"Nailhead" needed!

[oldminer]

I need on or more nailhead cut round diamonds for educating the Imagem devices to recognize their specific character and appearance. We have seen thousands of nicely cut stones, but only a couple accidental nailheads and fisheyes. A loan of a stone or two for a day would be highly appreciated.

I will pay shipping and insurance both ways, of course.

Thanks if you can assist/
