I think everyone has a different idea of what Sage Green is.

I personally think it has a silver tone, but here are some I have seen.

Amazon green

Typhoon green

Green river Surf Green

I have Costa Esmeralda. Mine leans blue-green, and in certain lights looks like a soft blue-grey. The color of costa varies widely -- very widely. Some are light, some dark, some blue-green, some more of a true light green, some a putrid pea-soup green, some with ugly pink streaks in them, some with a lot of white, some with little white, some more grey. This is one of those stones you have to keep looking until you find what you're looking for because it's all over the board, and if you see a slab you like tag it and don't look back. If you can find it at all...

Here is mine. 3000K undercabinet lights are on, bringss out the green:

ETA: RedRyder has a gorgeous grey-green counter that might be more of what you're looking for. I hope she sees this and chimes in.

Wow, Gorgeous!!! If I could find a slab like that I’d be so happy! The ones in my area seems pretty deep blue-green, which I do like objectivly, but not really a good match for anything else in the kitchen.

"The ones in my area seems pretty deep blue-green..."

Oh, that sounds lovely to me!

This is an in person search, with the help of your chosen fabricator and his importers and wholesalers. NOT online. Have DEEEEP pocketbooks. Green is THE hot color of the moment.

I agree that Coasta Esmeralda seems to be closer to a sage green than most any other granite.

Interesting article re green granite and I think the one below has a nice mix of sage. Given the variations, it will suit more cabinet, backsplash and flooring options.
