Gemology Journey

If you found a sapphire or a ruby in a river, would you know how to recognize them?

If the answer is no, then this video is for you, because today I'm going to teach you how to identify sapphires and rubies, should you find one lying around.
Gemstones require a little more attention to spot.

Many of those jagged-looking stones shown in this video are not rubies, but are rhodolite garnets that occur sometimes in alluvial gravels alongside the corundum. Rubies and sapphires have a completely different cleavage and luster. I'm guessing a number of these were screened at the Mason Mountain mine in Franklin, NC, as the garnet looks identical to the ones found there. It is true that many gemstones can be found in granite pegmatites, but corundums are rarely one of them.
And I think the rest of the inaccuracies were covered by Darknimbus3's comments below. With matters of science, accuracy is important.

Ok there is a lot to correct here, particularly in terms of identifying signs for rubies/sapphires.

1) Quartz is not necessarily an indicator! Quartz is almost in every stream. As a matter of fact, in the primary deposit, quartz will not be found with corundum, as corundum forms in silica-poor rocks. This is because any silica will absorb the aluminum to create alumina-silicates like feldspar and mica.

2) Shale is NOT an associate with corundum. Shale is a sedimentary rock. Corundums do not form in sedimentary rock, and if they are found in sedimentary rock it would most likely be a conglomerate. Also that “mica schist” example in 3:20 is not actually schist- it’s a mica bearing pegmatite. Speaking of which….

3) Most pegmatite is also NOT an indicator for corundum. There is sapphire-bearing pegmatite, however that is very VERY rare, and those pegmatites have no quartz. Also most pegmatites, being granitic in nature are silica rich, which goes back to my point #1

4) It’s spelled “gneiss” and “gneisses” respectively. Also it has to be the correct gneiss. Gneiss with quartz = no corundum.

5) 4:05 is spelled “zoisite” and pronounced “zow-uh-site”. Also that green ruby-zoisite is endemic to Tanzania- it’s not found anywhere else in the world. So unless you live in Tanzania, that tip is useless. Elsewhere, you’re more likely to find ruby with fuchsite.

6) 4:21 No (in the vast majority of cases), maybe, and definitely NO. There are very rare volcanics that have corundum xenocrysts, but that is extremely rare. For example, there is basalt bearing sapphire xenocrysts in Burma, and Montana sapphires come as xenocrysts from a lamprophyre. However, other than that, forget about it. Yes, certain marbles may have corundum. This will depend on the temperature and pressure conditions as well as other regional factors. As for granite, granite = quartz-rich, which goes back to point #1. Some syenites or diorites, however may bear corundum. Syenites and diorites look like granites, but are silica-poor and tend to be feldspar-rich.

No mention of heat treating sapphires. If X-amount of heat is applied to a sapphire the color usually changes. It also sets that color. A heated sapphire, in, for example, a ring, that has been taken in for repairs, can withstand the heat needed for the repair without changing the color of the sapphire. A non-heat treated sapphire must either be pulled or protected, from the heat needed for the repair or the sapphire will change color. And the owner will be very upset. When you find a sapphire that appears to show a certain color, after heat treating, can become a completely different color. If you choose to not heat treat your finds it is a good idea to tell any jeweler working on it that it is a non-heat treated stone so they know to protect it. There by avoiding an unwanted color change. Sapphires, like diamonds, can take the direct heat of a torch.

My brother was a goldsmith and a client gave him a large glass tube full of tiny rubies as a gift. They were worthless for jewellery but he spilled them out in his glass case and displayed his pieces on them.

[KimCrisp]

I love being by the water. I love finding beautiful colored and shaped rocks. Heart rocks.

[itzzzsss]

So basically, just find an odd looking beat up gummy bear in streams, rivers, and lakes. Beaches too

[TheFiown]

As a kid I found amethysts and citrines in the streams flowing down from the mountain.

Some rather large & very beautiful Garnets are often found on the River Thames in London. Mudlarkers find them there while searching for other treasures. Its believed these Garnets came from India & Asia possibly as simple Ballast in old ships.

"keep an eye out for these 17 minerals in your area and you may find gems" 😵‍💫

Its funny, I started out hunting for arrowheads, after 40 years I started finding facial effigies on not only flint points, but gemstone, limestone, basalt etc… almost to the piece, the gemstones that I find, have an ancient peoples effigy on it. You can hardly find one that hasnt already been used for an effigy stone… Primitive Rock Art. It opened up a whole new passion for me, and most of them I refrain to cut on.

"...including the rivers in the regions where you live" I'm in Florida, dude. Nothing here but limerock, shells and sharksteeth😂 no hard stones😭

[foolishprodigy]

loved rock hunting when I was a kid. my dad pointed out flint stones to me and I would collect some every time I went out. at some point I had so many I decided to go to the place I found a lot of them and scattered them around so that hopefully someone one day with find them

[JohnWedow]

As a 73 yr old i have spent the last two summers in Montana Grizzly infested back country . Just now i realized the ones i threw back in the creek . Live and learn .

[RoachdoggJR]

I've always enjoyed collecting small stones and minerals near river and creek beds. Now, thanks to this video, i know what to look out for when collecting.

[shanefowkes]

If been called a human metal dectector, every time I'm in a new area of never been I'll always find eaither coins jewlery or even metal buttons

You have to be careful with Mica, as it can be mixed with or along side of Asbestos.

Sadly, where I live, most minerals are not common, as the glaciers ground up the land and left limestone and gypsum behind as well as tons and tons of sand and clay, with huge granite boulders mixed in.

[jordanrock]

Yes, I can. Maintenance at my complex dumps piles of rocks to use for foundation, and I find a ton of precious stones. Good times.

Lots of mica shist and milky quartz in my yard in Underhill, VT (valley close to Stowe) that comes up when I pull weeds. I have found 3 rocks that I haven't identified. 1 is solid black like an onyx. 2.The other is a half circle shaped opaque with white/ clearish color and areas that are pink to orange, and a pice broke off of it with strange fracture at the broken area. 3. Is a rusty rock with a smooth creamy pink almost like a corral growth on the rock. I have no clue what the 3 rocks are.😊

I have been going to montana for over 10 yrs and mine /hunt the sapphires there..found and had jeweled over 100 cts of various colors purples pinks yellows greens blues its amazing how many colors there are. missouri river is magical
