Dark pigments create the illusion of precious stones in this series of geometric concrete furniture by Belgian design studio Sment.
The Gestalt collection is made up of three objects: a tall, cylindrical lamp with a carved out section that helps it gently reflect light back off the polished surface; a seat in the shape of an arch; and a low, ring-shaped table that sits on three squat feet.
Each piece is cast in a mould, with pigments added to the concrete. The material is then polished to create the stone-like final effect.

"We investigated several ways of using pigment," Sment co-founder Jochen Sablon told Dezeen. "The combination of pigmentation with polishing leads to a surreal twist of organic patterns which reminds us of natural materials such as stone or marble." "This together with the basic geometrical form results in an abstract sculpture for every piece," he said.

The aim of the project was to find a new way to present concrete as a precious material.
The lamp and the seat are solid concrete, while the table is cast around a loop of insulation material to make it lightweight enough for domestic use. It has a terrazzo bottom for additional strength.
Small, semi-circular grooves in the table's surface divide it into thirds. The piece can also be dismantled, so that the top can be placed on its side when not in use.

Based in Vilvoorde, Belgium, Sment was founded by Sablon ? who is also a practicing architect ? and Frederik Bogaerts...
