What to Know Before Buying a Diamond: The Essential Guide to the 4Cs

When buying a diamond , knowledge is your most valuable tool. The value, beauty, and uniqueness of each gem are determined by the famous 4Cs : Cut, Color, Clarity, and Carat .

We at Atelier Diamanti e Gioielli guide you through these crucial factors to ensure you get a certified diamond and perfect.

1. Cut – The Diamond Cut: The True Light

The cut is not the shape (like round or princess ), but the skill with which the diamond It reflects light. A well-cut diamond appears bright and vivid; a poorly cut one appears dull.

• Ideal Cut: An Ideal Cut diamond —like ours—has perfect proportions and symmetry. It reflects light evenly, maximizing:

  • Brilliance: The reflected white light.

  • Fire: The dispersion in rainbow colors.

  • Scintillation: The visible flashes of light in motion.

Expert Tip: A great cut can make the look jewel bigger and brighter, even at the same carats.

2. Color – The Color of the Diamond: Return to the Colorless

Colorless diamonds are the rarest and most valuable. Color is rated on a scale from D (colorless) to Z (highly colored) .

• Key Categories to Buy:

  • DF (Colorless): Highest quality, ideal for solitaire and engagement rings .

  • GJ (Almost colorless): Excellent balance between quality and price.

  • K (Lightly Tinted): Visible yellow tint.

📌 Note: Mounted in a ring , the difference between hues (such as F and G) is often imperceptible to the naked eye.

3. Clarity – The Clarity of the Diamond: Purity and Imperfections

Clarity measures the presence of internal ( inclusions ) or external ( blemish ) imperfections. The clarity scale is crucial for the diamond value .

Optimal Grades for Quality/Price:

• VS1–VS2: Very slight imperfections, invisible to the naked eye. They are the best compromise.
• SI1–SI2: Small inclusions, generally not visible without a lens, but require careful selection.
• IF–VVS: Near perfect clarity, extremely rare and expensive.

4. Carat – The Weight of the Diamond: Size vs. Quality

Carat (ct) measures the weight of the diamond (1 carat = 0.2 grams). It's often believed that size is everything, but that's not the case.

• Exponential Value: I large and pure diamonds They are much rarer, which increases their value exponentially.
• Priority: Choosing the ideal carat depends on taste and budget, but it is almost always better to choose an excellent cut and color over a slightly lower weight.

Key Features:

• Most diamonds lose up to 65% of their rough weight during cutting
• Large, pure diamonds are much rarer → exponential value

📌 Choosing the ideal carat depends on taste, budget, and proportion to the setting. It's often better to choose an excellent cut on a slightly lighter weight.
