Certified vs. non-certified

Two ways to buy a stone.

01

Certified

Every certified stone carries an independent IGI report documenting its exact cut, colour, clarity, and carat — full confidence, in writing.

02

Non-certified

Ungraded stones offer the same quality at better value. We grade them in person at your viewing so you see exactly what you are buying.

The 4 Cs

What actually sets a diamond apart.

Cut

The most important C — it governs how light returns to the eye. We favour Excellent and Ideal cuts; a well-cut stone outshines a larger, duller one.

Colour

Graded D (colourless) to Z. Bright, white stones in the D–H range read cleanest; set in the right metal, even faint warmth flatters.

Clarity

From FL/IF through VVS, VS, SI. We select eye-clean stones so inclusions never interrupt the sparkle.

Carat

Weight, not size. Two stones of equal carat can look very different by cut and shape — we balance presence, proportion, and budget.
