There are two moments in polishing stones that are akin to Christmas morning for a kid. One is after the first rough polish. It’s at that stage where you get some wonderful hidden surprises, where the rough polishing has removed outer material and exposed some beautiful patterns underneath (happens a lot with bubblegum agates, for example). The second big moment is taking a batch out of the final polish. It’s a long process to polish rocks! I’ve learned patience, and it’s usually a two-month process to go from rough material, to a beautiful, shiny final product. Here are photos of the latest batch…my best yet, without question! A wonderful mix of agates, quartz, petrified wood, and jaspers. And the best aspect of this batch…EVERY piece was self-collected, on the Buffalo Gap National Grasslands here in South Dakota.
An overview of the final batch. In this batch, I included a wide variety of stones, including many different agates, petrified wood, quartz, and jaspers. The one thing they all have in common…they all came out WONDERFULLY shiny!
A surprise! This is one of those agates where there’s a surprise underneath a weathered outer layer. I suspected there might be something special underneath the heavily weathered exterior of this piece. There certainly is…the beautiful, fine banding of a Fairburn agate.
Typical bubblegum agates. Once polished, most seem to show the reddish and cream colors of the agates shown here. Once the little eyed nodules wear down in the polishing process, you can get some truly gorgeous colors. Best of all, bubblegums take a VERY good polish and shine.
This is the most common form of petrified wood that I’ve found on the Grasslands. You do have to be careful polishing, as sometimes the wood pattern is only on the exterior of the piece and may wear away if you polish too much. If you’re careful though, you can get a beautifully polished piece such as this.
This is small piece, the diameter of a penny. But HOLY COW do some polished bubblegum agates look wonderful when polished. In this case, the entire outside of the bubblegum was black when I first put it in the polisher. Many times that black wears completely off, often leaving the typical red and cream colors of bubblegums found here. On this one, I stopped the rough polish while it still had some black “eyes”. Gorgeous little piece.
There are pieces of quartz on the Buffalo Gap National Grasslands of many different colors. This smoky gray piece polished up beautifully, particularly after I left it in the rough-polish stage for many weeks to get the “egg” shape.
I don’t know what to call this piece, but it’s freakin’ gorgeous! It’s pretty much one-of-a-kind for pieces I’ve found on the grasslands.
Most of the prairie and bubblegum agates you find have some form of banding. Many have some very fine bands. But this piece has more “layers” of thin banding than most pieces, and it has some incredibly beautiful colors as well. It’s got an unusual shape, and I was tempted to keep it in the rough polish phase for several more weeks to get a more rounded shape. Given how beautiful it is, however, I didn’t want to take a chance it might break apart, so did the final polishing on this unusual shape.
Some of the polished quartz pieces from this batch. Clear, White, and pinkish tones are the colors you find the most, but there are others as well. ALL polish up beautifully.
Another agate where the pattern underneath really wasn’t revealed until after many weeks of polishing. It’s not as obvious as the Fairburn above, but there are some hints of a Fairburn-type pattern.
I know there’s a kind of agate called “mossy agate”. I’m not sure that’s what this is, but it’s such an unusual piece. The pattern itself is quite unusual for agates I’ve found, but so is the mossy, orangish patterns that fill in the gaps between the white blobs. Cool one-of-a-kind piece in my collection.
From an unusual piece above, to a pretty common piece. While creamy and white banded prairie agates are the most common color form I seem to find, I also often find ones like this, with blackish bands in a creamy matrix.
The grayish petrified wood near the top of this post is easy to find, but you do also sometimes find more colorful pieces. This one has some wonderful reddish tones, as well as a bluish streak on the back side.
I kept putting this pieces back through the rough-tumbling phase, trying to wear a bit more off of this side to try to reveal more of the different colors. But alas, it kept getting smaller and smaller, but with the same color pattern.
Another great little bubblegum agate. Some of these pieces end up showing many little eyes once polished, but many also often show some gorgeous banding underneath.
Some of the petrified wood in this batch, showing the variety of forms you can find on the Buffalo Gap National Grasslands.
I’m not sure what you call this…a prairie agate, or some kind of conglomerate. Prairie agates here seem to often be banded, but some too do look like a mish-mash of fragments that have been found together. The conglomerate-looking ones really can have some cool patterns once polished.
Speaking of funky conglomerate-like stones…this one has some very fine patterns that are pretty unusual compared to other pieces I’ve found.
The biggest piece in this batch, an almost tennis-ball-sized chunk of quartz with an cool brownish-orange tone intermixed throughout.
Sometimes bubblegum agates turn out like this when polished, with just the “eyes” remaining.
Size doesn’t matter! Even the small little pieces have some gorgeous patterns once you photograph them in macro mode.
I call this “red splotch agate”. Given I’m still new at this and have no idea of what to really call it.
Some of the prairie agates have reddish tones, but this one has more red throughout than most that I find.
Another of the reddish quartz pieces.
And…one last one, another polished piece of quartz.
