1. Its True Identity Lab Created orange sapphire compare with Natural orange sapphire, Both are identical materials and have the same molecular makeup.Lab-grown synthetic orange sapphires have the same physical properties-Aluminum Oxide, Al₂O₃), visual characteristics and hardness level as the natural gemstones. Simply put, it is a "real gemstone," except it's born in a high-tech lab rather than deep underground in nature.  Advantage: In the natural gemstone world, orange sapphires with vivid, highly saturated colors are extremely rare and typically very expensive. The emergence of cultivation technology aims to replicate this beautiful color at a much lower costand it can even create tones that are purer and more intense than natural stones-often a fraction of the cost of natural orange sapphire—making it perfect for daily wear and accessorizing.
