Formed by rapidly cooled extrusions of magma from deep within the mantle, this basalt displays prominent phenocrysts encased in a matrix of dark grey plagioclase feldspar. Scattered throughout are noticeable greenish crystals of olivine.


One of the most robust stones available, Carbon Black Basalt, as its name suggests, has a complex dark character born of its dusky mineral composition.


The versatility of Rhodes Architectural Stone’s Carbon Black Basalt makes it an excellent choice as an architectural veneer, and is well suited for paving, cobbles, and any cut-to-size application.

As you'd expect in a natural product, stone does vary in colour and texture, even in the same quarry block. That's what makes stone so unique.
We recommend using the images on our website to initially chose the colour, texture and look you prefer, then talk to us to see our current samples. Mockups are also a great option before making your final decision. We strive to provide a product of the highest quality, but please remember it's stone, not paint. The colour and texture of the next layer in the quarry was defined millions of years ago.
