Don't buy jpearl silver or gold coins/bars

Don’t purchase jpearl gold and silver coins or bars it’s my honest review. There is no doubt on its purity its pure as it claims by brand but problem is with its weight, if you purchase 5 gram silver coin then you will get roughly 4.92 gram silver coin and if you purchase 2 gram gold bar then you will get roughly 1.94 to 1.96 gram of gold. This brand protect it with its standard weight policy which is (+ or – 20mg weight torrence)

Before 1 week sold my some gold to  jewellers which included gold from rsbl, bangalore refinery, tbz and jpearl brand gold, and I did not find any weight problem with gold except jpearl gold coin all were having less weight, and I lost money in total of 0.3 gram money which is roughly Rs.1200
Below is the weight of 2 gram jpearl gold bar which is till present with me. How its possible to get less weight evertime? Same issue I found in silver coins also were all coins have less weight.
