Jaspilite Rough
Jaspilite is a local name for banded hematite and jasper that is found throughout the iron districts of
Michigan's Upper Peninsula. The hematite appears as a shiny metallic mineral while the jasper comes in a variety of
colors including red, yellow, black, white, brown, and maroon. I can supply wholesale quantites of this material as
both mineral specimens and cutting rough. All photos taken of wet material.

Nice piece from the Groveland Mine in Randville, Mi with oolitic jasper on a hematite backing. This material may
undercut where the hematite is and I don't suggest cutting this if you're a beginner, but it makes some very, very remarkable
cabs! Approx. size: 4"X3¾"X1½" Approx. weight: 1lb 10 ozs.

Top notch piece of oolitic material. The banded rough looks better, but I personally think the oolitic material
makes better cabochons. Approx. size: 8½"x5"x4¾" Weight: 13.4 lbs.

It's hard to see that this is some choice rough becuase the outside has been pretty weathered. This was actually
collected at the famous Jasper Knob in Ishpeming, Mi. Collecting is no longer allowed there and I was lucky enough to
acquire several pieces from there that were collected back in the 1950s. This is a great chance to own some rough from
this classic, now closed, location! Approx. size: 4½"x4¼"x2¾" Weight: 3lbs. 10ozs.

the day before heading home. Here's one of those pieces. Approx. size: 6½"x4¾"x2¾" Weight: 4lbs. 12oz.

The jasper is quite a bit darker on this piece, more maroon than red, but the hematite honestly, looks a lot sparklier.
I had a small piece like this before that I collected in the same area around Ishpeming, Mi. and I polished a window onto
side. I sold it right away, otherwise I'd put up a link to show you how cool this looks when polished. Approx.
size: 5¾"x3"x2½" Weight: 4lb. 1oz.
