Diamond Guide

Buying a diamond should feel exciting, not overwhelming. At CITRAI, we believe in clear, transparent information so you can make a confident choice — whether you’re shopping for a natural diamond or a lab-grown diamond.

Natural vs. Lab-Grown Diamonds

Both natural and lab-grown diamonds are 100% real diamonds — identical in chemical composition, hardness, brilliance, and sparkle.

• Natural Diamonds – Formed deep within the Earth over billions of years; prized for their natural origin and rarity.
• Lab-Grown Diamonds – Created using advanced technology that replicates nature’s process; often more affordable and sustainable.

💡 At CITRAI, every diamond — natural or lab-grown — is certified and laser-inscribed for authenticity.

The 4Cs of Diamond Quality

1. Cut

• The most important factor for sparkle and brilliance.
• A well-cut diamond reflects light beautifully, making it appear larger and brighter.

2. Color

• Diamond color is graded from D (colorless) to Z (light yellow/brown).
• Colorless diamonds are rare and valuable, but near-colorless grades often look just as stunning in certain settings.

3. Clarity

• Refers to natural inclusions or blemishes.
• Graded from Flawless (FL) to Included (I). Most diamonds have tiny inclusions not visible to the naked eye.

4. Carat Weight

• Measures the diamond’s size.
• Bigger isn’t always better — cut quality can make a smaller diamond look more impressive.

(Advanced) How GIA Evaluates The Most Popular Shape: Round Brilliant Cut

For round brilliant diamonds, GIA assigns cut grades based on a precise relationship between table size, crown angle, and pavilion angle. The chart below shows how these proportions interact to influence cut quality.

What this means for you:
Diamonds that fall in the Excellent or Very Good zones typically deliver the best balance of brilliance, fire, and value. Minor variations within these ranges are normal and often invisible to the naked eye.
