muheani, there's a place huko garissa lodge, its actually a hall full of walalo women trading gold, buy sell.. edit your gold items kila kitu, they are very honest, just try cross them though, that is IT for you. I cant remember the name of the building but if you ask the gold place/hall you shall be directed.
PS: Not been there, just been told about it by a pal.
