White Marble for Ashlands

[Rand Al'Thor]

I think that the ashlands should have some white (or gray) marble. In real life, Marble is formed by volcanoes heating up limestone, forming the metamorphic rock of marble. As long as we're talking about lava, this is also how diamonds are formed, but I think white marble would fit with valheim more. However, diamonds could be a treasure item like rubies or pearls. White marble could have ridged decorative columns and pedestals. Maybe even a white marble item stand?
