How We Evaluate Diamonds

1

Verify Authenticity & Certification

We inspect any available certification (e.g., GIA, EGL) and use advanced tools to verify the authenticity and grading of your diamond.

2

Weigh and Categorise

Once purity is confirmed, we weigh your gold on calibrated digital scales and categorise it by karat to provide a fair and precise valuation.

3

Market-Based Offer

Based on current diamond market trends and your stone’s characteristics, we provide a fair, obligation-free offer - with no pressure to sell.

Understanding Your Diamonds

Every diamond tells a story of brilliance, rarity, and value. But understanding what makes yours special comes down to the 4Cs: Cut, Color, Clarity, and Carat. Whether you’re selling a loose stone or a treasured piece, knowing how each of these factors impacts value helps ensure you get the best return. Explore the key traits that define your diamond’s true worth.

Cut

A diamond’s cut determines how well it reflects light. Precise proportions and symmetry enhance sparkle, making the piece truly dazzle.

Color

The less color in a diamond, the higher its value. Colorless stones reflect light better, giving your diamond a brighter, cleaner glow.

Clarity

Clarity reflects the absence of flaws. Higher clarity grades mean fewer inclusions, resulting in cleaner, more brilliant diamonds.

Carat

Carat weight measures the size of a diamond. Larger stones make a stronger visual statement and often command premium value.
