emerald stone rate The price of emeralds is determined much like any other gemstone. It’s about color, cut, carat, and clarity. In the case of emeralds, origin and treatment are additional factors. The cut is important but cuts can be adjusted and upgraded if access to a skillful cutter is a possibility. Most emeralds are emerald or octagon cut because that shape will normally produce the largest stone from tabular emerald rough. Other shapes are arguably more desirable because they’re always in short supply but still, emerald cuts are always popular. The cut is directly related to both the weight, and the luster of a stone so its implementation is significant and consequential. The carat weight is important for any gemstone. Large gems are always rare in nature so the rule is, “bigger is better”. A stone that’s too big can always be cut down so too big is never an issue. Clarity is critical in emeralds and cleaner is better. Emeralds are a Type III gemstone, as rated by the Gemological Institute of America (GIA) which means they are normally included. Although potential emerald buyers may expect their emeralds to be clean, this is rarely the case and emeralds are usually oiled or in filled with resin to improve their clarity. The idea is to fill up any cracks, crevices, or fractures with a liquid or resin of a refractive index similar to emerald in order to hide or even disappear them. And it works even though oiled stones may require another oiling at some point in. Oiled and resin filled emeralds look better but some stones are clean enough and don’t require any treatment and those stones are worth the most in terms of clarity. Color is considered to be the most important factor in determining valuations. The best colors are the highly saturated shades of green or bluish green. Any yellowish modifiers are likely to reduce value but high saturation and purity of color are essential for emeralds to be considered top. The best and the most expensive emeralds are agreed to be Colombian in origin but great looking emeralds are also mined in Zambia. Some nice emeralds also occur in Brazil. Russia, Madagascar, Ethiopia and other parts of East Africa also produce some attractive emeralds but production is limited.
