Fake Ruby
A variety of Ruby
What is Fake Ruby?
Fake Ruby is a synthetic or natural material that is designed to imitate the appearance of a natural Ruby. A popular type of fake Ruby includes glass, synthetic corundum, and cubic zirconia. Unlike the natural ruby, fake Ruby offers consistent color and clarity, enabling jewelers to craft a more uniform and visually appealing piece. Since a genuine ruby is rare, a large specimen is highly valuable and costly. In contrast, fake Ruby can be produced in larger sizes without such constraints, making it significantly more affordable. However, it may not retain its value over time.
