Re: I need help identifying my specimen

The great thing about lakers is they come in all sizes, shapes and colors. I would say more than likely this is a Lake Superior agate. I have not heard of or seen any other type of agate found anywhere in Minnesota. The whitish coloring on this appears to be what some refer to as "opalizing". Not sure if it's an actual term and it's definitely not real opal, but from what I gather it's a bleaching of the natural color of the agate either from the sun or a chemical reaction. I have found several that have this "opalizing" on one side and the natural colors on the other. There are also Lake Superior moss agates that have an infinite array of colors, patterns and inclusions that look nothing like the obvious fortification agates.
