this is how..

for your information, there is no warranty card when you purchase your stuff here. however, to guarantee the authenticity of the pearls that you bought from me you could do one of these tests;

• try scratch your pearl with a coin and then using a soft cloth rub it, and the scratch should fade away,

or

• bite the pearl. if you could feel sand coming out from the pearl then it is original.

and, pat talcum powder once in a while to your pearls to ensure the longlasting of the blings.
