Trimming Linwood barite specimens before/after

Those of you who haven't seen this yet on Facebook, I thought I'd share the anatomy of a trim job on some Linwood Mine Iowa Barite. First photo shows complete plate with keys for scale. second photo shows plate ready to be trimmed. Last photo shows first specimen cut off and put back to where it started at. The following reply will have the completed specimen photo.

I use a diamond cut off saw (gas) to dismantle the pieces, then work with micro abrasion tools and pen type engraving tools to remove saw marks and other unwanted parts of the specimens.

The total prep time on this beaut was about 6 hours total. The removal of saw marks and cleaning up any unwanted areas is where the time adds up in a hurry. Any and all of the straight lines have been removed, and made to look more natural. Who knew Iowa could produce such beauty!

So I have be collecting at the In rte 37 road cut N of Bloomington where the great aragonites were found some years ago. Did you know that the I 69 construction crews are completely leveling the cut? It will be an extinct site within just the next few weeks!
If you are interested, these next few weeks will be your swan song opportunity to collect there.
Found several interesting examples, but no great specimens. One will be in my display case at this coming weekend's Bedford/Lawrence County Club show at the Lawrence Co fairgrounds (formerly the Bloomington show). Will you be down? BOB
