How a semi-precious stone slab is made
It does not come from a block: it is assembled by hand, piece by piece.
- Natural pieces
Slices or pieces of a natural stone (agate, quartz, mother of pearl…) cut and polished one by one.
- Bonded with resin
The pieces are bonded with resin onto a base. In some slabs the joints carry gold or silver leaf.
- Every slab is different
The pattern is a mosaic and never repeats: we send you photos of the slabs before you buy.

Questions about semi-precious stones
Is a semi-precious stone slab made from a single stone?
No. It is assembled by hand from slices or pieces of natural stone bonded with resin onto a base. The pattern is a mosaic, and every slab comes out different.
Which ones can be backlit?
The translucent ones: agates, amethyst, quartz and selenite let light pass through their lighter areas. Tiger eye, malachite, lapis lazuli or mother of pearl are opaque and shine in ordinary room light.
Are they durable?
The stone is: quartz and agate reach 7 on the Mohs scale. The delicate part is the resin that bonds the pieces: it scratches sooner and does not take direct heat. They belong on interior walls, bars, sinks and tables.
