According to the article, "The only way to relieve yourself of this is to give it back," she said. I know as I get older it is sometimes harder to relieve myself. I never thought of giving away Jade as the solution for that. They could end up with blocks of Jade from all over the world donated by men with aging prostates.

Learn your mineral physical properties, these can be found in most any mineral book or college minerlogy text. A rocks is defined as being composed of 1 or more minerals, If you want to learn about rocks then select a college petrology (study of rocks) textbook. Gemstones are a sub category of these two. Some suggested books: Dana's Manual of Mineralology, Hurlbut, Cornelius S., Jr. Ph. D., ISBN 0-471-42225-8 A Field Guide to Rocks and Minerals, Pough, Frederick H. Rocks and Minerals, A Golden Nature Guide, Zim, Herbert S. <= less technical but drawings are good and info is good beginner guide
If you are an old fart I have heard that the local university will allow you to audit a class with permission. Not sure if it is true but if you could audit (no college credit- No cost) a class on minerology or historical geology these will also help. When I retire I was going to check that out. Distance learning is not good for minerals. you have to touch to study.

ethansco I was not sure what a "Lortone Gem Sparkle 3A NR1" was since it is not in their current catalog. What I found on e-bay is a 40 year old tumbler with that designation. Lortone 3A tumblers have been two different shades of blue in the last 30+ years my original Lortone 3A was indeed a 3A NR1. That was in 1972. they have a greenish paint job. my age estimate is based on the color the tumbler is painted. check out: cdn.shopify.com/s/files/1/1783/4633/t/4/assets/3A_Tumbler_Instructions.pdf?v=1365396662230421983the lortone motor has a fan and there is a pulley built into the fan. It is one piece. On that link it is listed as part H 001-100 Motor Pulley With Fan

the # 3 the red looks like rhyolite, top white like quartz, the #1 dendritic is it porous or solid, #2 looks more like wood to me but maybe healed fractures and brecciated

BTW #13 looks like it could be travertine. check hardness if H=3 then don't tumble

assume tigereye is h=7. you are right tumble H=7 together in 3# drums, if diameter is greater like a 6 or 12# drum, tumble quartz and tigereye together. agate and jasper together in separate load. H=6 together etc

I would say the fracture is subconcoidal and mildly waxy. I would call that agate not chert but you pay your money and make your choice we are diagnosing from a picture. the color is not as bright as I would expect chrysoprase to be but it could be mtorolite with the color coming from chromium. Normally mtorolite has a pattern which can be seen when sawed where chrysoprase has no pattern. I would typically expect chert to be more opaque.

#3 looks like Coprolite or possibly Mozarkite #4 I think your guess is right #6 possibly clay canyon Jasper #7 possibly indio moss #8 Vaquilla Agate #9 mex lace based on what I see the distinctive part that defines laguna lace is wider banding

I see the title that I missed earlier. I had to replace the rubber inner gaskets on 12# drums I purchased used but have never come close to wearing out a drum even though I use 46/70 grit.

When I was in college I borrowed a bicycle from a friend for a 5 mile trek to a local mine. This bike has a small racing seat and I picked up about 50# of rock and put them in my backpack. Needless to say when I got back I could hardly walk for a week. I learned "don't pick up rocks when cycling."

Mica was high graded out of museums during WWII to make electrical insulation for electronics. Non-conductive

molydbenite has a black streak and mica has a white streak. they are easy to tell a part.
