Emerald is the representative of all green transparent stones. When it comes to bright colors, even the words 'green emerald' are used. The emerald has a low specific gravity, so even if the particles are small, it looks bigger than the same carat number of diamonds or rubies, which is characteristic of it. In the emerald, there are often many inclusions of the 'Mersey' that can be seen by the naked eye, so it is often mistaken for cockroaches. In fact, this substance is completely different from the cockroach that will damage the value of gems. It is an inevitable inclusion in the process of crystal formation. It can also be regarded as an evidence of natural gemstones, and it is a factor that makes the emeralds a mysterious veil. However, this is also related to the degree of the problem. If it is too much to damage the beauty of the gemstone, it is not good. Emerald cutting is usually rectangular and occasionally square. This is because the emeralds and the blue crystals themselves are hexagonal columnar crystals, which are cut in the above manner, and are most effective, showing the most beautiful side.
