No oil emeralds are emeralds that are not treated or enhanced with oil. These are natural gemstones from the beryl mineral family. The green color of these stones is due to the presence of chromium elements. Emerald no oil is considered rare and more valuable than diamonds, especially those sourced from Colombia. They make perfect precious gemstones for high investment. Generally, these beryl stones are brittle and get fractured when placed in any jewelry form. Thus, they are treated or enhanced with oil to improve their stability, color, and clarity. No oil green stones are entirely free from fissures and have a clean surface.
About
No oil emeralds are the most desirable natural emeralds mined in Colombia. They are categorized as type III gemstones, meaning they have inclusions from the time they were formed. Treated and no oil emeralds differ in this aspect as well. No oil gems have inclusions called Jardin. They give the stones a moss or garden-like appearance. Only 1% of these gemstones show a pure green hue and high transparency. These stones command a high price. The gemstone marketplace is flooded with treated stones. The fractures are filled with cedarwood oil, giving these beryl stones an astonishingly bright look. They make the stone appear perfect, but they come with a disadvantage. The oil dries out, and one needs to reapply it with the help of a professional jeweler. Thus, no oil stones are a safe investment. The beauty of these gems remains for long.
Jewelry

Quality
These gems from the beryl mineral family are highly coveted. With no oil treatment done to these, they are in their natural state. This is a top-quality emerald that shines without any artificial treatment. These stones are sold in the market differently, like “no oil “ or “significant oil.” No oil treatment means that no enhancement has been done to the stone. “Insignificant oil” has minimal oil treatment, whereas significant stones add enough oil to fix the fissures. The quality of the gem depends upon its color and clarity. So, if these stones possess both characteristics, they are high quality.
Price
Emerald no oil is rare gems that are untreated. The no-oil emerald price starts from US$600 and can extend more depending upon the per-carat weight. Let’s see what are the factors that impact the cost of the stone:
Origin: These can be found in various places such as Brazil, Zambia, Zimbabwe, etc. However, the top quality is found in Colombia. Three mines are famous here: Muzo, Chivor, and Coscuez. Those obtained from the Chivor and Muzo mines are the significant ones.
Color: The most valuable ones are those with rich green color, medium tone, and high saturation. Gems with minimal or no color zoning are considered the best quality natural beryls and command the highest prices. The color ranges from light green to dark green. The darker and too-light hues are slightly less expensive. This is because they interfere with the brilliance of the stone.
Clarity: These vibrant green stones are known to possess inclusions called “Jardin.” No oil emeralds with no or minimal inclusions are called rare and expensive. The quality of these stones depends upon high transparency and refined color. However, you can expect inclusions in some specimens as these are untreated gems.
Cut: A well-cut stone affects its brilliance and overall appearance. These green gemstones can be cut in round, pear, octagon, marquise, and other shapes. The natural beauty of the stone is best reflected if the gem is symmetrically cut. Fine facets reflect the depth of the color, making it shine on your jewelry piece.
Carat Weight: Larger untreated no oil emeralds are valuable. As the carat weight increases, so does the price per carat. High-quality gems with specific colors, high clarity, and defined cuts account for higher prices.
Care and Cleaning
To maintain the brilliance of these gems, clean them with soapy water. Gently scrub the surface with a soft-bristled brush. This is the best way to clean gemstones at home.
– Keep the stone away from harsh chemicals such as bleach, ammonia, or strong detergents and extreme temperatures.
-Professional cleaning is necessary. A professional jeweler inspects the gemstone setting and metal. If the settings are loose, they can be fixed to avoid missing your precious gem.
