Blue Light Refraction

Blue Light Refraction

By /September 21, 2023 /2 comments /Cut Rocks

Rock #5258Light refraction causes electric blue agate I have never seen anything quite like this before from The Carver Agate Field.  The presence of the sagenitic growth seen in this specimen no doubt is largely responsible for the electric blue color.  While the sagenitic golden material obviously is not blue, I believe that it captures certain wave lengths of light that enter the stone, while in this case leaving the blue light wave lengths to refract back out of the stone and make it appear deep blue.  The refraction of light by the internal characteristics of a stone is not unusual—think of diamonds and opals.  On page 27 of his book Gemstones of the World, 1977, Walter Schumann explains as follows: “color is produced by light;  light is electromagnetic vibrations at certain wave lengths.  This visible light falls into six parts, each of a particular color (the spectral colors: red, orange, […]

Summer Harvest from The Carver Agate Field: 15 Stones

Summer Harvest from The Carver Agate Field: 15 Stones

By /September 1, 2023 /2 comments /Cut Rocks

These beauties show the wonderful and unique geological agate varieties I have been fortunate to ‘happen upon’. This variety is illustrated, once again, by these 15 different stones which I cut in August, while not needing to tend my garden or mow grass. These stones were particularly fun for me because I hit a hot streak of remarkably interesting stones while simultaneously cutting rough material with two separate diamond saws. These beauties seem to appear one after another (sure, I have lots that I cut that go to the reject pile for many various reasons). But, my August work had very little rejected material and kept me busy doing what I really like to do—making stones shiny. Here are the results of my August harvest. To get started: Both of the stones below, #5208 and #5215, were cut from the same piece of rough. Eye popping beauty or just interesting? […]

More Brand New Geodes from The Carver Agate Field and My Bullwheel

More Brand New Geodes from The Carver Agate Field and My Bullwheel

By /July 28, 2023 /4 comments /Cut Rocks

Through the winter, I have cut many geodes and other cool stuff. You have seen many of the cabs that I have cut and polished but the geodes, while cut open, have not been yet been published here yet. This is because the cabs are small enough to process on my Cabking, but the geodes are in many cases too large for processing and polishing except on my Bullwheel. The Bullwheel Because of the larger size of the geodes, they do not easily polish well on the Cabking, which only has a 2-inch wide polishing surface. The Bullwheel (see photo above) has a 4-inch wide abrasive belt which is much better for the larger specimens. The Bullwheel takes interchangeable 4-inch wide belts in 80, 100, 220, 320, 400, and 600 grits. The polishing of the larger specimens occurs utilizing increasingly finer grits, beginning with 80 and ending with 600 grit. […]

Paisley Agate?

By /June 28, 2023 /1 comment /Cut Rocks

The winter storms tree damage is all cleaned up, processed to saw logs and split firewood. Three large fires that I lit burned up all the brush. So, I had a bit of time to cut and polish more of The Carver agates. Rock #5171 : Paisley AgateI found it, cut it, and named it The paisley agate was named by me. It is a bit dark for inclusion in jewelry, but I liked it because the pattern reminded me of the paisley so popular in my childhood. Rock #5161 Photo 5161 is a heel grind of a small agate nodule which yielded ‘sunflowers’ in a pretty blue-appearing stone. The blue color of the stone was enhanced greatly from a pale white to the blue that you see due to my photographing the stone on a very foggy Maine day. When photographed in my shop on a sunny day, the […]

7 Totally Different Agate Specimens

7 Totally Different Agate Specimens

By /January 24, 2023 /0 comments /Cut Rocks

My last blog posting highlighted cabs I cut in January, 2023. The purpose of these postings is to highlight the incredible variability of material from The Carver. This posting shows actual specimens rather than cabs. Enjoy! Rock #4963: Agate Geode Rock #4958 : Carnelian Fortification Agate Rock #4975 : Agate Geode Rock #4948 : Geode with Fortification Agate Rock #4960 : Geode with Crystalline Center Rock #4949 : Fortification Agate Rock #4961 : Fortification Agate, with yellow-orange dots creating the color

Season’s Greetings with a Red Ribboned Geode!

Season’s Greetings with a Red Ribboned Geode!

By /December 16, 2022 /1 comment /Cut Rocks

A striking new geode and cab is cut as The Carver Gallery and Shop reopens after a two and a half month hiatus during home renovations! Well, that explains why you have not heard from me in a while. Now back in business, the geode and the cab cut from the geode display brilliant red ribbons around the crystal lined geode pocket. If that is not cool enough, how about the sky blue between the dual red ribbons! Red ribbons wrap the “Christmas geode’s” sky blue center surrounding the crystal lined pocket Seems “Merry Christmasy” and a harbinger for a Happy New Year for me and, hopefully, you all as well.

Crystal Oddity Encapsulated in a Blue Fortification Agate

Crystal Oddity Encapsulated in a Blue Fortification Agate

By /October 7, 2022 /1 comment /Cut Rocks

This is a cross section of a blue agate nodule from The Carver Agate Field. Rock #4914 The small nodule, approximately 2 inches across, was initially cut and lightly shaped to capture the fortification agate in the center of the stone, as well as the ‘white eye’ on the left-hand side of the stone. And for even more interest, there was a contrasting brown spot on the upper right-hand part of the stone. That explains why I was cutting this stone in the way it was cut. Rock #4914 magnified Well, once cut and polished and subjected to modest magnification, the brown spot suddenly and unexpectedly became the highlight of the stone and the subject of this blog. Magnification, as shown above, produced a highly angular brown crystalline structure and not shards of broken or fragmented stone encased later in the agate. When this agate nodule formed inside of a […]

The most interesting of the five stones is the “ghost,” shown below in two different angles. Click each image to see an enlarged version. Rock #4910 Rock #4909 Next we have a yellow fortification agate in an “octopus garden beneath the sea.” Rock #4894       Photo 4906 below is the slab from another nodule creating a cut and polished agate which looked blue before being cut and more red to orange after being fully polished.      Rock #4906 Rock #4906 close-up Photo 4896 is a jasper/agate free form designer cab. I just liked the colors.     Rock #4896 For the lapidists out there, photo 4899 below, which I call the flower garden agate. is the most interesting cut that I have done in a while. Usually I take a nodule, cut a thin slab from a crosscut of the nodule, and then grind and polish, as is the case in all […]

Yellow Fortification Agate Geode Cabochon

Yellow Fortification Agate Geode Cabochon

By /September 25, 2022 /2 comments /Cut Rocks

Rock #4876Click to enlarge This is a beautiful cab cut from a cross cut slab from a Carver geode. The crystal-lined geode center sparkles in the center of the yellow fortification agate. The sagenitic material (green and brown stuff) along the top edge of the stone indicates that this was the bottom of the geode when formed in a lava gas pocket. The sagenitic material likely fell off the inside top of the gas bubble pocket to the bottom of the gas bubble pocket where it was encapsulated by bluish agate (silica) as it filled the gas bubble pocket. See photo 4877 below which is the same stone photographed with the sagenitic material on the bottom of the stone as it would have been formed. Rock #4877Click to enlarge

Lava Breccia in Agate Matrix

What a unique and interesting cab! Close-up shows lava shard at top centerClick on the image to view an enlarged version Another cab from the same stoneNote the same lava shard (top center) These two cabochons were cut from a single stone. The lava shard (top center in both stones) shows their common origin. Above is another agate breccia with banded agate (top and lower right shards) with a lava shard in the lower center of the stone. Note the eye agate on the left center edge of the cut stone. While this stone is not pretty, it sure is interesting—at least to an old rocker like me.
