Odd/Rare/Perfect: How I Evaluate Agates and Geodes, a Carver Report

This report highlights several Carver agates/geodes cut in the winter of 2026. I have selected stones that are either odd or rare (seldom found or observed) or perfect or near perfect in one or several regards. Some I will merely categorize, and I will provide a short explanation of my categorization criteria for others. If I merely categorize a stone without explanation, feel free to contact me for more explanation.

ODD

Images 6791, 6792, 6793 below—3 different aspects of a rock I call Deep Pit Rock—represent well my “odd” category. This is a hand ground and polished blue agate nodule (could be a geode, but without cutting it I can’t tell) from the, so called by me, “Deep Pit” area of The Carver Agate Field. The Deep Pit area was featured in Rock and Gem Magazine in an article, written by me and Bill Halepeska, entitled Captivating Find at The Carver Agate Field. Why is it odd? Do you really have to ask? It is about the size of a large grape. Sagenetic “starburst” features, likely of hematite, make it odd and very cool.

PERFECT

The stones below—6795 and 6800—represent my perfect category. They are carnelian agate/nodules/geodes with perfect banding. Zoom in on 6800 and take a look at what can be seen in the geode center—odd!

Another example of perfection is stone 6788, seen below. Its coloration and variation of balanced sagenitic types and structures, and the perfect blue fortification agate in its center, all suspended in nearly clear chalcedony without cracks, combine to meet the perfect category. In other words, several different dimensions together equal perfect in this case. If you find an agate nodule this perfect, put it in your private collection and do not part with it.

Rock #6788

Rock #6813

Stone 6813 above falls into the almost perfect category. It has perfect, fine, uniform banding without cracks. It has perfect yellow blobs on the bottom of the rind, suspended in an almost clear chalcedony framed by white agate banding. And, oh yeah, a very cool geode center. The only imperfection is in the outer rind.

Stone 6825 (below) is almost perfect. The pink outer rind is missing on the lower left of the stone, otherwise it has perfect banding and a floater surrounded by euhedral quartz with red dots, making this a great specimen. Another almost perfect stone is 6833, also seen below. The rind is unfractured, the banding is perfect, the blob of green sagenitic material in the lower left surrounds a dark brown shard of lava. Only the crack running from the shard of lava upward to the left destroys this specimen’s perfection.

RARE

Rock #6721

Rock #6722

Stones 6721 and 6722 above represent my rare category. These are the two halves of a three inch long green geode with a cool pink crystal filled void. My late friend, mentor, geologist, and self-described rock enthusiast, Bill Halepeska, of Midland, TX, searched most of the famous West Texas agate fields, including The Carver Agate Field, from the 1960’s to 2020. He opined that green agate geodes and nodules were the most rare color. My observations, after over 20 years of cutting The Carver Agate Field, are that he was correct. This is indeed a rare specimen because of its green color, the pink geode center, and the fact that it contains no fractures. This combination is very rare.

Rock #6779

Stone 6779 above is also rare. This fragmented filament agate with the purple-ish fragmented filament portion is a very rare color, especially when paired with the green fortification agate seen in the top portion of the stone. As discussed above, a green fortification agate is very rare in West Texas. Hence, this specimen falls in the rare category for these two different reasons.

RARE/PERFECT

Rock #6811

Rock #6812

Stones 6811 and 6812, both shown above, fall into the rare and perfect category. They contain an incredible number of colorful sagenitic structures and shapes with very few fractures or cracks. Stone 6811 is almost flawless: it is interesting, unique, beautiful and nearly perfect. You can tell I really like this stone.

Stone 6818 below falls into this category. With a yellow fortification agate on the left side, this colored plume agate of white, pink, orange, green, and yellow has no fractures or cracks and none of the outer rind is broken or missing. This stone’s rare sagenitic features, while subtle, will be of interest to serious ‘rockers’ even though it does not immediately jump out at you.

Rock #6818

Last but not least, stone 6822 seen below has no fractures, no imperfections of the rind, with a perfect fortification agate and multicolored plume agates. Add to this two white spiny looking structures (think white sea urchins) which are worth zooming in on to take a look. I was psyched when I cut this open. It will remain in my personal collection. It is rare and perfect!
