An Emerald Gems is usually graded visually – its colour should be a typical hue of dark green that has yellow and blue as secondary colours, and it should be pleasant (and not warm) to the touch. It’s common for emeralds to be cracked, so a good eye and a sensitive touch can detect if it’s flawless or not. Emeralds Gemstone may be treated with oil to enhance their transparency and excellence.
