Buy glass crystal

Good morning,

I am writing to inquire for a glass crystal, preferably gorilla glass or at least hardened/mineral (like in watches). I need two types, one tinted black about 80% and another tinted dark red (red mixed with black). I attached a drawing with dimensions in millimeters. I would love to buy a few, for example ten of each, to check the colours before ordering a bigger batch. After confirming colours and dimensions I can estimate that I will need 2000 of such glass pieces annually.
