Callisto Granite

A silver stone with grey flecks, Marshalls' Callisto Granite can be used across a variety of applications.

With options including bespoke street furniture and planter veneers, as well as kerbs, steps, edgings, water management solutions, paving and setts, it provides the hard-wearing yet attractive quality that granite is known for.

Callisto comes in 3 finishes. Both the fine picked and flamed finishes are ideal for use in vehicular trafficked and pedestrian areas thanks to their non-slip, non-skid qualities, whereas the polished finish is better suited to street furniture, cladding or internal projects.

Whether a small or large-scale project, Callisto Granite has the flexibility to be used entirely on its own or mixed with other colours from the extensive Marshalls range. All Marshalls granites are fully tested to the appropriate standards in the UK and where relevant UKCA marked in accordance with the latest legislation.

Ethical Risk Index

This Radar diagram illustrates the level of ethical risk associated with a specific stone. Ethical risk is plotted against the 10 ten measures of the ERI, with each value drawn from reports produced by independent ethical auditors, engaged by Marshalls to provide non-biased and honest reporting into levels of risk in that supply chain.

Each of the 10 measure is designed to recognise different and discrete sources of ethical risk. This produces a bespoke, fit for purpose framework designed specifically for the requirements of the stone industry. The radar diagram itself also compares the Marshalls supply chain to the wider industry in that stone, giving users a working comparison of Marshalls supply chain to the industry average, in the opinion of the auditor.
