Stones from here
What comes out of Minas Gerais.
Brazilian Soapstone
Soft gray · charcoal · green. Chemically inert and heat tolerant, with a surface that develops patina.
Best for: Laboratories, sinks, fireplaces and tactile kitchens.
Watch for: Softness is a feature only when the owner accepts patina.
Minas Slate
Graphite · green · rust · black. Brazil is a major slate producer and Minas Gerais holds an enormous reserve.
Best for: Floors, walls, roofing and hearths.
Watch for: Layer separation and surface texture must match the application.
Amazonite Mineral Surface
Turquoise · mint · cream · smoky matrix. Lead- and water-related structural color in microcline creates the rare blue-green feldspar appearance.
Best for: Backlit features, furniture, bars and protected collector surfaces..
Watch for: Market panels can combine fragments, resin and backing from several sources; disclose the full assembly.
Hematoid Quartz Surface
Crystal · red · copper · golden inclusions. Iron inclusions turn otherwise clear quartz into flame-like red and gold optical material.
Best for: Backlit features, furniture, bars and protected collector surfaces..
Watch for: Natural-inclusion percentage, color treatment, resin and backing require written disclosure.
