[Jewelry making - Article 00903] - [Orchid] Ammonite Polishing

    I found an imperfection in the cap on an ammonite doublet freeform
    and decided that I had nothing to loose, so I tried to polish it out.
    I was able to remove the imperfection using fine sand paper and
    tripoli polish. Unfortunately I ruined the "glossy" surface of the
    cap. If I wet the ammonite, it looks great, but as soon it dries out,
    the surface gets hazy and the iridescence of the ammonite does not
    come through. I tried to fix this with both red rouge and green
    rouge, but neither helped. 

    I always thought that these ammonites were capped with quartz or
    something similar, but the cap on this one seems more like a
    polymer/plastic.  When I was sanding and polishing, I smelled
    something like burnt plastic. 

    Can anyone suggest how I can clean this up and make this nice
    ammonite brilliant again?
