FREQUENTLY ASKED QUESTIONS

Why are non-oiled emeralds particularly valued in the collector market?

Non-oiled emeralds represent extraordinary rarity – less than 1% of all emeralds remain completely untreated. Their natural clarity and color exist without enhancement, demonstrating exceptional crystal formation. GIA-certified non-oiled emeralds command substantial premiums, often 100-300% above similar-appearing oiled stones, making them both prestigious acquisitions and potentially excellent investment-grade precious stones with long-term appreciation potential.

How can buyers verify a genuine non-oiled emerald?

Laboratory certification from GIA or equivalent reputable organizations is absolutely essential, specifically stating “no oil” or “no clarity enhancement” in the report. Advanced microscopic examination by qualified gemologists can identify the characteristic inclusions and growth patterns of natural, untreated emeralds. Purchasing from established dealers specializing in high-quality, conflict-free gemstones provides additional assurance when acquiring these rare and valuable stones.

Do non-oiled colored gemstones require special care or maintenance?

Non-oiled precious stones actually require less maintenance than their treated counterparts, as there’s no enhancement material to deteriorate over time. Their natural durability means they can be cleaned more thoroughly, including ultrasonic cleaning methods that would damage oiled stones. The pure, untreated nature of these gems ensures they maintain their original beauty indefinitely with standard care, representing both aesthetic perfection and practical longevity.
