Highly valued as gemstones, emeralds are a grass-green variety of beryl. The capacity of emeralds to deflect light and to break white light into its component colors is not high, so cut stones display little brilliancy or fire (flashes of color). The color that gives this gem its value comes from the presence of small amounts of chromium. The most important production of fine-quality gem material is Colombia; emeralds are also mined in Russia, Australia, South Africa, and Zimbabwe. Synthetic emeralds are identical to natural crystals and may rival them in color and beauty.

However, Acronis will fail to clone a drive when it encounters bad sectors.Generally it will just stop completely.ven if the hard drive did not fail to the point of causing hardware problems, it still could contain bad sectors that might cause issues when moving data from it to a new hard drive.
