Gem Knowledge

How to evaluate a Gemstone

Fine gemstones are assessed on four core criteria — the 4Cs. Understanding them helps you appreciate quality and make confident purchasing decisions.

Vibrant color saturation
Eye-clean clarity
Precision cut & polish
Accurate carat weight
C
Color

Hue tone and saturation are the three axes of gem color. Rich evenly distributed color commands the highest premiums in the market.

C
Clarity

Refers to internal inclusions and surface blemishes. Eye-clean stones (no visible inclusions to the naked eye) are generally most desirable.

C
Cut

A well-executed cut maximises brilliance and minimises windowing. Cut style — round oval cushion etc. — also affects perceived size.

C
Carat

One carat equals 0.2 grams. Rarity increases rapidly with size — a 2 ct stone of equal quality is worth far more than two 1 ct stones.
