Newest cuttings reveal four agate nodules, one geode, and one fortification agate in a single cabochon! …And many more cool stones

Click on the images below so you can zoom in on the details! Here we go: Rock #5300See enlarged photo below Detail of Rock #5300See four agate nodules, one geode, and one fortification agate in a single cabochon Rock #5291Reminds me of Lloyd Bridges and Sea Hunt — an underwater scene (for those too young to remember Sea Hunt) Rock #5293A fancy free-form agate Rock #5299Looks cracked but it is not. It’s brecciated jasper with silica between the fragments Detail of Rock #5299 Rock #5298My favorite type of stone for cutting — jasp-agate with crystal lined vug Rock #5305The white top and bottom of this stone evidencing another ‘Bullfrog’ agate, named by me Rock #5337Geode in vein agate Rock #5338Designer free form agate cab cut from the above vein agate (Rock #5337) Rock #5308Spectacular flat topped jasp-agate cab with two blue fortification agate inclusions The three stones below — #5317, […]

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

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.

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 […]
