4 c's of a diamond

What are the 4C’s?

• Carat: Is the size a diamond is measured in, referring to the weight - one carat is equal to approximately 0.2 grams. Size does matter but a low quality big diamond won’t sparkle as beautifully as a smaller high grade diamond. Most common sizes used in solitaire engagement rings are .25ct, .50ct, .75ct, 1.0ct and sometimes higher.
• Cut: The quality of the stone’s proportions, polish and symmetry. The perfect cut is based on a mathematical formula and determines overall brilliance. Ideal and excellent cut stones are going to give you the most reflects/fire in combination with the other 4 C's.
• Clarity: Most diamonds naturally have trace impurities or other tiny imperfections that can detract from the pure beauty of the stone. Flawless diamonds are the rarest and most sought after. The colour scale for transparent diamonds runs from D-F (colourless), G-J (near colourless), K-L (faint yellow), to Z (light yellow).
• Colour: Like a prism, a well cut stone divides light into a rainbow of colours, reflecting as flashes of ‘fire’. Any colour in the stone itself acts as a filter so the clearer and whiter the diamond, the better the ‘fire’.
