Classification

How we describe natural stone: petrographic families, colour, finish, fabrication and application, with precise terminology.

STILLSTONE / Natural Stone

Five independent axes

A stone is described once, but can be found five ways: by petrographic family, colour, finish, fabrication method and application.

STILLSTONE / Natural Stone

Terminology, precisely

The distinctions that matter when a material is specified.

Natural stone only

We supply natural dimension stone. Engineered quartz, sintered stone, porcelain and ceramic are not listed as stone families.

Quartzite ≠ quartz

Quartzite here is a natural metamorphic or quartzitic sandstone, not an engineered resin-bound quartz surface.

Onyx

Trade onyx is banded calcite deposited by water — not the silica chalcedony gemstone. It is usually translucent and resin-backed.

Dolomite

Dolostone and dolomitic marble are listed separately from marble: they are harder and behave differently under acid.

Travertine

Travertine is a variety of limestone, but is listed separately because its porosity, filling and vein-cut directions change specification.

Serpentine

Serpentine is commonly sold as green marble. It is not marble, and its polish and weathering behaviour are different.

Commercial granite

The granite group follows industry practice: gabbro, basalt, diorite, anorthosite and gneiss are grouped by performance, not by strict petrography.

Trade groupings

Culture Stone, Gemstone & Semi-Precious and Rare & Exotic Stone are trade groupings, not geological classes; we describe each lot individually.

Finishes

A finish is a surface treatment, not a stone type. Not every stone accepts every finish; we confirm compatibility against the current lot.

Colour

Colour families are a guide only. Natural stone varies between blocks and should always be approved from a current sample or slab photograph.
