Carnelian Agate and Sheaves of Wheat

Carnelian Agate and Sheaves of Wheat

Rock # 5370This carnelian agate is a likely candidate for a newly designed piece of jewelry. Rock #5364 Rock # 5364 This reminds me of sheaves of wheat and, when enlarged, shows hollow shaft-like crystals surrounded by agate swirls. While the ‘sheaves of wheat’ in this stone are interesting, they do not make this stone a candidate for jewelry. Rock # 5365What was the formative process that made this ‘mess’? Rock #5373This caught my eye because it is not visually similar to the other ‘stuff’ that I found on The Carver. I don’t know what it is but it is an interesting outlier. Rock #5379 Use your imagination! Isn’t agate great!? Rock #5369 Agate in basalt matrix. Rock #5374This is another cab from the agate in basalt matrix as seen in photo of Rock #5369. This stone looks ‘post-apocalyptic’! I love finding and highlighting the obscurities found in The Carver […]

Unusual black chalcedony geode and other anomalies

Unusual black chalcedony geode and other anomalies

This is only the second black geode I have encountered on The Carver. This is dense black chalcedony, not basalt. Other photographs shown here are of the cabs which I cut from this black geode. Rock #5343I have never before encountered pitch black chalcedony in a Carver geode. Chalcedony is a micro-crystalline quartz (silica) common in many agates. It can be many colors but is most often translucent or transparent. Pitch black coloration is, from my experience, very rare. Click on the images below to view enlarged versions of this examples. Rock #5336 Rock #5248 Rock #5241 One stone yielded a slab that I turned into this fancy-cut designer free form cab (Rock #5325), as well as stone #5258 below. Rock #5325 Rock #5258 Last but not least. . . This small flat-topped cab features a crystal filled vug and the ‘fill tube’ (term likely not geologically correct) all from […]

Blue Light Refraction

Blue Light Refraction

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, […]

Paisley Agate?

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 […]

Five Hot Memorial Day Freeform Cabochons

Five Hot Memorial Day Freeform Cabochons

While I have been busy getting my garden in and cleaning up the disaster from the last storm that took down over 12 trees, I squeezed in enough time for five distinctly different but super interesting designer freeform cabochons. Cab #5136: Crystal lined dendritic agate geode Cab #5150: Brecciated sunset agate in lava shards Cab #5150: Note the lava shard below the sunset Cab #5141: Crystal filled agate geode—may be in my next bracelet! Cab #5148: Teardrop flower garden agate. I love the shape and pattern of this stone. Rock #5144: An immensely complex agate. See close up below. 5144: Check out the colors, patterns and the very cool ‘blob’ nearly surrounded by the white area of the stone. This stuff really fascinates me. Hope you enjoy it. And have a safe and enjoyable Memorial Day Weekend, too! PS. This is the clean-up project I was working on after a […]

Carver Agate Field Variety, January 2023

Carver Agate Field Variety, January 2023

January in Maine is about keeping the wood stove full, dealing with ice and snow, and best of all, some time to cut and polish remarkably varied colors and types of agates, geodes, and jaspers that continue to come from The Carver Agate Field in Alpine, TX. As a group, these 11 cabochons (cabs), as well as the 7 rock specimens which will appear in the next blog posting, again tell the tale. Individually there are several quite unique and interesting stones for the rock enthusiast. I would recommend you view these specimens as large as possible. You can open each image and enlarge it by clicking on it. Rock # 4972 : Slab from a geode! Notice a portion of the crystal lined geode pocket at lower left side of stone. Rock #4951 : Carnelian (red quartz) fortification agate cab Rock #4937 : I suggest you enlarge this photo […]

Yellow Fortification Agate Geode Cabochon

Yellow Fortification Agate Geode Cabochon

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

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.

Two Completely Different Triangular Free-form Cabs from The Carver

Two Completely Different Triangular Free-form Cabs from The Carver

These stones are all Carver agates, but completely dissimilar in their appearance. The First Stone The first stone looks like a deep blue underwater scene with multicolored sagenitic (cool stuff!) that look like underwater plants in an undersea cavern. Put your imagination to work and, if you are old like me, think of Lloyd Bridges and Sea Hunt! Rock # 4727 Click to enlarge Rock # 4727 detail Click to enlarge More Stones The next two stones are blue and white banded agate, one of which is a pyramidal free-form. While I have recently cut several other stones, I like these best. Rock #4711 Click to enlarge Rock #4711 Click to enlarge Rock #4713 Click to enlarge
