A diamond is a grain of sparkling brilliance meant to last for all eternity. No two diamonds are the same and this adds to the uniqueness of the diamond. Before the 20th century, there was no standard to measure the value of a diamond. The first and now globally accepted benchmark for evaluating diamond quality and value is the 4C's methodology, devised by GIA’s Richard T. Liddicoat in 1953.


Diamonds come in a variety of colours, with varying degrees of associated value and worth. A pure white diamond is like a drop of pure water, bereft of any hue. The traditional rule here is simple - the lesser the body colour in a stone, the more intense its ability to reflect, and therefore, greater the value. The GIA D-to-Z colour grading scale begins with D representing colourless and moves up to Z. The system tracks the degree of colourlessness by comparing a stone under controlled lighting.


Almost all diamonds contain small imperfections called blemishes. Clarity refers to the degree to which these imperfections are present. Measuring diamond clarity involves determining the number, relief, size, nature, and position. A flawless diamond is often a rarity, and thus highly treasured. As per GIA Diamond Clarity Scale, there are 6 categories, some of which are divided, for a total of 11 specific grades : (VVS1 and VVS2), (VS1 and VS2), (SL1 and SL2), (L1, L2, and L3)


The cut of a diamond is the most important component of the four C’s, as a good cut gives a diamond a radiance that emanates from its very core. Diamonds are renowned for their ability to transmit light and sparkle intensely. We often think of a diamond's cut as its shape (round, emerald, pear), but a diamond's cut grade is really about how well a diamond's facets interact with light. GIA helps in calculating the exact proportions of these facets and has created a value chart of how a diamond interacts with light: Brightness: Internal/external white light reflections Fire: White light scattering into VIBGYOR (rainbow hues) Scintillation: Sparkle indicators for a diamond and reflection pattern created.


A carat is a unit of measurement used to weigh a diamond. One carat can be divided into a '100' points – allowing precision measurements to the 100th decimal place.
