The Four Cs
The cost of a diamond ring is primarily determined by the Four Cs—Cut, Colour, Clarity, and Carat weight. Each of these aspects contributes to the overall value and appearance of the diamond:

1. Cut: A well-cut diamond will sparkle brilliantly, while a poorly cut diamond might appear dull. The cut also affects the shape, with round brilliant cuts typically being more expensive.
2. Colour: Diamonds are graded on a colour scale from D (colourless) to Z (light yellow or brown). Colourless diamonds are rarer and therefore command a higher price.
3. Clarity: This refers to the presence of internal or external flaws, known as inclusions and blemishes, respectively. Diamonds with fewer imperfections are more valuable.
4. Carat Weight: This is the most straightforward factor—the larger the diamond, the more expensive it will be. However, two diamonds of the same carat weight can have vastly different prices depending on their cut, colour, and clarity.

• Setting and Metal Type
  The setting of the diamond and the type of metal used for the ring band also influence the price. Platinum is generally more expensive than gold due to its durability and rarity. The complexity of the ring’s design and the craftsmanship involved can also add to the overall cost.
• Certification and Brand
  A diamond ring that comes with certification from a reputable grading laboratory, such as GIA or IGI, will typically be more expensive. Additionally, rings from well-known brands may carry a premium price due to their brand reputation and the assurance of quality.
