Sapphires are used in the making of jewelry and as hard bearings in watches and scientific instruments.
Synthetic sapphires make specialty windows and shatter-resistant ones in armored vehicles. It is also used in various military body armor suits with composites.
Sapphire wafers are used in the microchip industry for high-power radio-frequency (RF) applications, such as those found in cellular telephones, public-safety band radios, and satellite communication systems.

Sapphire is a highly sustainable material that is known for its durability and scratch resistance. Made from naturally occurring mineral corundum, Sapphire is a naturally abundant material that can be easily sourced, and it is also highly recyclable. Sapphire is used in various applications, including electronics, optics, and jewelry, and its recyclability makes it an excellent candidate for a circular economy. Recycled Sapphire can be used to make new products, reducing the demand for new materials and decreasing the environmental impact of manufacturing.
