Fragmented Filament Agate from The Carver Agate Field + Video

Fragmented Filament Agate from The Carver Agate Field + Video

Between gardening, yard work, and carpentry projects, I have been cutting a few stones this summer. The video below gives you a quick look at what I have been up to. Most of the stones are pretty, but one in particular (the fragmented filament agate) looks like a bottle full of eyebrows or eyelashes. You may ask “What the hell is a fragmented filament agate?” Well, I am going to tell you. Nodules, geodes and agates often form in the inside of gas bubbles that form in lava. The bubbles form while the lava is still hot and pliable. Later, after the lava has cooled, water containing silica and minerals permeate the lava and cracks in the lava entering the ‘bubble’ (technically called a vesicle or vug). Some of these minerals and silica will form a thin layer on the inside of the bubble. This thin layer sometimes scales off […]

Four Stones I Just Cut and Really, Really Like!!

Four Stones I Just Cut and Really, Really Like!!

Photos 1 and 2: The huge 2 1/4″ cabs were each cut from the same Carver agate/jaspagate. Each has spectacular coloration and pattern and a tiny bluish fortification agate to set off the red/yellow/orange/green coloration. Photo 3: This Carver agate came from a geode slab I cut. Enlarge this picture by clicking on it and take a closer look!! One of the most beautiful agates I have cut! The tiny ‘vug’ goes nearly through the stone and is set off by blue banding. Photo 4: Carnelian agate with spectacular gold sagenitic inclusions.

Easter Gallery from ‘The Carver’ Agate Field Collection

Easter Gallery from ‘The Carver’ Agate Field Collection

Another two weeks of exploring, cutting and polishing stones from ‘The Carver’ agate field. Please visit the new Maine Gallery entitled ‘Easter Gallery’ to see them. These stones are from several different areas of The Carver agate field, hence, many look quite different. These specimens display some of the best colors and patterns. Try viewing them on a large screen if you can. Also try to see the amazing stones’ structure via enlargement. Not included in this gallery is another ‘first time seen’ from ‘The Carver’ agate field. The next posting will feature this ‘first’!

7+ Pound Banded Blue Agate with Geological Oddity Found Inside

7+ Pound Banded Blue Agate with Geological Oddity Found Inside

The ‘deep pit’ on The Carver agate field ‘popped’ a 7+ pound,  6 1/2″ x  3 3/4″ banded blue agate beauty! While the ‘deep pit’ photo gallery on this website has lots of photos of ‘deep pit’ beauties, this specimen contains a large yellow inclusion (on the left side of the photo below) which has a blackish dendritic agate formation in and on its surface. A dendritic agate is a tree-like or fern-like image.  The word dendrite is Greek for “tree-like.”  Normally, these dendritic formations from The Carver have formed on the outside surfaces of a geode or nodule, as shown below in photo 2849.  What is geologically odd is that this dendrite formed on the yellow material which broke off and fell into the gas bubble pocket, which was then encased inside the larger blue agate when it later formed. I believe this was likely an 8-step geological process, […]

Metallic Mystery Agate

Metallic Mystery Agate

This agate formed in association with a yellow jasper (which is predominantly comprised of silica). Before I cut this Carver find, it displayed a curious metallic sheen which was in fact what initially drew my attention to it.  The sheen was very different from the sheen observed from other quartz and jasper materials.  This metallic sheen appears quite clearly on the bottom of the pictured cabochon. The rounded surface of the cabochon shows agatization and two visible “vugs.”  The stone from which this cab was cut also had a curious and unexpected heft (weight) that, combined with the metallic sheen, suggested a metallic component had mixed with jasper and formed  a metallic mystery agate that had not been previously observed on The Carver agate field. If I can find out what metal is involved I will update you.  

Agate “Vugs”

Agate “Vugs”

Some, but not all, agates contain “vugs,” tiny voids often filled with quartz crystals.  They are a sort of miniature geode.  The crystals when present are usually very petite (sometimes microscopic). Note that two of the three vugs pictured in the image below have visible quartz crystals.  Some lapidists view vugs as imperfections to be avoided when cutting a stone.  I, however, love to include vugs when cutting cabochon. I like to see the sparkle that often emanates from the vug when a tiny crystal catches a ray of light. Including a vug in a cab adds beauty, uniqueness, and perhaps, as some believe, mystical powers.  I do not know the technical name for the type of agate shown. In fact, many agate types are unnamed or have local names which have been applied to them.  If you would like to name this type of agate, let me know what […]

Chaos vs. Orderly Perfection

Chaos vs. Orderly Perfection

Formed within tuff, a white volcanic ash which has been compressed and hardened, over millions of years, to a very limited extent, is what I describe as a “chaos agate.” That is not an official agate designation, however.  Apparently, a hodgepodge of mineralization mixes with and in a silica-rich solution which subsequently hardens within the tuff. Since this type of agate forms in a ashy mass, the agate has no orderly shape or form. Chaos Agate On the other hand, here is the orderly perfection  of a cabochon from a cross section of a geode.  If you follow this website, you are probably aware that the orderly shape is from the gas bubble in the lava in which geodes form.  A silica-rich solution and mineralization fill the gas bubble and create the geode’s shape.  The gas bubble fills with silica and mineralization through the ‘fill tube,’ so called, which is […]

Design Challenge Leads to New Design and First Pendant

Design Challenge Leads to New Design and First Pendant

If you follow my work, then you know I design sterling silver settings to highlight the unique characteristics of each designer free-form Carver gemstone that I cut. I previously have made sterling silver bracelets which I have thought were best at emphasizing each gemstone’s beauty.  The setting is secondary to the stone! Recently, however, I  cut a Carver geode with several unique characteristics, including a striking petite red feature and a crystalline lined geode center, which begged for something different.  The challenge was to design a setting to highlight the stone’s crystalline pocket which, without doubt, is the most unique feature of the stone. A mirror and the decision to create a pendant, not a bracelet, was the answer!  Viewing the creation will explain this choice.  This is a totally new design and the first pendant which I have offered for sale. Visit the Shop to learn more.  

New from the Carver Agate Field: Is It Jasper? Agate? Jasp-Agate?

New from the Carver Agate Field: Is It Jasper? Agate? Jasp-Agate?

These definitions will help us decide! Jasper:  opaque (light does not penetrate); any color of chalcedony which is a micro-crystalline (requires magnification for crystals to be seen) form of quartz. Agate:  a banded translucent (lets light through) chalcedony of any color, most often found in nodules, geodes, or cracks in silicaceous volcanic rocks. Jasp-agate:  a chalcedony with characteristics of both agate and jasper.  The basic component is silica (quartz) which may be either micro or macro crystalline (crystals can be seen without magnification).  It can be opaque, transparent or translucent (sometimes all three appear in the same specimen).  It can be banded like an agate or it can be like a jasper with agate structures which form within cracks or fractures or vugs (small cave-like voids) in jasper. If you would like to see some of the Carver Agate Field jaspers and jasp-agates, take a look at the new JASP-AGATE […]

New Year Powder Blue Fortification Agate Bracelet

New Year Powder Blue Fortification Agate Bracelet

This bracelet and its powder blue agate stone were created just before Christmas 2019–the only bracelet I made in 2019. It is a great start for 2020 and is gemologically interesting. Though at first, this blue agate may merely seem beautiful and elegant, it is much more, particularly if you like rocks like I do! First, the lower right hand corner of the stone has a half moon shaped blue area of finely banded agate. This fine blue banding displays opalescence, e.g., its blue color and reflectivity subtly changes depending upon the intensity and type of light (natural, incandescent, fluorescent, LED, etc.). Second, the orientation of the stone to the light will change its reflectivity and brightness.  This is very much what you would see with certain types of precious opal.  Third, the fortification agate (named so because it has a shape with angular corners, like looking down from above […]
