Emerald and other Beryl Stones are a class of expensive and vibrant colored stones that can simply enhance the personality of the wearer. The naturally occurring beryl is basically colorless, but owing to color of foreign substances makes the stone appear colored. The price factor largely depends on color of the gemstones. The rare the color of the stone, more expensive it is. You can find stones in the range of as low $50 and can go to $ 5000 and even more. Price of the stones also depends on the prevailing market forces, as well as the metal in which the stone is studded. Sometimes the polishing of the stone adds to the value of the stone and it can be sold at higher prices. Other important aspects that need to be considered are the clarity as well as the size of the stone. Besides, the stones of very fine quality lying in the range of 1-2 carat are priced variably between $1500-$4500/carat. The prices can even surge more for the Emerald and other Beryl Stones of very high quality. You can easily estimate the prices of superior quality stones of 5-10 carats, priced at $10,000/carat. But again, these prices are subject to change under the influence of the market as well as the region. The prices of the emerald and the Beryl family of stones have seen a remarkable drop in the stone prices.
