What is Fake Sapphire?
Fake Sapphire refers to a synthetic or natural material created to mimic the appearance of a natural sapphire. An example of fake Sapphire includes glass, synthetic spinel, cubic zirconia, and synthetic corundum. This material is typically more affordable than a natural sapphire, making it appealing for budget-conscious consumers seeking a similar aesthetic. However, fake Sapphire lacks the value and durability of a genuine sapphire, resulting in a lower long-term value.
