to cut or crack?
June 15, 2012 04:14PM
I have found a nice specimen from cobalt,ON that has a calcite vien with some wire silver. The specimen is long piece of diabase with about an inch of vien on the end. If I saw through the diabase, the specimen will sit up nicely for display. The diabase is too large and some of it must go. My question is will the sawed base devalue the piece? Should I be cracking the bottom off instead. My concern about cracking is that it may not crack nicely or the vibration may crack off some of the vien. Crack vs Cut? any advice is appreciated

In my opinion as long as you are not cutting the vein to expose the silver but just trimming matrix it should not affect the value of the sample. What you might try is to cut part way through the base from the back and then crack the diabase off along the cut ( just put a tight fitting chisel in the cut and give it a tap, or better yet use a slitter to split it along the cut if you have one). That way it will not look cut from the front.
