Emeralds, prized for their vibrant green hues, are naturally formed with inclusions, often referred to as jardin. To enhance their clarity and appeal, oiling is one of the most traditional and widely accepted treatments. In this article, Oiling’s Role in Emerald Clarity, we explore how oiling improves the appearance of emeralds, the types of oils used, and the durability of this treatment.
How Oiling Enhances Emerald Clarity
Oiling is a process that involves filling surface-reaching fractures in emeralds with a clear, natural oil to reduce their visibility.
- Improved Clarity: By minimizing the appearance of inclusions, oiling enhances the transparency and brilliance of the gemstone.
- Color Enhancement: The treatment can also improve the perception of the emerald’s color by reducing internal reflections caused by fractures.
- Market Appeal: Oiling allows emeralds with natural inclusions to appear more visually appealing, making them desirable for jewelry applications.
This method is non-invasive and preserves the gemstone’s natural structure, making it a widely accepted practice in the gemstone market.
Types of Oils Used in Treatment
The type of oil used in emerald treatments can vary, but the most common is cedarwood oil.
- Cedarwood Oil: A natural, clear oil that closely matches the refractive index of emeralds, making inclusions nearly invisible.
- Synthetic Oils: Occasionally, synthetic alternatives or specially formulated resins are used for more durable results, though these require disclosure.
- Considerations: The use of natural oils is preferred for their reversibility, maintaining the gemstone’s authenticity while enhancing its clarity.
The Durability of Oiled Emeralds
While oiling improves an emerald’s clarity, its durability depends on proper care and maintenance.
- Temporary Treatment: Over time, oil can evaporate or degrade, especially if the emerald is exposed to heat, harsh chemicals, or ultrasonic cleaning.
- Reapplication: Oiled emeralds may require periodic reapplication to maintain their enhanced clarity.
- Care Tips: To preserve the treatment, emeralds should be cleaned gently with a soft cloth and mild soap, avoiding exposure to extreme conditions.
Despite its temporary nature, oiling remains a trusted and reversible method for enhancing emerald clarity.
Oiling’s role in emerald clarity is crucial in improving the gemstone’s transparency and overall appeal. By understanding the process, the types of oils used, and the care required for oiled emeralds, buyers can make informed decisions and appreciate the craftsmanship behind these timeless gemstones.
