half drilled, & necklaces. If the pearls are studded
on jewelry and convenient to test then we test pearls

Identification of different types of treatment on the pearls can be detected at our lab on piece to piece basis. Treatments like bleaching and polishing are normally accepted by the trade but, treatments like dyeing, luster enhancement (maisuri), lacre coating (pinkening) need to be disclosed to maintain fair business practise. Anyone interested in getting this detailed certificate has to submit loose pieces. The pearls have to undergo different machines for the result to come. For identification of treatment, the pearls have to pass through destructive and non destructive series of tests and thus has to be performed individually for every piece.
