a lot longer than that.
Synthetic corundum, spinel and others have been around for over 120 years, and optically transparent uncoloured sapphire glass for over 80 years. They are just aluminium oxides.
ALON is just the new hotness, and not as good as some others in terms of visible light transparency.

Aluminium Oxide (Al~2~O~3~) can be crystal clear too, it’s just Sapphire, I have a chunk of it on my wrist right now, looks pretty clear to me, and almost as hard as a diamond.
