Five Random Carver Agates

Five Random Carver Agates

Here are five random Carver agates I cut this week! One is the first one I’ve seen! These are five of the six agates I cut this week. The sixth stone will be the subject of my next blog. It is so cool and unusual. Detail of Rock #4681 – Click to enlarge Rock #4679 – Click to enlarge Rock #4685 – Click to enlarge Rock #4683 – Click to enlarge Rock #4687 – Click to enlarge Being lucky enough to cut five totally different agate types in a single week is a ‘rock hound’ fantasy! And why I never get bored as I continue to explore the amazing diversity of the Carver Agate Field agates. The highly variable colors, patterns, banding, and sagenitic inclusions make these just pure fun. Rock #4685 is another ‘first’ for me: white matrix with multiple colored sagenitic inclusions. I wish I had 50 pounds […]

My Birthday Agates!

My Birthday Agates!

These stones are maybe the prettiest agates I have cut. Or, they just seem like the prettiest because I just cut them! Both show clear evidence of red and yellow jasper that was fractured into shards and then cemented back together by silica which entered into the cracks. When the silica enters the cracks, it creates tiny fortification agates and other banded agates, e.g., a jasp-agate. I think the patterns created are simply beautiful. The free form shapes of these stones are the result of trying to capture all of the detail and coloration that is present. If I had cut the stones in the more conventional round or oval cabochon shape, much of the stones’ patterns and coloration would have been lost. Rock #4643 Rock #4645

The Lava Lamp in The Ghost

The Lava Lamp in The Ghost

This stone simply contains lots of cool stuff, particularly when enlarged or magnified. The unenlarged photograph shows a pale whitish ghost-like structure up through which a lava lamp-shaped log arises. Rock #4186 : Click to enlarge If you don’t think that is cool enough, take a look at the enlarged photos of the bottom center and bottom right of the stone. The bottom right of the stone as shown enlarged is a botryoidal structure, which is defined as having the appearance of a bunch of grapes. Bottom Right of Rock #4186 : Click to enlarge The other enlarged photo shows the botryoidal structure being cut open and appearing to have a somewhat hollow center. Bottom Center of Rock #4186 : Click to enlarge Later, I will be doing a more detailed examination of botryoidal agates, with more photos and discussion as to how I believe they are formed. Rock #4569 […]

Carver Agate Field Cabachons: New Video

Carver Agate Field Cabachons: New Video

I have been cutting more agates from The Carver. A few are cool enough to make me “make them shiny”! I have made a short video of some of the new cabs and hope you like it. Examples Be sure to click on each one to see the larger version! Rock #4629 Rock #4618 Rock #4616 Rock #4626

Zipper Geode (I found it, I named it!)

Zipper Geode (I found it, I named it!)

This is one half of a fractured geode which shows a much earlier fracture that was healed by quartz crystals filling the earlier fracture. While it is very common to find geodes with fractures that are filled (or healed) by secondary deposition of silica in the crack (fracture), it is quite unusual to find that the secondary deposition results in macro crystalline (visible to the eye) quartz crystals extruded from the crack. To me it looks like a crystal quartz zipper! Rock #3998

Banded Agate Mimics Banded Jasper

Banded Agate Mimics Banded Jasper

Until magnification, each of these banded agates appear to be comprised of the red and yellow jaspers which are so common on The Carver agate field. Magnification (see third photo), however, reveals that these bands are micro crystalline (too small to be seen by the eye alone), e.g., like agate banding. Unlike most of The Carver agates, these agates were not formed in a nodule or geode. My best guess is that they were formed as a vein agate in a crack in lava.

Lava Lamp Agate

Lava Lamp Agate

Lava lamp agate. I found it. I named it. Here is what you are really looking at. Rock #4526 This is agate on the right side and lava matrix in which it is formed on the left side, cut and polished and set as a pendant in gold-fill wire wrap. This is a free form designer cut of an agate nodule still attached to the lava in which the nodule formed. If you rotate the specimen 45 degrees counter clockwise, you will see the classical amygdaloidal shape. Rock #4526 rotated 45 degrees For those who may not have the word amygdaloidal on the tip of their tongues or in their lexicon, “amygdaloidal” generally means almond-shaped, typically with a flattened bottom and rounded top. This shape comes from the gas bubble pocket formed in lava which filled in with silica material which formed the agate. This specimen is natural and not […]

Flower Garden Agates

Flower Garden Agates

This is why I love cutting material from The Carver! Rock 4582 Rock 4538 The oval flower garden agate cab has a white fortification agate in the center. A fortification agate is named for the pattern that would be seen on the ground if one were looking down from above upon an old-fashioned fortress—think Fort Ticonderoga. (See Gemstones of the World, by Walter Schumann, page 134, 1977 edition, for discussion and photos of the fortification agate.) The point of this blog, beyond the beauty of these flower garden agates, is that it is very complicated and difficult to exactly identify a particular type of agate, particularly when many agates contain within them several identifiable specific types of agate. Ergo, this is a flower garden agate with a fortification agate in it. Rock #4538 Detail

Brecciated Lava Agate

Brecciated Lava Agate

This stone was cut as a geological oddity, rather than as a gemstone. I doubt it will ever be set as part of a piece of jewelry. First, you notice three jagged shards or pieces on the left side of the rainbow shaped stone. These shards are from hardened lava that was broken and fell into a crack in the lava surrounding the shards. The lava, which was initially molten and then hardened, was at some later point in time broken by tectonic forces or by volcanic explosion or lifted by rising magma. The crack and the shards were later (How much later, you ask? How the hell would I know?!!) filled in by a silica solution or silica gel that subsequently crystallized and formed the brown material surrounding the three shards. The surrounding material is chalcedony (a micro-crystalline quartz structure). Chalcedony is a common material in many agates and […]

Winter Stone Cutting and Wood Cutting in Maine

Winter Stone Cutting and Wood Cutting in Maine

My cutting of the voluminous Carver material continues between wood cutting activity to heat my home. Rock #4604 Rock #4606 Winter is wood cutting time in Maine as the swamps and low places, which are otherwise filled with water, freeze hard, leveling out the low muddy places. I access these frozen places on my ATV and cut and haul out my firewood. I split the wood with my wood splitter and then stack it on my porch (a 2 to 4 day supply), move it inside, and then ‘feed’ my wood stove as needed. Stove and Woodpile Splitter and Woodpile Why do I store wood inside when it is piled conveniently on the porch? Because this morning at 5 a.m. it was 7 degrees above zero and at 9:30 a.m. it had dropped to 0 degrees! Warm wood burns easier than cold wood. Cutting rocks is much easier than cutting […]
