Lovely little specimen from Elmwood, TN. The crystal on the right is about 1 inch cubed.

WOW!
Thanks to all for the Great rocks and landscape photos!
The Albatross! I want to attend the Tucson gem & mineral show this year, but no reservations or firm plans are in place. I'll post if I know more about our plans.
I'm currently working hard at photographing coral formations near Maui. The darn fish keep getting in my way.

Epidote is a fairly hard (6-7) Silicate mineral that is commonly found in contact rocks. Although some consider it a semi-precious stone, it is mainly of interest to collectors. It occurs in mostly dark greenish colors & is somewhat to very translucent.
I’ve found it at several locations in Idaho, but most of my specimens are from the south end of the Seven Devils mountains, high above Hell’s Canyon of the Snake River. Epidote occurs in old copper mines there & is often found with garnets, hematite, & copper minerals. It’s nice country for mineral collecting with great views & mostly open terrain to hike.

It looks about 95% certain that Heidi & I are going to be in Tucson for the last week of the Gem & Mineral Show. We have a room booked for nights of Feb. 9-11th.
Anyone else going to the Show then? We'd enjoy doing a rocky Meet & Greet!

Looks like I will just miss you, going for a long weekend returning to Flag on Monday the 8th…
Any suggestions on cleaning andradite? I've tried Muriatic acid, maybe didn't soak it long enough? (Trying to remove yellow film)

Albatross: Sorry we are going to miss you. We may try to stop by Flag & visit on our way home, depending on the weather.
If those yellowish stains are iron stains, I've got the super-duper, reasonably non-toxic, but somewhat complicated way to remove them.
I used it with great success to clean iron stains off both Fluorite & quartz crystals last summer.
I am not going to take on the liability of posting the two pages of info on the internet, but will email you the info as a word doc.
Folks can find it, as I did, by searching for Mineral cleaning info & add The Waller solution to the search terms.
The "Waller" Solution
This method of mineral cleaning was first introduced as a simple method of cleaning iron stain from minerals. Further research reveals different methods of using the basic solution.
It works by combining Super Iron Out, Baking soda, & citric acid in water. Super Iron Out is available at Home Depot & I bought my citric acid on Amazon. Be sure the Super Iron Out you buy does NOT have acid in it, since they use the same name for several products. The ingredient you want is Sodium Dithionite

Heidi & I made a eight day road-trip down to Tucson for the Gem & Mineral Show, then pushed on to Patagonia for a two-day visit to some old classmates.
We toured the best hotel venues to buy mineral specimens from dealers on our first day, then attended the 62nd annual Tucson Gem & Mineral Show in the Convention Center the next day.
The Convention Center had a lot of special exhibits of collections & spectacular mineral specimens were everywhere. Here's some that we captured with our camera.
There were lots of displays of large amethyst quartz crystals from geodes found in Uraguay.
Some of the amethyst geodes were huge. This one obviously called out to me. Unfortunately security arrived before I could complete the boulder problem.
Gold! There was a lot of gold on exhibit. This piece was about 10" wide and was mostly fused gold crystals.
