Choosing the perfect engagement ring is one of the most meaningful purchases you’ll ever make. Understanding the 4Cs—Cut, Colour, Clarity, and Carat—helps ensure you select a diamond that meets your expectations in both beauty and value.

💎 Cut – Determines how well a diamond reflects light, influencing its brilliance.
💎 Colour – The most valuable diamonds are colourless, graded from D (colourless) to Z (light yellow/brown).
💎 Clarity – Measures the presence of internal or external flaws (inclusions & blemishes), affecting transparency.
💎 Carat – Refers to the weight of the diamond, impacting its size.
