Talk about unique, this rare large Montana moss agate slab continental divide with dendrites and snow drifts and dark gray areas, some of which have a metallic looking sheen like hematite. This has a divided area with tightly banded dendrites near one side. The white snow drift swirls are super cool looking almost like a topographical map! The thick slab weighs 5.215 ozs and measures 5" x 3.5" with .252" to .262" thickness. This is part of a huge estate buy from a man who passed away in his late 80s and had his collection as well as his father's. He had tons of Montana which I wasn't too keen on so only purchased a few choice slabs and very few rough rocks, unfortunately. This is probably the best of the lot and gorgeous, as you can see.
