Also the danger for you, as the contractor, is that most glass tiles will look different once installed. What are you going to do when the light almond glass tile you showed the customer turns a greenish color when installed?

Search for Typhon Bordeaux right at the top of the page. Search in photos and then in the kitchen forum. You will gets lots of ideas that you can narrow down and then show your customer.

I would go with a glazed crackle to give her that "glass" look, but not be glass.

What, exactly, is your role in this project? Are you a granite fabricator? A handyman? A licensed GC?

I don't know what your client has in mind completely. It might be worth asking the client for some inspiration pictures for what she has in mind.

I think some glass mosaics might be overpowering for that granite. But there are some glass mosaics that might work as long as they are very plain.

Super white glass tile

Maybe something like this with a tiny bit of pattern:

Silver planks glass tile

Or maybe this one which might work with the colour in the counter:

glass mosaic - raw silk

Ugh! Please don't do the multi-size rectangular mosaics linked above. I know they are all over Home Depot and Floor & Decor, but have been overused for 10+ years, starting in high end tile stores about 15 years ago. Even in a plain color, they will be too busy for the Typhoon Bordeaux.
