My parents bought me necklace haaram set weighed 144 grams 10 years back, i didn’t like the design of that, am not wearing it for any functions, now i don’t have much options to wear for any functions, i want to purchase new set but considering the gold rate that seems like a long road, but if i exchange am going to lose a lot wrt wastage, any advise what should i do and how much i might loose ?
