Synthetic ruby (Scientific ruby) is a lab-created gemstone made of corundum, the same mineral as natural rubies, sapphires and emeralds. Synthetic rubies are optically and physically identical to their natural counterparts and are highly sought after due to their affordability, durability and beauty. They are also often used in watchmaking due to their hardness and scratch-resistant properties. Synthetic rubies are created using a high-temperature, pressure furnace method and are available in a variety of colors and sizes.
