Sapphire jewelry. They also may be created synthetically in laboratories for industrial or decorative purposes in large crystal boules. Because of the remarkable hardness of sapphires – 9 on the Mohs scale (the third hardest mineral, after diamond at 10 and moissanite at 9.5) – sapphires are also used in some non-ornamental applications, such as infrared optical components, high-durability windows, wristwatch crystals and movement bearings, and very thin electronic wafers, which are used as the insulating substrates of very special-purpose solid-state electronics (especially integrated circuits and GaN-based LEDs). Sapphire is the birthstone for September and the gem of the 45th anniversary.
Sapphire (satellite) Launch Pad at the Satish Dhawan Space Centre. Sapphire was a secondary payload on the rocket, the primary payload being the SARAL oceanography satellite. NEOSSat, UniBRITE-1, TUGSAT-1, AAUSAT3 and STRaND-1 were also launched aboard the same rocket. Sapphire (satellite) Sapphire is a Canadian space surveillance satellite which was launched in 2013. Sapphire was constructed by MacDonald, Dettwiler and Associates (MDA) based on an SSTL-150 bus produced by Surrey Satellite Technology (SSTL) and an optical payload produced by COM DEV International. Sapphire, Canada's first military satellite, is a small spacecraft designed to monitor space debris and satellites within an orbit 3,728
