Key Principle
Colour is King
For coloured gemstones, colour is the most important of the four quality factors — colour, clarity, cut, and carat weight. Gemologists judge it across three dimensions: hue (the base colour), tone (how light or dark), and saturation (the colour's intensity and purity). A smaller stone with vivid, evenly saturated colour will almost always outvalue a larger, poorly coloured one.
The second principle: always buy certified. A reputable laboratory report confirms species, origin, and treatment status — protecting your investment and giving you confidence in what you own.
