Minor Oil (F1) means a small amount of cedar oil has been used to improve clarity. F1 emeralds are widely accepted in the luxury market and represent an excellent balance between beauty and rarity.
What is Moderate Oil (F2)?
Moderate Oil (F2) indicates a more noticeable level of oil enhancement. While still accepted in the trade, F2 stones are less rare and priced accordingly.
Is F1 better than F2?
Yes. F1 emeralds require less enhancement and are naturally cleaner, making them more desirable among collectors and high-end buyers.
Are resin-treated emeralds acceptable?
No. High-end buyers should avoid emeralds treated with artificial resins such as “Permace” or other polymer fillers. Unlike traditional cedar oil, resin treatments can artificially alter clarity in a more permanent and less natural way, reducing long-term value and collectability.
What is the hardness of emerald?
Emerald ranks 7.5–8 on the Mohs scale. While relatively hard, it can be brittle due to natural inclusions, making protective settings advisable.
Can emerald be worn every day?
Yes, with proper care. Emerald rings should feature protective mountings such as halos or bezel settings to minimize impact risk.
Should emeralds come with documentation?
For significant purchases, documentation confirming authenticity, origin (when determinable), and degree of oil treatment is strongly recommended.
Are untreated emeralds more valuable?
Yes. No Oil and Insignificant Oil emeralds are significantly rarer and can command premium prices in the luxury market.
What affects emerald price per carat?
Price per carat depends on:
• Color intensity and saturation
• Transparency
• Carat size
• Geographic origin (in some cases)
• Degree of oil enhancement (No Oil > Insignificant > F1 > F2)
Fine Colombian emeralds with minimal oil treatment can achieve exceptionally high per-carat prices.
