The key to deciding between a domestic slate and an imported slate is really a color decision. Almost all domestic slates weather to some degree due to the small amounts of iron and other elements in the stone. Most imported slate is non-weathering which is, depending on the desired effect, why it is worth importing in the first place.

If the earth tones and natural variation provided by weathering and semi-weathering slate is desired you are better served by the domestics. Vermont Unfading Green and Purple are the least weathering Vermont slates and sometime experience none at all that is significant enough to be visible from the ground.

If you want a non-weathering black or gray slate, you are probably better served by the imports.

There are a few crossover products on both sides with a lengthy explanation deserved to understand them fully. We will be happy to provided more detailed information upon your request.

You can find good and bad slate in both domestic and imported products, so the key is dealing with a reputable producer like Black Diamond Slate™ and a few others in the slate business.
