Understanding Diamond Quality: The 4Cs Explained
Choosing the right diamond is more than just picking something that sparkles. At Rai Jewellery, we want you to feel confident and informed when selecting a diamond for your custom ring, pendant, or watch. That’s why we educate every client on the 4Cs of diamond quality: Cut, Colour, Clarity, and Carat.
1. Cut
The cut determines how well a diamond reflects light—and ultimately, how much it sparkles. A well-cut diamond will shine brightly even if it has a lower carat weight or clarity. Popular cuts include round, oval, princess, cushion, and emerald.
Pro tip: Always prioritise cut for maximum brilliance.
2. Colour
Diamonds are graded on a scale from D (colourless) to Z (light yellow). Colourless diamonds (D–F) are the most valuable, but near-colourless stones (G–J) often offer great value and still look stunning when set in gold.
Pro tip: Yellow gold settings can make lower-grade colour diamonds appear whiter.
3. Clarity
Clarity measures how many tiny imperfections (inclusions) are inside the diamond. Grades range from Flawless (FL) to Included (I). Most imperfections are microscopic and invisible to the naked eye.
Pro tip: VS1–SI1 clarity grades often provide the best balance of quality and affordability.
4. Carat
Carat refers to a diamond's weight, not its size. A higher carat often means a larger appearance, but the cut can also affect how big a diamond looks.
Pro tip: A slightly lower carat diamond with a great cut can appear larger and save you money.
