Small concepts you need to know; it is very important to know, at all times, what you are buying. Is it wrong to buy a synthetic diamond?  NO, provided the seller says IT IS A SYNTHETIC DIAMOND. This means it will be cheaper and that both the buyer and seller are on equal terms,and the buyer won´t feel cheated.

Lead glass is easily damaged, so it requires special care and handling, because any damage is irreversible.If the buyer knows all of this and still decides to buy the ruby, then the transaction is completely ethical.
