This stromatolite fossil slab is 4.5 inches x 2.25 inches x 1/4 inch at shortest points and is super nice quality. It is shown dry only with front and back of the slab shown. It seems to be an agatized version. It would make really nice cabochons or the slab could also be used as a display as it is a rarer material. The Utah Picasso marble slab is 3 inches x 2.25 inches x 1/4 inch at shortest points and is also super high quality. It is shown dry only as well. Both slabs are pretty much polished already!
Both slabs were cut by our Shop using a really nice diamond blade saw. The stromatolite rock the slab was cut from was purchased from a really old timer's collection at an estate sale.
