All our finished products leave our Tuscan premises pre-sealed. Since we do not like to paint the surface of our lovely stones with transparent paints or resins, we apply three coats of the highest possible level of protective sealant. This helps to preserve the product without compromising the wonderful natural look and feel of the stone.
That said, please bear in mind that there is no sealer on the market that can make natural stone 100% stain proof, especially if you leave the staining agent on it for a prolonged period. The sealant acts as a temporary barrier that allows you to have a few hours between the moment a staining substance (for example, wine or coffee) comes into contact with the stone and the moment you wipe it off. The important thing is to act quickly before a substance is absorbed into the stone, as that is when it causes staining.
Please DO NOT use cleaners containing abrasive cleansers, ammonia, bleach, acid or even those “homemade remedies” made from lemon, vinegar and the like.
If you are a particularly assiduous cleaner or you have difficulty removing a mark, you can use specialist stone cleaning products and, if to set your mind at rest you can periodically apply a new coat of sealant.
For cleaning stone, wood and metal, simply use a soft cloth with water or a neutral detergent.

Please avoid using detergents on wood and always dry it carefully after cleaning to prevent streaks or patches forming.
Remember that wood is a natural material and can be delicate and photosensitive. Exposure to light, heat or damp may cause slight discolouration or minor adjustments in size, but this is entirely normal and shouldn’t be considered a defect.


As a rule, all orders destined within Italy should arrive within 1-3 working days, whilst for countries within the EU the estimated delivery time is 2-6 working days and 8-10 for other destinations.

Product description

A sustainable texture that is produced exclusively to order, Lost Stones represents a new concept in interior design. It is not available in standardised formats, but instead every slab is bespoke cut, based on the type of stone itself and the environment it will be installed. While this signifies a revolution, tradition is not neglected, with the golden seams that run through the texture a homage to the ancient Japanese art of Kintsugi which used liquid gold to repair broken objects and give them a new life. The Lost Stones story began in 2019 when Gabriele Salvatori and Piero Lissoni realised how much beautiful natural stone was lying around, abandoned and unloved, in yards and warehouses. With the idea of Kintsugi already in mind, they set out on a trip around Italy and unearthed forgotten treasures such as leftover stone from buildings such as Paris’s Notre Dame cathedral and Mies Van Der Rohe’s famous Barcelona Pavilion. They brought them back to Tuscany where the Salvatori artisans set to work to restore them not only to their former glory, but to give them a stunning new incarnation. The Gris du Marais® version of Lost Stones sees the marble’s glorious dappled brown-grey tones set steaked by the golden seams to create eye-catching, truly unique walls and floors that exude warmth and understated glamour.

Good to know

You may see subtle copper-coloured veins running through this stone. These are not defects, but are a part of the stone itself.

The images shown on this page are indicative of the colour and characteristics of our products but cannot be 100% representative. Being made from natural materials, every tile or slab is unique in terms of tonality, colour and characteristic.

These are all subject to variation depending on the type of stone and the conditions in the quarry from where it comes.
