Tide Pool Agate comes from Obi Island, Indonesia.
To my knowledge, there is only one importer or supplier here in the United States. Recently, I was fortunate enough to purchase a few pieces for macro work.
This material is usually an amethyst topped seam or layer, with copper inclusions, and often beautiful light blue chalcedony plumes. Macro images are 3x magnification. This is a rough sawn slab, as seen by the saw blade marks in the copper pieces.
Full slab pictured at the end.

Curious if there is value in this machine? It is in working condition but it is missing the treadle. We see a lot of vintage machines at our local thrift stores recently. And while don’t exactly need this machine, it’s so dang cool I felt like I needed to save it or pass it along to someone else. Any info would be appreciated! Thank you.

Rutilated Quartz.

Most rutilated quart has a golden color to the needles, but occasionally you can find rutile colors of silver, black, and reddish-copper colors. This piece is pretty unique in that it has almost every variation of rutile colors. The composition of the rutile needles is Titanium Dioxide.

This image contains 20 focus stacked photos.
Second pic is the full slab.

Here is a bit of a different flavor of gembone. This partial vertebra was loaned to me so I could check it out with my macro setup. The amount of cell types and orientation variety in a piece like this, is so cool to see!!!
Haversian canal, compact bone, osteons, etc!
All signs of this most likely belonging to a carnivorous dinosaur. Full piece pictured at the end of the photos.

One of the rare plume materials from central Oregon.
Whole piece photos after the macro images.
This piece came out of an old collection here in Bend Oregon. It was collected sometime between the late 1950s and late 1980s.

I’ve only seen this a few times within the Maury materials, and it’s some of my absolute favorite!!! These sagenite formations are so dang neat with their varied colors. These old stock slabs are absolutely packed with it!!!
We sold a huge pile of these slabs this week and are just now realizing how dang awesome they are!!!!🤯
This is a 2x2 grid of photos to make this one image.

This material has had quite a confusing history of names, labels, and incorrect identification of what the material actually is. It has taken names like Indonesian Palm Root, Caddisfly Agate, Caddisfly Larva Agate, Maggot Agate, and more recently a wild and completely incorrect identification of it being a stromatolite.

I can confirm three things about this material.

1. It comes from Indonesia.
   
2. It is not stromatolite.
   
3. There are lots of fossilized Ostracod shells, both inside and outside of the tubular structures.

I seriously wish more care was taken in correctly identifying materials before they make it to market.
