I’d call a local glass company, they should be able to order this for you. I wouldn’t go non tempered. Expect $$$.

Yes, a local glass shop can definitely order it. Either polished edges or a beveled edge (cannot tell what yours has. I would definitely only go tempered that size and with that much of the top unsupported.

There are companies that specialize in glass tops.. Find one that is close to your location. They likely import in volume and can provide you with a better price than a glass shop cutting one table top. Also, all the tops will be tempered which is required.

A local to you glass shop can usually do this with zero issue. Auto glass shops use tempered glass ! by the mile!

You give them the dimensions. they cut and polish.I do table tops all the time at my local. , and they deliver.

Yes, look for a local glass/shower shop and they can easily make a custom top. I recently had a rectangular glass top made for a desk/console in my guest bedroom. For a pedestal table I would pay extra for Starphire low iron glass, so you get less of a green tint on the glass.

Good advice about low iron glass - or maybe you are ok with regular but just be aware of the difference

Thanks, I called local glass company and am waiting for their quote.
