Understanding Diamond Grading
When buying a diamond online or in-store, professionals evaluate it using a global grading system called the 4C’s : Cut, Color, Clarity, and Carat Weight. These four parameters determine the diamond’s appearance, quality, and price.

The 4C’s of Diamond Quality: Cut, Color, Clarity & Carat Weight
Find the perfect piece of ethical and affordable fine jewellery to celebrate you or the one you love.
✨
CUT – The Sparkle Factor
Cut is what defines how beautifully a diamond reflects light. A perfectly cut diamond ensures maximum brilliance, fire, and sparkle even in smaller sizes. Every Pure Jewels diamond is precisely cut and polished by skilled artisans using advanced technology to ensure ideal proportions and symmetry
🌟
COLOR – The Shade of Purity
Diamonds are graded on a color scale from D (colorless) to Z (light yellow). Colorless diamonds (D–F) are the most sought after, while near-colorless diamonds (G–I) provide excellent value for money. Our Pure Jewels lab-grown diamonds maintain high color grades to deliver maximum shine and brilliance.
🔍
CLARITY – The Inner Perfection
Clarity measures natural inclusions or blemishes within the stone. Flawless and VVS diamonds offer maximum sparkle, while VS and SI clarity diamonds balance beauty and affordability, ideal for everyday wear or gifting. All our diamonds come IGI or SGL certified for transparency and trust.
⚖️
CARAT – The Weight of Elegance
Carat refers to the weight and size of the diamond. Larger diamonds are rarer and more expensive, but smaller stones with superior cut quality can offer even better brilliance. At Pure Jewels, we offer lab-grown diamonds in all sizes from 0.10 carat solitaires to 3 carat statement stones ensuring options for every style and budget.

The 4Cs : Cut, Color, Clarity, and Carat Weight are the global standards used to assess a diamond’s quality, beauty, and price.
Which of the 4Cs is most important when buying a diamond?

The Cut is the most important C because it determines how much a diamond sparkles and reflects light, even more than size or color.

Diamond Cut refers to how well the diamond has been shaped and polished, affecting its brilliance, fire, and overall sparkle.

How does Clarity affect a diamond’s appearance?

Clarity measures how free a diamond is from inclusions or blemishes, the higher the clarity (like VVS or VS), the more radiant the diamond appears.
What does Carat mean in diamonds?

Carat is the weight and size of the diamond. Larger carat diamonds are rarer, but smaller diamonds with an excellent cut can look equally brilliant.
Are lab-grown diamonds graded by the same 4Cs?
