You ask the gemcutter to appraise the contents of a dark spidersilk backpack.
The gemcutter takes the spidersilk backpack and inspects the contents carefully before saying, "There are 58 items that I do not deal with at all. I found one piece of jewelry that I do not buy in container deals. I did find 17 gems that I'll give you 115637 silver for, if you want to sell."
The gemcutter then returns a dark spidersilk backpack to you.

That was a good 15 minutes work.
