Emerald value is determined by its color, clarity, cut, and carat weight, with color being the most important factor. The most prized emeralds have a vibrant, intense green hue with a slight bluish undertone.

The most sought-after emerald color is a pure, vivid green to bluish-green with medium to medium-dark tone and strong saturation. The legendary "emerald green" is often associated with Colombian emeralds.

Inclusions, often called "jardin" (the French word for garden), are common in natural emeralds and are seen as proof of their authenticity. Virtually all natural emeralds contain them; a flawless emerald is extremely rare and valuable.

Authenticity is multi-layered. We provide detailed information on the era, hallmarks, and metal testing. For the gemstones, we look for natural inclusions typical of older cuts and treatments. Many of our significant pieces come with a gemological report verifying the emerald as natural.

The emerald cut is a rectangular gemstone cut with cropped corners. It's defined by its step-like facets and large, flat table, which creates a elegant "hall-of-mirrors" effect instead of a scattered sparkle.
