Noon EST    Sunday    1/13/19        at

This slideshow requires JavaScript. will be posting 24 Coyamitos never offered before and the ten best from the group that was taken down when 200 new agates were posted on December 16th, less than a month ago. My six ETSY stores are like the departments in a department store, there are six different departments:

The Agate Trader
The Jasper Shop
The Thunderegg Shop
The Slab Shop
The Cabochon Shop
The Jewelry Shop

I am in the process of upgrading all six stores beginning at the top of the list. This Coyamito posting will be the last offering of new polished half nodule agates for a while. I will move down this list adding new material to the other stores and improving their organization. You can visit any of these stores by visiting and jumping to the shop of your choice.

I hope that 2019 will be a great year for agateers around the globe!
Best wishes from Thom,


A re-stocking sale of 200 agate specimens

Posted on Updated on

stibnite in agate LOGO2.pngAll six of my ETSY stores are NOW OPEN again and a Re-stocking sale at The Agate Shop is scheduled for Sunday, December 16th, at noon EST

RESTOCKING-SALE means all new items, larger inventories and lower prices!

There are agates from Argentina, China, Mexico, Morocco and Patagonia. Within each country there are markers that show the beginning of each location, for example the locations in Argentina are Condor, Entre Rios and Puma agates. When you get to the bottom of a segment you can move to the next group at the bottom.

If you search by the country names ETSY will toss them into disorder. To restore order simply select ‘custom’ at the top right of the sale. Scroll up and down and the agates will remain in order.

I should warn you that putting an agate in your cart will not keep someone else from buying it, to make sure it has not sold make your purchase and then continue shopping.

I hope you enjoy the sale,
Thom, The Agate Trader


From now on all six stores will be open and new specimens will be arriving regularly.


The Portland Regional Rock and Gem Show is happening October 12th through the 14th

Posted on Updated on

Agates Galore                   Julian Grey of the Rice Museum

Hello to all Agate fanciers,

I invite all the Agateers: miners, lapidaries, collectors, dealers and just plain rockhounds to come by for a visit at the great upcoming event in Canby, just east of Portland, Oregon. The ‘Portland Regional’ show is great partly because this show continues an historic tradition, now reopening in a new venue. Canby is just to the east of downtown. The ‘Regional’ is still the major show for Oregon rockhounds and for visitors from all over. The reason in part is that Oregon is one of the most agate rich areas in the world, situated over a string of calderas that begins to the south and runs all the way to the most recent, the Yellowstone National Monument. The outstanding Caldera in Oregon contains Three Fingers Butte and it is the source of the great variety of Owyhee picture jaspers with over 70 distinctive deposits. Just 20 or so miles to the south are the Morrisonite and Carrasite jasper deposits, Morrisonite is considered the finest gem jasper, The King of Jaspers. About 50 miles northeast of Three Fingers Butte and closer to Boise, Idaho, is the Graveyard plume agate deposit with many distinctive varieties. Regency Rose, mined by Gene Mueller and Jake Jacobitz, is the most famous for it’s color variety and there are exciting new deposits about ten miles to the East where Philip Stevenson is mining the Feather Ridge and the Linda Marie mines, both yielding very fine plumes.

Another famous area is around Eagle Rock in the Ochoco Mountains just east of Prineville. The landmark Eagle Rock is the source of a fine black plume and nearby are the ranches that produced Carey Plume, Neydiggger Plume and others. Behind the Ochoco reservoir is found the rare and beautiful Ochoco Rim Jasper. Down by Lebanon is the RockCastle rock shop where you can get the legendary carnelian agate from the Polly Drumond bed, Gary Green jasper and many other famed oregon agates and jaspers. Closer to Portland the Columbia River Gorge is the home of Biggs and Deschutes jaspers.

The state rock is the Thunderegg and the most famous area for great plume thundereggs is the Richardson Ranch and its immediate neighbors including the Kennedy Ranch. There are many more deposits of fine thundereggs scattered around Oregon in its numerous rhyolitic lava flows.

Portland also boasts the outstanding Rice Museum, just 12 miles east of Portland on Highway 26. This is just a scattering of the many great locations that made Oregon the place where the Rockhound bonanza began right after WWII, came to it’s full force between 1960 and 1990 and is still going strong today. The Portland Regional Rock and Gem show is hosted by the five Rockhound clubs still active around Portland.

Because of Oregon’s rich deposits of agates and jaspers and thundereggs the Portland Regional show offers great shopping and socializing for three days, October 12th through the 14th. If you can make it you will be able to get some real treasures. There are two collectors from out of state that I know will be dealers there, Philip Stephenson will be just back from his mines and I will be offering some fine polished specimens from my collection that I accumulated over the last fifty years.

I hope you will be able to be here for this exciting event.


Big Reopening in November

Posted on Updated on

The Agate Trader stores are ‘On Vacation’ until November and this is why. For the past year I’ve been involved in the sale of a house I built back in 2000 that involved legal battles and lots of stress. The website has been open but not very active. My house finally sold just a few weeks ago, the funds are most welcome… and what does an avid agateer do then? Why go shopping for agates of course.

I will be in Oregon until October 18 for a great rockhounding adventure and then the website will undergo many changes. In early November all the stores will open again, there will be lots of new material and improvements.

I will post about the opening right here but if you are on my mailing list you will get emails… to sign up please send an email to with the title ‘Add me to your mailing list’ and include your name and email address.

Upcoming Shows
Thom Lane with The Agate Trader shop at the Denver Gem and Mineral Show 2016.I will be a dealer at the Portland Regional Rock and Gem Show in Canby, Oregon, October 12th through the 14th.

I will also be showing in Tucson at the Hotel Tucson City Center for 12 days beginning January 26th, 2019, in Room 234.

Please look forward to many fine new agates, jaspers, slabs, thundereggs, cabochons and more when all my ETSY stores experience a major reopening this November.

My best regards,
Thom Lane

Arizona Round Mountain Agates

Posted on Updated on

An offering of the rare Arizona Antique Pink agates from the collection of Grant Curtis will open Sunday, May 20th, at noon, EST. The sale will take place at The Agate Trader.

This is the second of a series of 3 offerings of rare banded agates from Arizona. The names and locations are:

Night Sky bed                       Mulligan peak near Clifton, Arizona
Arizona Antique Pink         Round Mountain, Arizona, near Lordsburg, New Mexico.
Chimney Bed                        Near Fourth of July Butte, Buckeye, Arizona

Grant Curtis’ father was a mining engineer at Phelps Dodge and he liked to collect agates with his son starting when Grant was only seventeen. Now at 70 Grant still actively prospects, mines, cuts and polishes his discoveries. He shares his vast knowledge of Arizona agates as well as many others locations in the US and Mexico through his web store, The Agate Collectors Dream.

Have a great summer and add some fine agates to your collection when you can. I’ll be busy up in Oregon visiting the Prineville and Madras shows and selling at the Summerfest at the Rice Museum as well as the Portland Regional Show.

All the best,


The “Round Mountain” Agates of Arizona Opening this Sunday, May 20, 2018

Posted on Updated on

Another selection of fine banded agates from Arizona that were collected and finished by Grant Curtis will be for sale. I built my Arizona collection when I was a regular visitor to Grant’s house in Arkansas over ten years ago.. Grant began collecting agates with his dad, a mining engineer in Arizona. when he was 17. At seventy he is still actively collecting, cutting and selling his agates through his informative website, the agatecollectorsdream. Grant gave the Round Mountain agates the name “Arizona Antique Pink”. The show will open at noon, EST.

This show along with the previous “Night Sky” offering and the coming show of agates collected by Grant of fine Chimney bed agates will delight those collectors who would like to have fine specimens from these 3 major locations.

Here’s wishing you a great summer, happily I’ll be spending mine in Oregon, expect some fine new specimens from that agate wonderland.

Keep rockin’,


Arizona Night Sky Agates

Posted on Updated on

Sunday, the 29th of April an agate offering will open at noon, EST, of the rare Night Sky agates from Mulligan Peak near Clifton, Arizona.

                                                   at:  The Agate Shop

To those familiar with Mulligan Peak agates (also known as Clifton agates) these large purple beauties may come as a surprise. The location was first described in a copy of The Lapidary Journal that came out about fifty years ago by Bessie Simpson and then the locations was lost. The article caught the eye of Grant Curtis who had begun collection on Mulligan Peak when he was 17. Her article gave two clues, that it was near a steep rock face and that there was a camp littered with rusting tin cans there. Grant was on the lookout for these two signs but there are many places up there that meet these conditions and the area is vast. Eventually he found it and at the time I was a regular visitor to his house. Even though it was not a large deposit the remarkable coincidence of all those events led to my obtaining these eleven specimens.

I hope you will be able to join the event,

Chinese ‘Fighting Blood’ Agates Sunday! Begins Noon, Eastern Standard Time, April 22

Posted on Updated on


Sunday can be a quiet day but I’ll do my best to make this one exciting.

Come to to visit my entertaining blog and branch to any of my six ETSY stores. Or go directly to The Agate Shop and the first thing you will see are 25 select Chinese agates.

The famous mines in Hebei, China, were permanently closed over two years ago. Top specimens like these are becoming rare, this is a special moment in agate history. They were discovered only about eight years ago 150 km northwest of Beijing.

An Easter thunderegg hunt

Posted on Updated on

Not every holiday is as enjoyable for adults as it is for the kids so for this Easter I’ve prepared a thunderegg hunt for Easter Day which should provide some adult fun for thunderegg collectors. I added 13 fine Lava Caps to The Thunderegg Shop and I hope you enjoy them.

Remember the list at the top of this page which allows you to enter any of my six shops. I’ve added some nice Condors to The Agate Shop for the banded agate crowd.

I’m looking forward to spending another summer in Oregon. I plan to have an entertaining little travel trailer I named Caboose to abide in or to travel around in this summer, it’s a Casita and very cozy.

I wish you all a good summer and hope your collection gives you and your friends a great place to connect with the beauty of the natural world,
