The image of an exotic luxury swimming pool is now becoming synonymous with that beautiful turquoise-green lining the bottom. This colour is the product of the rare and highly coveted stone called green sukabumi.
One of the reasons this stone is now so popular, is that the green colour is completely natural. So, how are green sukabumi tiles actually made?
The natural process
Starting life as humble sandstone, green sukabumi is a type of quartzite that becomes green due to the types of particles in the environment when it is formed. Only found in Indonesia, the natural stone was originally discovered in the Sukabumi regency of West Java – hence the name.
In its rawest form, green sukabumi is comprised of sandstone and the mineral quartz. The stone forms when sandstone and quartz together are subjected to high pressure or high temperatures. When this happens, they go through the process of metamorphosis – that is, they change form. The sandstone and quartz particles fuse together to create quartzite – a hard rock, which is often made up of at least 90 per cent quartz. During the metamorphosis process, other particles in the natural environment are also subjected to the pressure and temperature, and so become part of the newly formed quartzite. These additional particles are what create a range of coloured quartz products found in shops around the world. In the case of green sukabumi stone, the particles that happen to be present create the green colour. The variation of particles present during metamorphosis are what makes every sukabumi tile a unique shade of green.
On its journey from Indonesian boulders to your pool deck or floor tiles, green sukabumi undergoes a series of transformations to become the product you eventually purchase. Large blocks are cut into more manageable sizes by head or gang saws and are eventually sliced down to individual tiles. They are honed by hand to ensure minimal variance between each batch and checked individually to ensure shape and depth consistency. The tiles are then shipped from Indonesia.
