Dear all

    This could be an interesting subject which it's issue has hit in the
    face and no mater of the years I've under my belt I feel like Georg
    Forman in Zaire, don't know what hit me. 

    We are a wholesale company which its product (18 k white gold/
    Rhodium plated), after being with the retailer for few weeks, has
    some darkening problem (it's loosing its luster). We went over with
    our factory on all the steps taken by them to produce our product. 

    Now........... Our product has good percentage of pave-setting with
    stones vary form half point to 1 point! What I'm trying to indicate
    is that there are a lot of prongs, dummy prong and mill grain, which
    will create cavities that might work as dust storage!!! That's one;
    if that was the case you will think that a little bit of bzzzzzzzzzzz
    in the ultrasonic & steaming the heck out of it will do the job. "Not
    on most of the time" 

    Trust me when I say that I'm bringing the factory on its knees to
    tackle this issue but I feel there is something more in it than your
    usual suspects that cause such a problem. 

    Well........ I had to do it the technological/ scientific/ logical
    approach!! I called a company called Red Sky plating
    http://www.redskyplating.com/index.htm and I spoke to a gentleman
    called Neil (if my memory helps here) and the man spoke of knowledge.
    He said most likely my problem is caused by bleeding in/out. In
    English!! Means that the metal is acting as a sponge and absorbing
    some acid, which stays (the acid) in the metal's cavity, porosity,
    surface, so after producing the goods and after passing some serious
    QC eyes, I mean serious, it leaves toward our retailers. 

    Then because the heat generated by the display cases bulbs and the
    trapped atmosphere; it starts to bleeding out (the bloody acid)
    which will create a recipe for disaster and starts to contaminate the
    surface of the jewelry piece and resulting of darkening look(no
    luster) 

    Please don't be shy of throwing couple of your pennies in here, any
    knowledge, explanations, scientific theories, magical spells, funny
    jokes will all be very welcomed, hence I'm about to quit jewelry and
    work as a bartender "wishful thinking". 

Thanks for listening.
