Is it acanthite?

I just found these videos - this is the kind of resource I've been searching for for years! Thank you!

I added a little if this is true olivine which is in crystal form has higher silica and low nickel content.

Found brown rock in parking lot. Felt like sandpaper, layers peeled off like Pillsbury biscuit. Of course I peeled the layers and threw it away, so no pics. What was it?

I found one similar to what you have I did the streak test not black it just carved in the tile and it has like a diamond in it and the density is 40.0 and it weighs 114.5 g and ct is 572.5 /4.04 oz to is 9.81 /gn 1766 It's black it sticks to a magnet?

Instagram anda.. Thx

How to tell difference between galena and silver sulphide?

"and really, color is what does it for the amphiboles." That could not be more true in my world! I've been collecting nephrite in Wyoming for decades, and color is what makes the difference between the best emerald and apple green jade and a lump of uninspiring olive or sage green.

No danger in displaying them as-is. In a small, plastic case to prevent dust; The fibrous minerals have a beauty all their own.

Thank you for your video series. I've watched a lot and find yours is one of the best

Have a calcite

Any mineral with density < 1 ?

Galena ?

Thank you. Lonsdaleite necheral Diamond par caret HOW much sir

This was super informative and easy to follow. Thank you for sharing your knowledge 😊

Spessartine is best garnet..❤

I've found a lot of Olivene here in Wyoming.

It looks like Chrysoprase to me

Is it quartz chalcedony?

i have chalcopyrite and i want to know if it real

Holy cow that’s a cancer cocktail! How could you not mention asbestos?

How to dissolve graphite? Any process ?

Great information. Your videos short, direct to the point. Subscribed! If you can also do the mix specimen samples as well. Or same crystal around the world example amethyst. How and why different colors, which is more preferable, different qualities. Example how to know AAA quality and museum quality pieces.

Thankyouvary much

I just found an area with lots of garnets 😊 I think there almandine but not sure

Thank you for that, it's helped greatly :):).

Good speaking voice, thanks for sharing your knowledge

If you run it through a electro magnet will it hold onto its magnetism as in would even temporarily become a magnet in other words can you make a permanent magnet out of magnetite ?

Great information, I’ve been finding some pieces around on hikes but none like that faceted one! I found a nice semi flat piece and want to carve or shape a pendant some how..any suggestions?

Pourquoi en anglais On est en France

I love your videos thank you.

i love them all just dug some perthite from old Perth quarry

This seems like quite a good mineral to carve high detail microcarvings on due to the low hardness and apparent lack of chipping flaking. Do you know of any other low hardness minerals that would be good for this sort of work? Thanks for the informative video!

It's an experiment to see the reaction of calcite, right? calcium carbonate

Excellent 👍 thank you

Thanks for the info, my friends house is made of the clear stuff

Plutonium... no, no! Asbestos 🤓 ...nailed it. That time that student never came back after midterms .

Thank you, you make sense

Nice crystal of pyrite - I only ever found cubes! A marcasite sample had me fooled for years...

There is also the black variety known as "blackjack" and has an adamantine lustre.

Very helpful video - thanks! It's also crumbly and often smells slightly of sulphur, more so than pyrite. The crystal form is the key.

Ola.Estou curiosa para saber se achei uma Amazonita?Encontrei numa praia uma pedra verde com uma espécie de capa brilhosa semelhante a está cor de salmão que Vce mostrou.Mas a pedra tem formato triangular e uma base piramidal com um acabamento em zigzag na textura Toda ela reflete brilho prateado cinza .Mas parece ser rodeada por linha de crescimento do cristal ou então trata-se de fedspato? Gostaria muito de lhe mostrar em vídeo. Aqui uns dizem que é Amazonita.Outros dizem que não por conta da textura da pedra que difere da pedra Amazonita. Vce tem como ajudar?

Halite?

Wow a YT video that is science based and not some sales pitch bs or esotheric delusion.

This video is very helpful for me ❤

Do your sample fluoresce?
