Our NATTS Process is a highly effective deep-cleaning technique used to remove stubborn impurities, black spots, organic residues, and surface stains from diamonds restoring maximum shine, brilliance, and purity.
This process is widely used in the diamond manufacturing & trading industry for both rough and polished diamonds.
What is the NATTS Process?
NATTS is a specialized acid boiling treatment that uses a controlled mixture of strong acids under high temperature and pressure conditions.
It is designed to remove:
Graphite inclusions on the surface
Black impurities
Organic or chemical residues
Polishing compounds
Oil, dirt, and dust accumulated during cutting
It improves the appearance of the diamond without altering its natural structure.
