"Used clear acrylic fixative spray on the half piece because I'm afraid of the orange material drying out, going opaque and flaking. I had that happen to another egg with a similar material inside"
Yea that could be a problem if you are cutting a cab. Do you have any idea why that happened? How long did it take? I have no idea of what kind of offer to make you for the slaps. And they are not really for sale at this time.
"Hey, if you're serious let me know what the average going price for uncut or cut eggs like this might be. I have asked my boss about selling material (I work for the nonprofit that owns the land this egg came from. We sell old pipe fittings on ebay. why not rocks?) but he's skeptical that there is a viable market. If I can take him info that yes, something like this would sell and bring in funds for summer scholarships or maintenance or something it's a lot more likely it'll become available sometime in the future"
OK so I am not sure of the exact size.
Do you think a donation of 5$ per slab plus postage would be fair? I would be willing to cut the best cab I see in the material and enter in the contest. You have posted so many pics of cool stones that I cant help thinking about a cab out of it. Here in Southern Indiana you just dont find rocks they have to be imported
