Ruby

In the current market, colorless or light-colored corundum is sometimes dyed to imitate ruby. Low-quality ruby may also undergo glass filling to enhance appearance. There is nothing wrong with buying treated stones as long as you understand what you're purchasing and pay an appropriate price, as such treated stones are significantly cheaper than natural ruby. Another point to note is that the current market is flooded with numerous lab-created ruby gemstones. 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, Pyrope Garnet, Elbaite, and plastic are occasionally mislabeled as ruby. 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 ruby.
