewed using a Firescope; a tool developed by Kazumi Okuda in the 1970s. Firescopes and their modern equivalents (such as the H&A Viewer, Ideal-scope and ASET-scope) use colored reflectors to display a pattern showing the direction and intensity of light emitted from a diamond. These colorful patterns can be evaluated to determine how much light is exiting the diamond at proper angles, and whether the diamond is optically symmetrical (indicated by a uniform pattern).

In the example at left, red represents light being emitted from the diamond in a direction and intensity that will be perceived by the viewer as brightness. Pink areas represent areas of less brightness. Dark areas indicate areas where light is blocked by the viewers head (these areas are perceived as dark flashes, or scintillation, when the viewer or the diamond moves). Finally, white areas indicate where light is traveling through the diamond, and 'leaking' out of the bottom (perceived as dull or dark areas in the diamond). Different types of viewers will use different color schemes, but all produce similar patterns.

The 4C's of the Diamonds

CUT

Used to define the shape and proportions of a diamond, the cut is an influential factor on the diamond's fire,sparkle and brilliance.

COLOR

The color ratings of diamonds are actually based on the absence of color.Ratings range from D (colorless) to Z(yellow), The less color the higher the grade.

CLARITY

Difficult to see with the naked eye, clarity is the degree to which a diamond is free from inclusions. Each diamonds receives a clarity grade on a scale of flawless to 13.

CARAT

People often mistake carats as a measurement of size, but they actually measure weight. Two diamonds of equal weight can have unequal value depending upon the cut, color, and clarity of each.

The Grading Process

The first stage in diamond grading is weighing the diamond. Carat weight is the standard weight unit for gemstones. Diamond grading scales are calibrated to four decimal places to ensure accuracy. Carat weight is reported to two decimal places.Diamond color is graded in a standardized viewing environment. IGI gemologists analyze color in the D to Z color range with the diamond placed upside down, viewed through the side, to facilitate a neutral view. Grading color from the top is not practical because of three factors which may influence color appearance in normal viewing.
IGI grades clarity according to internationally accepted standards at 10X magnification, according to the visibility, size, number, location and nature of internal and surface characteristics at that magnification. Diamonds with characteristics which are immediately obvious or noticeable are likely candidates for the lower grades, whereas diamonds with characteristics which are minor, minute or extremely difficult upon initial analysis at that magnification may qualify for the higher grades.
Fancy Shape Cut Grading: Diamonds are assessed using a four-step system combining polish and symmetry assessment with proportions qualifications, shape-specific requirements and light return grading. In the areas of color and clarity analysis multiple gemologists take the diamond through the grading steps and provide opinions, completely independent from the others. Color and clarity grades are only finalized when a consensus is reached. Between each grading step, a diamond returns to central control, ensuring that its distribution to various gemologists is completely random.
Diamond grading reports are printed on advanced security paper with no less than five security features. These include tear proof paper, micro printing, holographics and other security features. The diamond is weighed, verified as matching the report by central control, cleaned and prepared for return to its owner along with the new diamond grading report, which is placed in a protective sleeve or binder.
