Float COPPER is Amazing Sometimes

An amazing Float Copper Cabochon, with a perfect Quartz Crystal inside, inspired me to wrap up a great pendant. This pendant is named “Float Copper Marvel”.

Quite a few years back, at the Tucson Gem & Mineral shows, I, as usual, checked in with my friend Ken Flood. Ken owns Keweenaw Gem & Gifts in Houghton. We go back a long way, and he knows I enjoy making jewelry from the rare and unusual Rocks & Minerals from the Keweenaw Peninsula.

Ken sells multiple Keweenaw products that his business manufactures. Ken said he had something special for me to look at. He produced a quantity of Float Copper Cabochons with beautiful Quartz inclusions. I have never seen such unusual Float Copper. He has a special wire saw that he uses to cut Float Copper. You need this special saw, as pure Copper really gums up the normal Lapidary saws. Normal Lapidary saw blades produce so much heat they tend to warp.

Usually Float Copper pure native copper, but in these special pieces it contained Quartz; some gorgeous Crystals. It was a surprise when to find this Quartz in the copper.

For those that do not know, Float Copper is copper that was ripped from copper-bearing basalt by the Glaciers thousand of years ago, then transported in the glacial till (floated) and deposited in other locations, usually not far from the source.

From many years ago–my buddy Chris Cooper. I told Chris to check a newly logged property in the Keweenaw for Float Copper. Chris headed out and within 10 minutes I heard a “YELP”! He came out and lo and behold, his first piece of “Float”
Here is Chris’ Keweenaw treasure all cleaned up.
The world record, 19 ton piece of Float Copper at the AE Seaman Mineral Museum.

Today, diligent searching with metal detectors, sometimes yields these transported pieces of copper. Smaller chunks are normally sold as specimens to rockhounds. Sometimes the Float Copper is very massive in size. The official Guinness World Record Float Copper specimen is 19 tons and resides at the AE Seaman Mineral museum (Michigan’s Official stare Mineral Museum) on the campus of Michigan Tech in Houghton.

Quartz Garden Pendant-Quartz Crystals in Float Copper.

I have wire wrapped a couple of the cabs I acquired from Ken. One has a group of Quartz Crystals we call “Quartz Garden”, and one has a beautiful single Quartz Crystal. Completion of this pair or pendants has been a long time coming. I’m so pleased with these.
