Yellow Sapphire (Pukhraj) Stone at Best Price, Natural Ceylon ... How much Carat/Ratti weight of Pukhraj should I wear? Ideally, One should wear minimum 1/12 of Body weight, like 1 Carat (1.1 Ratti) per 12 Kg. For e.g. If your body weight is 60 Kg, you should wear 5 Carat (5.50 Ratti) But, if person choose to go for high quality gemstone, even much lesser carat weight provide equally good results.
