Bullseye Agate, from Goldfield, Nevada it actually is more Chert and Rhyolite and has a little bit of a kaolin look to it. Freshly collected material or at the bottom of the pile material tends to be more yellow unless oxidized or given some heat treatment — if I remember right it heat treats at a low temp, I think around 425, which is easy to do in a fire pit. These are rough stones and have some fractures, but they do cut into nice slabs for cabochon and jewelry work. One large rock (at least 10 pounds) would make great slabs. One usage I had not thought of was for knife blade handles. This would be an incredible stone for that purpose. I would apply a resin to seal and if there are flaws they can be sealed by Zap-a Dap.
The sizes range from one pound rocks to one ten pounder. The best shipping would be in flat rate boxes. All my rocks can be combined. |

HOWLITE Nodule- Turquoise Impostor
Soft white bumpy aggregations. Scratches with Obsidian (glass) but not with a copper penny. Mohs 5?
This Howlite was collected on the West coast, most likely Ticks Canyon, CA. Howlite is usually dyed because white howlite receives little attention in the marketplace. Most people think that it is boring. However, when it is dyed to a brilliant or pastel blue, green, red, yellow, or purple it catches people’s eyes. Hence the name “Turquoise Imposter.” Cut, with a face on the bottom it makes an interesting book weight. Sliced into cabs they make an interesting item. I have some listed under SLABS. |

Mahogany Obsidian I have an enormous collection of obsidian. The best way to ship rocks is with USPS Priority Mail Medium Flat Rate Box (11″ x 8.5″ x 5.5”) Some are of lapidary quality and can be used for napping, cabbing or any other lapidary purpose. If napping is your priority let me know and I will select accordingly. I have Mahogany, Jet Black, some Sheen and other Oregon obsidians. If you need larger pieces, I can send you some with the large flat rate box. |

Turtle rock. The matrix is a sandstone or mudstone 3.5 to 4 hardness and polish better than one would expect. The spots are more than likely a type of feldspar. The lumps are 5.5 to 6 hardness. The two varied materials will polish differently as well. These “stone turtles” evolved from the northern shores of the Olympic Peninsula in WA state. Even with polishing there is an inherent matte finish to these stones but covering them with a lacquer finish works quite nicely. Trying to tumble or using a grinding wheel will wear away their intriguing “bumps and contours.” If slabbed for cabochons they certainly can be worked the normal way and make surprisingly nice jewelry.
The matrix may upon occasion be naturally darker, even brown and the inclusions can sometimes be yellow instead of white. As they are one in a thousand, I will not be selling any of those. “Turtle Rock” is Variolite.

These Nipoma-like Agate nodules are a collector’s dream. Most are small in the quarter pound range or less. They are one of the rarest and most coveted of all sagenite agates!!! As they are the remains of one of our rock club members now passed on, I do not know where they are collected – but they are much sought after and often sell for 25.00 a pound |

Petrified Wood I have a large collection of Oregon or Washington collected material. As the picture shows they range from fifteen pounds to about 1 lb. Some smaller pieces for the rock id tray are also available. I am presently cutting one large slab. |
