DIAMONDS

DIAMOND IS A SOLID FORM OF THE ELEMENT CARBON WITH ITS ATOMS ARRANGED IN A CRYSTAL STRUCTURE CALLED DIAMOND CUBIC.

The 4Cs of Diamonds

The 4Cs of a diamond are cut, color, clarity, and carat weight.
They define a globally accepted quality of a diamond. Here is a closer look into the 4Cs.

Cut

Cut is a diamond’s symmetry, proportion, and polish. It does not refer to the shape of a diamond. It contributes to how much light a diamond reflects. A well-cut diamond is determined by its brilliance, distribution of light, and scintillation. Brilliance is the light that reflects off of a diamond. Once the light travels through a diamond, it disperses, and the light is separated into flashes of color. The scintillation of a diamond is when the colors flash and are viewable as the diamond is moved around.

Color

A diamond’s natural color, or lack of, indicates a diamond’s grade. The less color, the higher the grade. A diamond’s color measures its rarity, but not quality. The International Color Scale, which was created by the Gemological Institute of America (GIA), is the standard scale used to measure a diamond’s color. This scale ranges from D through Z. D is colorless, usually an icy white, and the rarest and Z has the most color, which is usually a faint yellowish warm shade.

Clarity

Diamond clarity is determined by how pure and clear a diamond is. When a diamond forms, slight flaws are developed on the surface and/or within it. Gemologists use 10x magnification to inspect a diamond for clarity. The lower the number of imperfections, the higher the clarity grade is. However, the imperfections are what makes a diamond unique, and most are not even visible to the human eye.

Carat Weight

Carat (ct.) is the unit of measurement used to weigh diamonds. Although most think that the size of a diamond is what determines carat weight, it is the actual weight of a diamond that determines Carat weight.

Shapes of Diamonds

Diamond shape is the physical appearance and outline of a diamond.
The most popular diamond shapes are as below.

 

Round

Round cut diamonds are the most popular diamonds. Due to its cone shape, the round diamonds are better at the reflection of light, maximizing potential brightness. They are also known as brilliant cut diamonds, meaning they have 58 facets.

 

Princess

Princess cut diamonds are the most popular fancy diamonds. They have pointed corners and are also known as square cut diamonds.

 

Emerald

Emerald cut diamonds have less brilliance than others but are extremely clean, almost ice clear. This diamond is named emerald cut because the shape was originally only used on emeralds. They are also known as step cut diamonds.

 

Asscher

Asscher cut diamonds are very similar to the emerald cut diamonds, but in a square shape unlike the rectangular shape of emerald cut diamonds. They are also known as square emerald cut diamonds and are very clear. The corners are cropped, making the diamond appear as if it is an octagon. These diamonds produce more brilliance than the emerald cut.

 

Marquise

Marquise cut diamonds are shaped like a boat –point tips on top and bottom with a curved middle. The cutting process is similar to the round cut diamonds, but the way the marquise is cut increases the carat weight of the diamond. The reason it is cut like this is to decrease the interior flaws but keep as much as the unblemished part of the diamond as possible.

 

Oval

Oval cut diamonds are elongated round cut diamonds. It is perfect for those who want the characteristics of a round cut diamond but a less round shape.

 

Radiant

Radiant cut diamonds are square or rectangular shape with trimmed corners. It is a mix of the emerald cut shape with the brilliance of the round cut.

 

Pear

Pear cut diamonds are a mix of round cut diamonds with an unusual diamond shape. This allows great brilliance, similar to the round-cut diamond. They are also known as teardrop diamonds.

 

Heart

Heart cut diamonds very distinct shaped diamonds. Symmetry is essential in this cut to ensure the look of a heart. The heart cut diamonds are the most romantic of all the diamond shapes.

 

Cushion

Cushion- cut diamonds have soft, rounded edges to make it less square or rectangular and larger facets to increase brilliance. Because of its shape, the interior flaws can be easier to see. These diamonds are also known as Pillow cut diamonds.

Fancy Colors of Diamonds

Fancy colored diamonds display colors outside of the normal color range. The colors come from different trace elements that are present while a diamond is being formed. Diamonds can come in every color, but colors outside of yellow, brown, gray, or pink diamonds are extremely rare and can be more expensive than a white diamond with the same, or similar, carat weight and quality. The primary and secondary colors determine the tone of a diamond’s color.

The strength of that color is defined by its intensity. The classifications for fancy color diamonds are faint, very light, light, fancy light, fancy, fancy intense, and fancy vivid/fancy deep/fancy dark.

Uncut Diamonds

Uncut diamonds are called rough diamonds. They are mined naturally but they are unpolished and unshaped diamonds, so they vary in sizes. They shine and cost less compared to cut diamonds since they don’t go through high - priced cutting or polishing processes. These diamonds have uniqueness in each piece and no two uncut diamonds are alike.

Uncut diamonds have an eternal and ethereal appeal and jewelry from it enhances the natural beauty of rough diamonds to new heights.
