I have a strand of pink pearls I need cleaned and appraised

Oops

Im interesting for. The pistol colt MK-II Double Eagle serie 90 caliber 45

This place sells rare and *very* expensive firearms - along with reasonably priced ones. I am sure they deal with pearl inlays in 6-figure price pistols, but they don't do jewelry

You need a real jewelry store. This is actually a Firearms Museum.

I'm not sure if this is the place to have your Pearl's cleaned and appraised. It's a store for fireArms. But I could be wrong.
