Machine finish – literally, badlands; refers to dark-coloured rock, commonly lava, in rough terrain. As defined for architectural use: calcium carbonate with other components which give it colour, markings and texture suitable as a desirable building china granite .
china marble  (scientific definition) - a metamorphic recrystallized limestone composed predominantly of crystalline grains of calcite or dolomite, or both, having interlocking or mosaic texture, marble that contains less than 5% magnesium carbonate may be termed calcite marble; from 5 to 40 % magnesium carbonate, magnesium carbonate, magnesium or dolomite marble. These limiting values are, however, not strictly established in petrologic science and are used herein as arbitrary limits.

Onyx – so called in trade, is a crystalline form, commonly micro crystalline, of calcium carbonate deposited usually from cold-water solutions. It is generally translucent and shows a characteristic layering, the term onyx marble is technically a misnomer, as true onyx is a variety of cryptocrystalline fibrous silica (chalcedony), and is closely related in form and origin to agate.

Serpentine – marble characterised by a prominent amount of the mineral serpentine.

Travertine – a form of limestone precipitated from ground waters as in caves or in orifices of springs (see limestone).

Verde antique – a commercial marble composed chiefly of massive serpentine and capable of taking a high degree of polish. Verde antique is not a true marble in the scientific sense but is commonly sold as a decorative commercial marble and requires the adjective modifier Verde (or verd) antique. Verde antique is commonly veined with carbonate minerals, chiefly calcite and dolomite.

Masonry – built up construction , usually of a combination of materials set in mortar.
Metamorphism – the change or alteration in a rock cause by exterior agencies such as deep-seated heat and pressure, or intrusion or rock materials.
Miter – the junction of two units at an angle of which the junction lines usually bisect on a 450 angle.
Modular multiple-cut (pattern-cut) – this refers to standard pattern used throughout the stone industry. These patterns are usually based on multiples of a given height. Stone that is multiple cut or pattern cut is pre-cut to allow typically for ¼ - ½ inch (6 or 13mm) joints or beds.
Mouldings – decorative stone deviating from a plane surface by projections, curved profiles, recesses or any combination thereof.
Mortar – a plastic mixture of cement, lime, sand, and water used to bond masonry units.
Mosaic – a veneering which is generally irregular with no definite pattern. Nearly all the stone used in a mosaic pattern is irregular in shape.
