Deep boiling diamonds is a process whose aim is to remove, distance, metabolize and whiten dark stains that are found in the stones and which have access to an external facet. Deep boiling metabolizes the filling material, as well, and returns the stone to its pre-filling state. This action is not considered a treatment and does not need to be reported.

Steps in the Process

In the deep boiling process, the diamond is inserted into a special tool made of the element tantalum and containing special acid. Tantalum is a grey-blue colored metal that is especially resistant to corrosion and conducts electricity and heat very well. The process itself takes place at temperatures of 300 degrees Celsius, using pressure, and can last an entire night.
