Emerald

In the current market, colorless or light-colored beryl is sometimes dyed to imitate emerald with very low price. Most of emeralds undergo oils or resins filling to enhance appearance. While filling-treated emeralds are priced slightly lower than natural ones, they're generally considered genuine. Another point to note is that there may also be lab-created emerald gemstones in the current market. Although they are still considered genuine, sharing the same chemical, physical, and optical properties as natural ones, they typically cost much less than natural ones. Materials such as Glass, Cubic Zirconia, Dyed Quartzite, Fuchsite, and plastic are often mislabeled as emerald. It's wise to purchase from reputable retailers and, if feasible, request a certificate from a gem testing laboratory. Here are some handy tips to help you initially discern the authenticity of emerald.
