These are copper (infused) replacement agates, the rarest agates to date! They were formed in the Kearsarge lode of basalt from the Kearsarge/Calumet Michigan area. They are only found in this lode!
To really understand these very rare and unique agates, a must read is an article by Dr. Wayne Sukow in the November 2011 issue of rock and gem magazine . It explains about the rare copper infused agates of the Kearsarge lode, found in just a few area mine dumps in upper michigan.
Dr. Sukow was also one of the main speakers at the 2012 International Agate show in Minneapolis in July. Those presentations are available for sale at the Minneapolis rock club website.
I got to meet up with Dr. Sukow, and it was a great pleasure to spend time with him discussing these very rare agates. Getting Dr. Sukow and Jack Hobart together at the agate show was a real treat for all!!!

note! unless otherwise specified, these specimens are from the Wolverine #2 mine dump, Kearsarge Lode, in the ooper of Michigan.
Is a nice Wolverine #2 copper infused agate half nodule from Kearsarge, Michigan.
It is a rarer type as it has two eyes of copper, one by the quartz area, and the second is up in the fine banded copper. There is several small areas of solid color chalcedony. I stopped at 600 grit grinding, leaving it up to the buyer to finish off for jewelry or leave it as is for the collector.
Item #B900, cost is $45
This is another rarer type copper infused agate that has a spot of silver in it as well. It is from the Wolverine #2 mine dump in Kearsarge, Michigan. This half nodule has a center of a semi translucent center with sprays of copper and a spot of silver in the center and a light gray mineral as well. Outside of the circle there is areas of white chalcedony, then a layer of pinkish agate, then more of a white color. There is also wisps of a green mineralization throughout the specimen which is set in its Kearsarge lode bedrock. This mine dumped has drastically been reduced in volume over the last 4 years. The supply is getting scarce of these rare infused agates. Total weight with lexan base is 23 grams. I stopped grinding at 600 grit, as I did not want to grind any silver off the specimen.
Item #B881, cost is $55
Is a nice half copper infused agate with silver from the Wolverine @ mine, Kearsarge, Michigan and collected in 2012. It is a rarer in color as it is a reddish color along with white chalcedony and sprays of copper. Usually a circle is consistent as an eye, but this is not an eye. In this circle is 3 small spots of native silver. Finding a spot of silver in one of these copper agates is about on the ratio of one in every 2000-3000. I have only found silver in those specimens I found from 2012/2013. Outside of the circle is more sprays of copper in a green mineralization and white chalcedony. A rarer type of copper infused agate that is mounted on a clear plastic base. It weighs in at 7 grams including the base. I stopped my grinding at 600 grit, as I did not want to lose any of the silver in the circle.
This mine dumped has drastically been reduced in volume over the last 4 years. The supply is getting scarce of these rare infused agates.
Item #B887, cost is $70
Is a very unusual copper agate as it has 3 distinct eyes. The two smaller eyes have copper banding along with green mineralization bands. The larger third eye has no copper. The outer rim of the nodule is solid non banded agate or chalcedony. The half that has the large eye is all non-banded agate, while the other half with the two smaller eyes is banded. The pair weighs in at 5 grams.
Item #B453, cost is $50
This pair shows the distinct difference, one side is quartz the other is banded agate with areas of copper in them. notice the copper also rim's the majority of the outer surface of the quartz. They weigh in at 6 grams.
Item #B325, cost is $45
This a rare pair of Wolverine #2 copper infused agate that also contains a spot of silver. The spot of silver is only in one half of the larger agate. I stopped grinding around 1200 grit to preserve the silver. Finding any silver in a copper agate is like hitting the jackpot! This pair is still in the Kearsarge basalt and found in 2013. There also another half of another but smaller copper agate. This half is also unusual as it has a cavity in the agate banding. There is micro red crystals in the vug, and a larger dull green on top of the red micro crystals. I cannot tell if it is a spot of copper or a green mineral associated with this lode. This grouping in matrix weighs in at 10 grams.
I find a copper agate that also contains a spot of silver in about one out of 3000 cut and checked copper agates.
Item #B2, cost is $70
A single piece of a copper agate that has a separate eye on each side of it. the side showing has an eye of both white agate and creme color agate.

The other side eye is smaller but with more of the purple coloring it, and agate in several areas. There is a green mineral in the center of this eye. A very unusual piece combing agate, copper, agate and other mineralization's in it. This piece has two separate eyes.
Item# B327 Cost $75
I am putting this specimen in both the copper agates and the datolite listings.
One half looks to be part white datolite and the remainder is quartz which has a amethystine color to it. There is a couple of fine fixed fracture lines with red and green in color. The other patina is half white and has the datolite look to it. It could also be some very white chalcedony, but have not seen any this white. Datolite is rarely found at the wolverine #2. It weighs in at 3 grams.

There is a bit of amethystine color on the one half. The bottom third of the set is non banded agate, and has a nice round area of copper in it. The one half has a top that looks like the top of a hersheys kiss. A nice set for jewelry or the specimen collector. The pair weighs in at 8 grams.
Item #B5, cost is $25
This is a great micro specimen of a wolverine #2 copper agate. The bottom part of the nodule is a quartz ball. Next to the quartz is another smaller section of quartz with two bands of agate in it. The quartz is outlined with thin bands of chalcedony that as it nears one end it splits into a Y. The other third of the specimen is divided by an eye of agate surrounded by quartz with sprays of copper in it. The banded agate continues around all of that section. Quite a bit going on in this specimen that weighs in at 5 grams.
Note* This pair was ground only up to 220, as I leave it up to the buyer to decide to keep as is or to have finished out. The copper in all the sections look to go pretty deep into each section.

Item #B340 Cost $25 on hold
This lot consists of one half of a copper agate, and one half of another copper agates. The larger piece is a paint agate found at the bottom of the wolverine #2 pile. One half of it has a dark green eye with bands of white, pink and green bands. What makes this a strange agate is that the bands start out as pink then change to greens. The halves are separated by a green mineral line. That is copper also showing up in the darker green area on top. I was only ground to 220 as I was afraid to lose any copper in the darker green area.
The other half is a dark green crystal with a nice spray of copper in it. This half has a bubble of pink expanding into it from the rim. The pink color goes completely around the specimen. It has not been given a final polish only ground up to 600 grit. you can see some rough spots on it yet. This weighs less than a gram.
The second specimen has an eye with a white agate or quartz center rimmed with copper, then a nice wide band of white chalcedony . It then has very fine bands of copper mixed clear crystal with a purple hue, and white chalcedony . It also has copper going around the outside of the majority of the sample. This specimen weighs less than a gram.
This lot is a great addition for the micro mount collectors.
Lot #B351 Cost $50 sold
A very nice paired paint agates with specs of copper. The color combination is great with pinks, whites, greens, purple, and creme. Trying to focus in on all the different agate eyes was rough, but still the pictures do not give it justice. The multiple banding of various colors makes this a micro collectors dream. There is flexs of copper in both halves. The smaller half picture #3 weighs 1 gram, the last picture of the larger piece weighs 3 grams. Another nice pair from Kearsarge Michigan. Note: there are still some minor saw marks on the faces, but the collector did not want to go down any deeper on the face.
