How to prepare a large piece of Arizona jasper for display?

0 votes

Hello,  I recently stumbled upon a large chunk (~50lbs) of Arizona yellow/red banded jasper.  The face I'd like to display is rough and has some deep crevices.  It's not going to be feasible to polish this one.   I'm considering a couple of options to improve the color when it's displayed inside:  mineral oil, silicone spray, or the Home Depot approach which would be a commercial stone penetrating sealer/enhancer.  I'm concerned about the tendency of mineral oil to attract dust, but it seems like the lowest-impact approach. Any recommendations for product and method of application?   It's a big hunk of rock, so dipping it in a solution might get expensive...   Thanks in advance.

In general, luster enhancements are discouraged by many in the mineral community, but its done anyways in a lot of cases. Different material respond differently to various lubricants, and those who do this repeatedly know what words best. I have heard of mineral oil and silicon sprays used to enhance luster.
