And given that I didn't know about loading according to hardness when I started this batch, I'm pretty dang happy with the results. I'd say about 60% of the batch were rejects, but my plants will adopt these "smooth but not shiny" friends for pot decoration. Some took a great shine - the "jades" from Moonstone Beach faired the best, I think. Forgive the excess of lint - I dried everything with those blue utility paper towels and they leave lint everywhere. The gallery's been updated (as well as the blog) and here are a few "highlights" from the batch. The keepers: My "mystery stone" - any guesses on what this is would be much appreciated. The flecks are not physical holes, but are in the stone itself and although they appear white in the photos, they're actually a really pretty baby blue. What-the-heck-am-I? You can actually see the reflection of the front of my camera lens in the shine. ;D edit: I just discovered this stone is translucent! It certainly appears black, but in front of a strong light, it shines a gorgeous deep cognac brown color (in case this helps with ID)I think we determined this was jade... Most of the "green meanies" plus the pale translucent pebbles that might be moonstone but probably aren't really. lol Quartz? Whatever it is, the gold striations are pretty. This one will definitely be set - deep dark red on a black base. Anyone guess what this is? This will be set too - beautiful greens, reds, & golds (jasper?) I'd like to know what this is too (if someone says "chert" i'm gonna scream) - steel grey with those rust colored areas. Very neat looking. Hematite? (on the CA coast??) Thru the Loupe - thanks for the idea to whomever it was who managed some shots thru their 10x loupe - it was fun! This is the "black mystery stone" again... I also noticed that several of my jade pebbles from Moonstone Bch had bluish areas. No, this isn't wishful thinking or rub-off from joining the Pacific Jade forum ;D they're really there. lol This one has the largest area of blue - but it doesn't translate well on the camera's sensor. Another "thru the loupe" pic - a jasper piece with a little area of quartz crystals that I didn't even see until I viewed the photo! That's all - the rest are in the gallery if'n you wanna see more. Thanks fer lookin' !!! Nancy

This is an excellent batch. The finish is excellent given that you mixed different kind of rocks in the batch.
Thanks for sharing.

Very nice batch! Great shine on some of those. The red/yellow breccia one (yellow jasper in red agate) is very nice, but my favorite has to be that red/black one. Very nice!

Great job! What equipment did you use? Try anything special in terms of your process? Thanks! I didn't do anything special. - Lortone 3A 3 lb tumbler (about as basic as you can get).
- 1 tumbling cylinder for all grits (I do clean it out very well between, though).
- The final 3 of a 4-step grit kit (120/220, 500 & CCP Polish, 1 week in each).
- I added plastic pellets to the 500 grit and polish cycles.
I guess I got lucky in that the 60% or so of soft stones didn't ruin the batch - now I know better than to even pick those up, though. My mistake was that I tumbled before reading (this forum). Nancy

Thanks to everybody for checking out my "maiden batch". The shine could have been better but I was too anxious to get them out and see how they looked. Next time I'll know better (for sure) and probably will do 2 weeks/charges of the polish stage. Nancy

Good job on the tumble. I love miscellaneous beach rock tumbles.

Great tumble! To answer you Chert question- NO- THat finish (more matte than shine) is probablt due to the rocks softer composition- most likly limestone or a fine grained sandstone. Chert will take and incredible shine being as it is a quartz rock. Great job on the rocks and I loved the closeups!!

This one looks like a classic example of red jasper indigenous to the Pacific northwest and commonly found on coastal beaches. If i'm right, it may possibly contain enough residual hematite to be mildy attracted to one of those powerful rare earth neodymium magnets. Here is a chunk that I collected from my top secret collection beach here on Vancouver Island that I tumbled last year. Some more examples (please excuse the residul white polish, these were taken right out of AO and before the final cleaning cycle.) Lots of hamatite in this one, you can see the dark silvery shine of it. This one looks more like serpentine than jade but I'll wait for Tony (Nephrite) to chime in on it.

LCARS - thanks for the ID on the red jasper. I have a few more like that in the present batch (going at 500 now) - it's really pretty. Don't have any RE magnets to test the hematite content though - I'll have to pick one up one of these days. That last one is translucent in many of it's green areas which is why I didn't label it serpentine (is that a good general rule of thumb?). It does look like it has areas of quartz or other clear to whitish composite, too.

Could the Mystery Stone be Obsidian? I've got a few that have not been tumbled that look black til you hold them up to the light. Then they are a smoky black/deep brown. Kinda looks the same as I have.

a really pretty batch. I have my loop right next to me at all times when working with stones and rocks. There is nothing like getting a real close look at what you have even if you don't know what the rock is.
I think the yellow in the white is quartz as I collect a lot of it on the beach. The yellow lines and striations can be really bold at times.
Sorry I missed this when you first posted
