📚 Emerald Grading Guide

Why Emerald Grading is Different

Unlike diamonds, emeralds require specialized knowledge due to their unique "jardin" inclusions. What matters most is how inclusions affect transparency and structural integrity.

Colombian vs Zambian Origins

Colombian emeralds command 30-50% premiums due to legendary color saturation. Zambian emeralds offer better clarity and can compete with Colombian material in quality.

FAQ

How to tell if an emerald is good quality?
Look for vivid green color, eye-visible clarity without black inclusions, minimal oil treatment, and proper proportions. Always request GIA certification for emeralds over $1,000.
Are Colombian emeralds always better?
Not necessarily. A top-grade Zambian can rival an average Colombian. Zambian emeralds often have better clarity and durability for daily wear.
What does F1 F2 F3 mean?
GIA treatment codes: F1=minor oil (trace), F2=moderate oil (noticeable), F3=heavy oil/resin. F1 emeralds sell for 2-3x the price of F3.
How much per carat for emeralds?
Commercial: $300-800/ct. Fine: $2,000-8,000/ct. Exceptional Colombian untreated: $10,000-50,000+/ct.
