This 2.86 carats oval shape Natural Emerald is considered to be one of the most precious of all gems. It's a derivative of the mineral beryl and the metal chromium leads to green color that is so famous. This is a perfect Emerald Stone, and usually graded visually. People like psychics, healers, practitioners of any divine arts and astrologers can find incredible progress in their line of work by wearing this stone. It's very common for emeralds to be cracked as they are very sensitive, so a good eye as well as a sensitive touch can detect if it's perfect or not.
