Gemologists Reveal Their Favorite Specimens | Gems of the SGR

i got a box in a box i lovingly dubbed this piece the hubcap i love that piece oh my gosh as you guys can see this piece is just sparkles coming off here absolutely incredible this is actually natural these pieces are so sought after it's really pretty guys [Music] this is like the first time i think we've set at this table together this is the first time here today we are going to talk about the sgr so if you guys don't know what the sgr is it is a three volume set that we have produced in-house at jtv that is all about minerals and gemstones and their identification it's got lore it's got all these interesting stories it has absolutely fantastic images it was the original brainchild of one of our founders jerry sisk who unfortunately passed away but this has been a massive labor of love to bring his dream to fruition i use it every day it's just an absolute wealth of information we both did different editorial contributions to the book the third volume is a catalog of just all these absolutely beautiful images and we're going to show you some of the actual pieces themselves did you bring anything i brought something i did i did bring things let's look at some things that are actually in the book okay so we have a not so standard box i want you to read the clue that's not a clue this is the clue this is a pretty big clue right here don't judge a rock by its box oh gosh it could be anything out of the book that one no not that one this is an absolutely spectacular ammolite from the bearpaw formation in canada oh yeah i lovingly dubbed this piece the hubcap this piece is one of my favorites for obvious reasons it is gigantic as a geologist it is really cool to see a piece like this actually come out of the ground in well one piece these little amyloids are from canada so you can get ammonites that have amyloid which is the gemstone that extend down into utah a little bit but the finest and the best quality and the only commercial source is from the bearpaw formation so this is actually caused by light interfering with the aragonite structure i think almost like an oil slick the way uh light scatters and gives a rainbow on an oil stick it's the same thing like going in and out of different layers of material what's really crazy about these guys this particular little critter existed around 75 to 66 million years ago just like this just a big floating shell yeah well they had a little these guys are found in shale which is a type of rock and it's really flaky it's really fragile and they're usually coated in either ciderite or pyrite that's not what that one's coated in now though no this is actually coated in car varnish to keep it from being damaged by uv light and to keep it from flaking these shells can be as thin as like 0.2 millimeter i mean they're they're extremely thin and extremely fragile some of you may notice that this piece actually wants to sit like this there's a story there so if you guys notice the image it's sitting let me see up like this so we literally took a piece of fishing line a little clip on the back of it two poles and we situated a little clip just barely holding this up and then a tiny little piece of velcro tiny tiny piece of velcro the photographer was like don't move we held our breath and we literally stood on either side of it like this like literally like this so when you see this picture just picture both elizabeth and i on either side of it out of the frame of the picture because that's right where we are ready to pounce on this thing if it shifts a micron i got a gray hair or two from that one i think okay you can look now whoa and now it's time for you to get a clue this was one of the first pieces i acquired when we hatched the plan for volume three there's a clue in there there's an actual clue in there hatched so it is i believe the opal egg ready one of the amazing things with doing the photography for the systemology reference is we wanted to make sure to show everything to its best effect we were able to get the photo in so close that we can show it to you in much greater detail than you can really see with it in hand get this off of here it's so cute this one is what we call a boulder matrix opal you have solid opals which are opal top to bottom you have bolder opals and a bolder opal is like a natural double you have a thin layer of opal on top of a layer of the natural matrix this is called a boulder matrix opal because the opal is actually inner grown into the matrix itself so it's not just one flat layer over the opal there's opal throughout the entire stone from one side to the other going all through the middle and out the sides sorry good thing it's not a real egg just it's incredible it's got color every every bit of the rainbow and that's that's one of the quality factors you always look for in opal is you want to have a full range of color if possible and you want those colors to be as vivid as possible it's just spectacular all right what you got for me next okay we're going back to the traditional boxes guys i'm ready take out your next clue i know you're a jolio chap so this is your cup of tea okay that's gotta be from england although my accent is very obviously not i'm calling my shot boom yeah let's see i love these pieces yes this is just an absolutely beautiful fluorite specimen from roger england this forest green color is extremely famous from there this mine is actually a 19th century quarry they were exploring and they actually discovered some of these fluorites and it became for a while the only mine in england that was exclusively mined for the production of mineral specimens absolutely beautiful specimens they also make some beautiful beautiful gemstones when cut very rarely you find them cut but when you do one of my favorite things about these is their shape i love that you get these really awesome they're called penetration twins in these crystals and not only that and let's see if i can get this right there we go so they have incredibly intense fluorescence see if it'll actually show more of the the natural daylight there we go so that would be more what you see if you take it outside so you get this pretty blushing blue color and what's really cool this piece came from the bluebell pocket the reason it was called the blue belt pocket is this intense blue fluorescence and you can stand with this piece like right in an open doorway and it's just vivid green like that and then boom you walk outside and that's what you get like immediately it's absolutely amazing okay also the plastic this is one of my horrible horrible plays on words also the plastic i don't know i really don't know i had several it's really really bad pun oh lucite [Laughter] oh my god also the plastic and the lucite so it is this picture i got a box in a box we haven't even littler box oh is it sodalite oh it's a soda light there you go i knew i recognized it my old guy right there figure out how this works the hinges on one side yeah i just don't i don't want to hurt it it looks old and valuable so if you guys can't see it is 1090 again we've got a very very small thumbnail sized piece thumbnail is basically under three centimeters here you go guys there's the visual thumbnail thumbnail what's special about it or what what is renowned for is that it's trichroic and what that means is you can see the stone as three different colors depending on the direction in which you view it now when light goes into a stone if it's transparent it'll bounce around and it'll come back out in another direction so i gave it to jim wells photographer and that was the super challenge that he had with photographing this was to be able to show the yellow the orange and the green all in one direction when photographing it and he had so many lights on this thing just to make sure that he got the light of the correct color bouncing out the front of it to show it was just amazing but this one this one was uh this one was super challenging just to even get a representation of and i did at long last find a crystal don't find yourself i totally did i was going to see if i couldn't show it directionally so i can't tell if you guys can see the orange oh i can and the green i mean i can see it right now a lot of people think it's actually a color change or a color shift stone now it's completely different property it doesn't change because of the quality of the light it just changes color depending on the viewing direction do you have another clue for me i do am i going to have to speak in a silly voice to read it no okay there's no need for extra glitter oh boom that just jumped out at me i'm calling this one oh yeah i love that piece oh my gosh it looks like glitter okay but it's not glitter so this is calcapyrite on dog toothed calcite but so as you guys can see this piece is just coming off here absolutely incredible so no need to add extra glitter but the funny story with this piece so this is a piece that came out of china this is actually very natural but unfortunately a lot of times what happens is people sometimes think things need a little extra something for people to buy them so somebody had the brilliant idea to actually take glue and glitter and put it on this and so the company that we ended up buying it from had to sit there with a microscope and pick it off of it the reason that these pieces are so sought after and so just absolutely beloved in the mineral community is because of this beautiful iridescence that you get on these jersey calcapyrites so the rainbow colors are actually caused by a reaction with acids in the fluids oh okay so it's not like an oxidation process so it's actually a tarnish but it makes this beautiful effect it's the minerals combined with something in the acid to create a little layer that's causing the iridescence yeah and you guys can actually see oh yeah where it was cut out of the rock that it came from in the mine i have one last piece for you okay with arms open wide actually with arms wide open oh my gosh that song is going to be stuck in my head all day okay i think i know which one this is this little guy that is correct this is our little guy right there one of the most iconic gemstones is sapphire gem crystals are hard to come by because they are so valuable and of course really fine gemstone crystals often get cut even if they would make nice specimens this is one of the first mineral specimens that i ever bought had no clue as to what i was looking at at the time i just knew i really liked it and i thought it was super super cool which is always the best reason to get a specimen or a gym or a piece of jewelry for your collection is because you like it and you're going to enjoy it this particular piece is a sapphire crystal and it has two twin crystals coming off of it it just looks like it's it's just ready for a hug a very very small small specimen here but we're able to use the book to show it to you in immaculate detail all right so you've got yours i've got mine what is the one that you want to take a closer look at on the table i like this one oh okay i just i love that the more you turn it the prettier it gets and just all that beautiful play of color it looks like somebody put glitter in a rock it's just so pretty and for me it would definitely be this one because you know like i said i love fluorite it's one of my favorites if you get it under an intense bike light you're going to get like crazy fluorescence there but yeah this is just really that daylight inside outside inside outside oh i just love it [Music] [Music] all right folks thanks for being with us today and i hope you enjoyed all the specimens that we brought
