Diamond Education

Formation: A Testament to Time and Pressure


Diamonds, revered for millennia, stand unrivalled in the mineral kingdom due to their unique chemical composition and crystal structure. They crystallise under extraordinarily high temperature and pressure conditions, occurring only within a narrow range of depths—approximately 150 kilometres beneath the Earth's surface. This extreme environment facilitates the formation of diamond's isometric crystal structure, where carbon atoms bond uniformly in all directions, resulting in the gem's unparalleled hardness and brilliant optical properties.


The Four Pillars of Diamond Quality


Gemologists and connoisseurs evaluate diamonds based on four fundamental characteristics, colloquially known as the "Four Cs." These criteria not only determine a diamond's beauty but also its value and rarity. Understanding these characteristics empowers consumers to make informed decisions about their investment.


  1. Clarity: The Inner Landscape


Clarity grades assess the presence and visual impact of internal characteristics (inclusions) and external imperfections (blemishes).


Grading Scale: Ranges from Flawless (no inclusions or blemishes visible under 10x magnification) to Included (inclusions observable to the naked eye).

Higher clarity grades typically correlate with increased rarity and value.


  1. Colour: The Spectrum of Brilliance


In most diamonds, the ideal is the absence of colour, allowing for maximum light reflection and dispersion.


Grading Scale: Ranges from D (colourless) to Z (light yellow or brown).
Even subtle variations in colour can significantly influence a diamond's value.


  1. Cut: The Artistry of Light Interaction


Cut refers to the precision of a diamond's facet arrangement, proportions, and finishing details.


  • Key Factors: Proportions, symmetry, and polish.
    These determine how effectively a diamond interacts with light, affecting its brilliance, fire, and scintillation.

  1. Carat Weight: A Measure of Size


Carat is a unit of weight, where one carat equals 0.2 grams.


Value Correlation: Larger diamonds of equivalent quality are typically more valuable per carat due to their rarity.
Consideration: While important, carat weight should be balanced with other quality factors for optimal beauty and value.
