What makes diamonds different from other gems, is that diamonds are formed from a single element, this being high pressured carbon.
When buying a diamond the quality is determined by the 4C’S
Cut: Quality of the angles, proportions, facets and the finishing details
Colour: How clear is the diamond. This is rated from A- Z. A is colourless and as you go further the colour changes to yellow
Clarity: How clean is the diamond of inclusions and blemishes which are formed naturally within the diamond
Carat: The weight of the diamond
When purchasing a diamond you will never find two the same due to the formation process.
Simply put, diamond formation occurs when carbon deposits deep within the earth(approximately 90 to 125 miles below the surface) are subject to high temperature and pressure. Some stones take shape in a matter of days or months, while others take millions of years to materialise. Additionally, it’s almost impossible to determine a diamond’s exact age
