This exclusive jewellery manufacturing process exploits the difference between lava and gold melting points, as gold fuses at 1.000 degrees while lava at around 1.300 degrees Celsius. During this process fused gold, whose pressure exceeds 40 kg per each gram of gold, is injected by centrifugal force into the lava rocks. Since the lava melting point is 300degrees higher than gold, it is able to withstand the impact of this fused metal. So the molecular structure of red hot lava that has reached one thousand degrees Celsius remains untouched and encapsulated in the melted metal that fills the cavities of the stones.
