Morocco Stalactite Geode

Morocco Amethyst Quartz Geode with Stalactites

Morocco Stalactite Geode

Click image for slide show

[2] [3] [4] [5] [6] [7] [8]

This is a wonderful specimen, an Amethyst Geode from Morocco! It is filled with stalactite crystals. The coloring of the crystals has a reddish tint, we believe from Hematite, or 'Hematoid' - as we have seen it being marketed. It is a complete nodule, able to be fit together. However, please note that it is delicate and we would recommend against handling it much once received. From the photos you can tell that besides the line that separates the nodule halves, there is another fracture line. It is not loose at this time, and to our knowledge, or from what we can tell, it has not been glued. But it is none-the-less an absolutely stunning display! It measures roughly 4" x 3" x 3 3/4" and weighs 1 lb 6 ounces, or 620 grams. You will receive both sides of this exact unique piece.

See video of the pair. (Hit back arrow to return to this page.)

Oco Geode

Small Oco Geode with Agate and Crystals

Oco Geode

[2] [3] [4] [5] [6] [7] [8] [9]

This is one half of a small, polished Oco Geode nodule, a natural stone from Brazil filled with Agate and Quartz. The centers are full of crystals, some larger, some smaller, surrounded by agate. Each piece is unique, no two are exactly alike. They come in amazing variety as you can get an idea of from the photos. You will not necessarily receive one of those you see in the slide show, but these are good representations, similar to what one could receive.

Each one has been polished on the face, bringing out the natural beauty of the agate. Sizes vary, mostly between 1-2" long x 3/4-1" wide and 1-2" thick. But as each piece is one of a kind, you could receive one a little smaller or larger. The weight of each one can be less than an ounce or up to about 2 ounces. If you receive one you are not happy with, just send us a message and we will help ensure you are completely satisfied with your transaction.

Whether one is a collector or lover of rocks and gems, minerals, or crystals, these little stones are awesome for delicate accents in the home or office, or on a shelf for display.

U.S. shipping cost: $3.50 First Class

Mexican Snowball Agate

Polished, Domed Mexican Snowball Agate

We had this one marked as a Laguna Agate nodule, and then we thought it might actually be a Coyamito Agate, though neither quite looked as we thought they should. HOWEVER, since that point we've learned more and more, and I just noticed the back on this one. Judging from the matrix, I'm pretty sure it is actually a Mexican Snowball Agate. (No photos of the back right now, but will take some soon, or upon request if you don't see the back before I get to it!) Our understanding is that Snowballs may be weathered agate cores of fully expanded thundereggs. Please note that it is domed on the surface, the rough nodule on the back. It is approximately 1 1/2" x 1 3/4" and is between 9-19 mm in thickness. It weighs 28 grams, just less than an ounce.

Polished Thunderegg with Black Agate

Black Agate Thunderegg

Click image for slide show

[2] [3] [4] [5] [6] [7]

This is a pretty little thunderegg. Unfortunately we're not sure of the locality on this one. My first guess would be Black Rock Desert, or maybe from the Black Agate Mine area of Wiley's Well? Kind of a brick red matrix with clear and black agate, and a very small area of waterlines. It is about 1 3/4" x 2" and 14 mm thick. It weighs 53.4 grams, or 1.8 ounces.

U.S. shipping cost: $6.80

Black Agate Thunderegg   Item# 2742   Price: $6.00  


Amethyst Thunderegg

Polished Wileys Well Thunderegg with Amethyst Crystals

This is a thunderegg (a geode) with a small pocket of light amethyst. I believe it is from the Wileys Well area, but I'm not certain and don't know which bed if so. Lots going on in this one. It's polished on the face, but notice in one of the photos, you can see a small edge that didn't polish like the rest. I didn't notice it until I saw the photo. It is about 2 5/8" x 2 5/8" and 61 mm thick. It weighs 370 grams, or 13.1 ounces.

U.S. shipping cost: $5.50

Oregon Thunderegg

Unpolished Oregon Thunderegg with Common Opal & Dendrites

This is another thunderegg with some common opal in it, but it also has awesome little dendrites as well. It is not polished at all. It is another of the numerous miscellaneous sliced pieces from any of the various collections we've acquired. We believe it is from Oregon, Richardson's Ranch, probably Blue Bed. It is 3 3/4" x 2 1/2" and 22-23 mm thick. It weighs 217.9 grams, or 7.6 ounces

U.S. shipping cost: $6.80

Richardson's Ranch Thunderegg

Unpolished Richardson's Ranch Thunderegg

This is a very neat unpolished Thunderegg, we think from Richardson's Rock Ranch. It is roughly 3 1/2" x 3" and about 2 1/2" thick. It weighs 600 grams, or 1 lb, 5 ozs. It is not polished, but it has had a bit of sanding already. Beautiful, colorful patterns in this one, but please note that in natural lighting, it is not as bright as it looks in the photos. Additionally, it was photographed wet in most of the photos.

U.S. shipping cost: $6.80

Polished Wileys Well Nodule

Wiley's Well Thunderegg with Neat Inclusions

This is a Thunderegg from Wiley's Well area, polished on the face. It's filled with crystals and agate, with a flat, solid face. You'll easily notice the 'rabbit ears' about the center, but there are several other inclusions that look like they'be been kind of 'stuck' near the 'ears.' It's 3 1/2" x 2 1/4" and about 1 1/2" thick. It weighs 280 grams, or 10 ounces. A beautiful piece to add to any collection!
