New Polished Batch – Best Yet!

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.

Polished agates and Stones - South Dakota Rockhound

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!

Polished Fairburn Agate

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.

Bubblegum Agates - Polished

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.

Petrified Wood - Polished

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.

Polished Bubblegum Agate

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.

Polished Gray Quartz "Egg"

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.

Polished Red Congomerate / Jasper

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.

Heavily banded agate - Polished

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.

Polished Quartz Variety - South Dakota

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.

Polished South Dakota Agate - (Fairburn?)

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.

Polished mossy agate - South Dakota

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.

Polished Prairie Agate - South Dakota

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.

Colorful Petrified Wood - South Dakota

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.

Polished South Dakota Agate

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.

Polished South Dakota Bubblegum Agate

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.

Petrified Wood - South Dakota

Some of the petrified wood in this batch, showing the variety of forms you can find on the Buffalo Gap National Grasslands.

Polished South Dakota Conglomerate / Prairie Agate

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.

Polished South Dakota Conglomerate / Prairie Agate

Speaking of funky conglomerate-like stones…this one has some very fine patterns that are pretty unusual compared to other pieces I’ve found.

Polished Quartz - South Dakota

The biggest piece in this batch, an almost tennis-ball-sized chunk of quartz with an cool brownish-orange tone intermixed throughout.

Polished bubblegum agate with "eyes"

Sometimes bubblegum agates turn out like this when polished, with just the “eyes” remaining.

Small polished prairie agate

Size doesn’t matter! Even the small little pieces have some gorgeous patterns once you photograph them in macro mode.

Polished Red Splotch Agate

I call this “red splotch agate”. Given I’m still new at this and have no idea of what to really call it.

Polished Red Prairie Agate

Some of the prairie agates have reddish tones, but this one has more red throughout than most that I find.

Reddish polished quartz

Another of the reddish quartz pieces.

Polished South Dakota Quartz

And…one last one, another polished piece of quartz.

South Dakota Rockhounding Display – Complete!!

The age-old question has been answered!  The question (primarily from my wife)…”What are you going to do with all of those rocks?” Minor detail, something I hadn’t thought about much since my son and I started rockhounding this summer!  But given the growing collection in the basement, it was time to figure out how to display some of our goodies.

It’s been a labor of love, but it’s now complete!  Over the last couple of weeks I’ve refinished the printer’s trays I got on eBay, and installed them on the wall of my office.  Given how new we are at this, we still don’t have a huge number of pieces that have made it all the way through the tumbling and polishing process, but we certainly have PLENTY of combined raw and polished material to fill the 178 individual compartments in the two printer’s trays!  I think they look fantastic, and certainly add some wonderful character to my home office!  Here are some photos:

South Dakota Rockhounding DIsplay

The finished printer’s trays, sanded and refinished on the wider cross pieces, but simply cleaned up and left as-is for the individual compartments themselves. I used a brown enamel paint on the wide pieces, but simply sanded off the old paint and expose the metal faceplate on each drawer. The most satisfying aspect of the collection shown here? Every single piece was hand-collected by my son and I, all from right here in South Dakota!

An oblique view, one that shows the bare metal I left on both original drawers.

South Dakota Rockhounding Display - Agates!

For each of the two printer’s trays, I cleaned up the original drawer pull, and repurposed them as labels. The right side is rightly labeled “South Dakota Agates”, as every piece on this side are prairie, Fairburn, bubblegum, or other agates, all collected from the Buffalo Gap National Grasslands.

South Dakota Rockhounding Display - Jaspers, Petrified Wood, Quartz, etc.

The original drawer pull and label on the left piece. This side is more of a “mish-mash” of material, with a lot of petrified wood, quartz, chalcedony, jaspers, and other pieces. Again, all collected from right here in South Dakota!

Prairie and Fairburn Agates - South Dakota Rockhound

One of the six major compartments across the two trays. This one is devoted to prairie agates, and the handful of Fairburn agates we have so far.

Fairburn Agate - South Dakota Rockhound

We haven’t found many Fairburns as of yet, but the one on the right here is the favorite of ANY piece we’ve found so far.

Bubblegum Agates - South Dakota Rockhound

One of the six compartments devoted to bubblegum agates. Some are tumbled and polished, most here have not been polished yet. I like the look of the little bubblegums though, and probably won’t polish most of these. The “eyes” of the bubblegum agates give them a great look then when you do polish.

Bubblegum Agates - South Dakota Rockhound

A closer view of some of the “raw”, untumbled bubblegum agates. You can see why they are well named! They do often look like chewed up pieces of bubblegum.

Petrified Wood - South Dakota Rockhound

The 2nd most common find for us on the Buffalo Gap National Grasslands – petrified wood. These are all petrified wood pieces. Most you find are the grayish or tan color, but there are also some other beautiful colors and patterns you can find. Most of these have not been tumble polished.

Chalcedony and Chert - South Dakota Rockhound

It’s not just agates and petrified wood on the Grasslands! There are other forms of chalcedony, and a huge variety of other rocks as well. I’ve been told those on the right (particularly the bottom right) are chert, in a limestone matrix.

Miscellaneous Prairie Agates - South Dakota Rockhound

A closer look at some miscellaneous (prairie) agates. There’s quite the variety of colors and patterns that you can find.  All here are polished, except the one in the upper right.

Misc. Jasper and Quartz - South Dakota Rockhound

A few miscellaneous jasper, quartz, and agate.

Large agates, chalcedony, etc. - South Dakota Rockhound

The only downside to the use of the printer’s trays…some of the compartments are relatively big, but the depth is quite shallow. Bigger pieces thus won’t work. I haven’t quite decided how I want to display them, but for now I have a table directly underneath the display, and I’ve started to put out a few big pieces. These are some big chalcedony pieces, prairie agates, and petrified wood.
