Calacatta Gold Supreme by iStone

Calacatta Gold Supreme is an engineered quartz surface: crushed natural quartz bound with polymer resin and pigments. It is a manufactured material, not a natural stone. iStone does not publish a breakdown of its material here, so we cannot quote a percentage.

Our listing shows Calacatta Gold Supreme in a polished finish and 20 mm and 30 mm thicknesses. Our listing shows a polished finish and 20 mm and 30 mm thicknesses; iStone's website does not state them for this colour, so we confirm the finish and thickness in your quotation. Your quotation states the finish and thickness we have priced.

For everyday cleaning use a soft cloth with warm water and a little mild washing-up liquid, and wipe up spills promptly. Use a chopping board rather than cutting on the surface, a trivet or heat mat under hot pans, and avoid bleach, abrasive pads and harsh cleaners.
