Mother of Pearl and Black Onyx Cufflinks

How come it is always the women who crave and appreciate the use of pearls? Is there an available accessory that will make men use them? A friend told me not to buy pearls if the wearer or user is just myself. She said that pearls are synonymous to tears. If the wearer buys pearls for herself then it will not bring him any good. Pearls are meant to be given as gifts. One is better off receiving them instead of buying them for personal consumption. Pearls signify good luck to the person receiving them. So to provide good luck to my brother, I am giving him a pair of black onyx cufflinks with mother of pearl.
