Looks bronze tinted to me from your photo, and says it on the bottom! (bronce=bronze in spanish I believe)
That's what I thought.
It is bronze mate exactly the same as mine
What did the buyer state the issue was?
You can clearly see the bronze tint in the photo
My bronze tint glass that I have seemd alot darker and and when you put a piece of white pspere behind thr glass it looked clear
I'll agree with vessy there it does seam the sun has done some damage to the tint in this piece of glass,
Mine are also darker although not by much
If thats whats written in the glass, then it is bronze tint, thats exactly whats written on mine and mine are bronze tint in my Antibes
