Why is Sapphire Crystal so expensive?
Sapphire crystal is a synthetic material made by crystallizing pure aluminium oxide at very high temperatures. Due to it’s hardness, advanced diamond-coated saws are required to polish and cut the material into circular discs with meticulous precision, making it an extremely expensive process to perfect.

Sapphire Crystal vs. Mineral Crystal - how to choose
The most expensive of all the watch crystals, sapphire crystal is highly regarded for its scratch and shatter resistance. It’s rated 9 on the Mohs scale for hardness, meaning it can only be scratched by itself or diamonds, and is a superior choice over mineral crystal over time.
Pro tip: Sapphire crystal is highly reflective, so we recommend looking for sapphire crystal with multi-layered anti-reflective (AR) coating when shopping for your next luxury watch.
