Petrified wood


What is petrified wood?
Petrified wood is fossilized wood, created by certain natural circumstances. Often after a volcanic eruption, when trees fell down and got buried under a thick layer of volcanic ash. After this began a process of replacing the organic materials by minerals, mostly a silicate like quartz.

Some of the petrified wood is perfectly preserved, you can still see the structure and the rings of the original tree. The beautiful colours depend on the minerals that were apparent during the fossilizing process.

Our Suar wood comes from different areas in Indonesia. We select the most beautiful slabs found in Java, Sumatra, Sulawesi and some smaller islands.

Why to choose for Suar wood table tops from Indosign?
We import the table tops directly from Indonesia. Only the best quality of well dried wood is selected. We only choose beautiful looking slabs with sizes that are suitable for use as a dinner table. Most suppliers offer tables from one piece with small cracks in the surface. The cracks are secured with wooden or metal plates. Our tops are cut from one piece without any holes or cracks in the wood.

We can even send pictures of (unfinished) slabs to choose from, before shipping to Europe (reservation of slabs possible before arrival).

Is the material allowed to be cut, and what about nature protection?
All our wood is permitted to be cut by the government (SVLK certification). It originates from areas where the trees were planted by people many years ago (not from protected tropical forest). The SVLK certification ensures that the wood is cut from legal places in Indonesia.

Is there a thought about Corporate Social Responsibility?
The areas where the wood is coming from are called the Plantation People Forests. About 50-70 years ago, the government started with the construction and plantation of these areas for the use of wood production. The wood from our tables are coming from these special areas and not from the protected tropical woods. After the harvesting, new trees are planted for production in the future.

How will the slabs be finished?
We usually finish the slabs with a protecting oil and wax treatment (after sanding). This gives a natural look to the table and maintenance of the table is easy.

Can you choose for different table legs?
The table tops will be delivered including standard designed legs (U-shape). Other legs are possible, or you can design your own model.



The Kauri is the biggest tree in New Zealand. The living Kauri-tree is protected and isn’t allowed to be cutted. The wood that we use for our tables is digged from former swamps and is 30.000 to 50.000 years old. No tree was cutted, which makes these tables very environmentally friendly.

How special is the Kauri-wood?
The Kauri-wood is the oldest and most exclusive wood in the world. The golden “flame” structure in the wood is unique and can’t be found in any other wooden table. Besides that, the supply of Kauri is finite. This means that the purchase of a Kauri-table can be seen as an investment, because your table becomes more valuable.

How does the production of a customized Kauri-table work?
The import of raw Kauri is forbidden. That’s why we customize our Kauri-tables and do not have a stock of Kauri-wood. Our production in New Zealand is experienced in the processing and finishing of Kauri-tables, which is not an ordinary job.

Before start we offer different types of available Kauri-slabs. When we agreed about the slab and the associated price, we start with the production of the table. By sending pictures or even a movie, we keep you updated about the process of production.

How are the table tops being finished?
Before the start of the production we discuss the preferred finishing. We let you choose from different options, each with it’s own appearance. You’ll get your customized table, exactly as you wish.
