Experts grade the cut of a diamond on a scale ranging from 'Excellent' to 'Poor'.

2. Color: From Dazzling White to Fancy Colours Diamonds

Diamonds come in a variety of colors, ranging from colorless to fancy-colored gems. 

A diamond's color ranges from subtle yellow to brown tints, indicating the presence or absence of color.

Colour 4 C’s of diamonds

A diamond color is graded on a scale from D (colorless) to Z (light yellow or brown) by The Gemological Institute of America (GIA)

Colorless or near colorless diamonds, prized for reflecting white light, are typically the most valuable due to maximum light transmission. Diamonds having a yellow or brown tint are considered less valuable.

Fancy colored diamonds, like pink, blue, or yellow, offer exceptional rarity and value with their unique and vibrant appeal.

3. Clarity: The Diamond's Inner Perfection

The clarity of a diamond refers to the presence of blemishes and inclusions within the stone. Internal flaws are referred to as Inclusions, while blemishes are external flaws. 

These imperfections, however, are formed during the diamond's natural crystallization process.

The Gemological Institute of America (GIA) grades diamonds on a clarity scale, ranging from Flawless (no inclusions or blemishes visible under 10x magnification) to Included (inclusions visible to the naked eye).

Flawless diamonds are highly prized, many diamonds with slightly lower clarity grades appear flawless to the naked eye and offer excellent value for money.

While choosing your Dream Diamond choosing one with a clarity grade of SI1 or higher will appear eye-clean, meaning that inclusions will not be visible to the naked eye. A diamond with excellent clarity will have fewer imperfections, allowing for maximum light reflection and brilliance.

4. Carat Weight: The Diamond's Size and Rarity

The carat weight is perhaps the most popular of the 4 C’s of a diamond. The carat weight of a diamond refers to its weight, not its size.

A carat is equal to 200 milligrams, and each carat can be divided into 100 points. 

The price of a diamond increases substantially with its carat weight. Additionally, larger diamonds are generally more rare and command a higher price per carat. However, it's important to note that the carat weight may influence a diamond's size, but it does not solely determine its value.
