A Job Well Done Chris! Your friendly demeanor, warm vocal tone, and concise delivery of information made the video feel more like a private tour than a industrial informational. And to The Behind The Scenes Production Crew, here is my thumbs up salute for your work too.
I'm a dude and I love the pink sapphires, especially the deeper magenta tones. I like the yellow ones too. I didn't realise that predominantly (depending on where you get the sapphire) you tend to get a lot of light green, its not quite as pure a lime green as a peridot. It was interesting to see the heat treating. I wondered how they came out that brilliant blue.
I found this video very informative...I never knew the real meaning of heat treating and how the colors can change. not only is this man sexy as hell, but a great speaking voice.... look at his smiles !!! DAMN !!
Thanks for all the information. I am cutting the unheated ones. The small natural light blue ones cut nice. But now if I have a sapphire that may need some help I think I will send to get treated. But if I can keep the natural I will.
Learning about gemstones is a whole another level in a whole another world it just keep get deeper and deeper, but I love it I been reseaching hard I read a book call "Gems of the World" a copyright of (2008) that book is 11 years old by Cally Oldershaw once in 2017 once in 2018, and twice early in the year of 2019 been researching hard since 2017-until now I'm striving for a GIA that is right up my alley. Oh I'm going I believe that The Most High will make ever come to life me taking up gemology...this is my future career.
My level of anxiety when he was taking that stack of crucibles out of the furnace was through the roof, I had this mental image of the entire stack toppling over, spilling the entire lot on the floor and ruining their entire careful inventory process. 😬I am amazed that they have such a precarious step with SO much inventory.
I have a friend whom just moved close to Gem Mtn. Plan on heading there on my cross country mining trip. Might take me awhile to get there but it's on my list.
You are a great teacher, and a gemologist to me, and I fully enjoyed your vid, you explained everything in detail and it made it easier for me to understand how to segregation hues of Sapphires for a heat treatment process . fancy Montana green sapphires for heat treating is wonderfull! How do I get in touch with you for more informatiin..? Thanks! 💎💎💎💎💎💎💎💎💎💎💎 Thanks!!
Good morning friend, can I ask you a question? on a montana sapphire a bicolor Hot pink of 20 carats what would be its value of this stone. I am a collector and I have some Gems saved but how is the crisis today. I see myself in need of selling my Gems so I kept them in difficult times and I think the time has come to do it
I once lived in Montana and my friend Corky was an old rock hound and gave me 2 very large sapphire/corrundum specimens. Unfortunately stolen from me some years ago. The idea of the U.S. producing valuable sapphires is intriguing and I hope that the world will once truely value the Montana gemstones it rightly deserves. It pains me that so many people dont see gemstones as valuable as they once did. At least in my opinion. I mean just the thought of how long and the so very unique and rare circumstances that it takes for thier creation is enough for me to see great value in sapphires. I'm wearing 2 small dark blue ones now as I'm typing this comment and thanks to videos like this...I value them just that much more. Great video. Keep em coming.
I have a 5 carat that is natural but is dark blue, l wonder if heating it would make it better looking, and I'm in Australia can I send you single stone for treatment?
correct me if I'm wrong I think if you change the shape of the crucible ( mesh shaped or the base of the crucible has holes), I think this will change the heat current inside the furnace. and will affect the color saturation. the 1/3 of your unsaturated stones will decline.
GIA does not heat treat gemstones. For specific details about the process, we suggest you contact Gem Mountain, the company that demonstrated the process in the video. Published information, such as the book The Heat Treatment of Ruby & Sapphire: Alchemy & Science by Ted Themelis (3rd Edition, 2015), might also be helpful to you
That can help as my associate learned back in 1985.......but not so relative to the heat but more relative to the specific Gas atmosphere contacting each stone in a more effective manner...and it did make a difference ...cheers
Hi John: GIA does not treat gemstones. You might read the book The Heat Treatment of Ruby & Sapphire: Alchemy & Science by Ted Themelis (3rd Edition, 2015) for more information. Hope this helps.
I LOL'd when he said the pink color is most desirable of the "female species". Who talks like this? Anyway good video, however I would have loved to see more close up shots of the stones, particularly a before and after shot of the heated stones.
men who haven't been indoctrinated with the liberal gobbledegoop of the current era....I bet you either grew up in an area like san Francisco or are under 35 years old...?on target?
@@douglashanlon1975 Since when is it liberal gobbledegoop knowing that women are not a separate species? Gobbledegoop, in my opinion, is the phrase female species, as that's not a thing, females of the species would make sense, but women would make even more. Unless he means females of any species, humans, horses, tigers etc. or he's referring to any species comprised exclusively of females, preferring pink sapphires.
Hello , sir I'm from Libya arabic i found pieces from black carbonado diamond like Kirloff black diamond and too i found rough pinksh diamond in kemberlite in Libya , one peice weight 《40》 carat but it's need heat for become very good. I need your help me for teasting and polishing my stones and buyer in american markets
Hi KMP Gnanasiri: For information about heat treating sapphires and rubies, as well as other gems, please see our article An Introduction to Treatments: www.gia.edu/gem-treatment
Official GIA Channel Hello, Thanks for the reply. According to the information. There is only heating as a solution. As it says low heating removes silks. But I want to know how to clean milky non-transparent Sapphire (including Rubies) with good color, without making it colorless and turn it in to a clean transparent stone, below one is an example pre-formed ruby
Well i like natural .mother nature is the best without altercations...whom ever stumbled across this process would be an interesting read..kudos to the process though. How much does it cost for the treatment 2024 year..this video is older .and if you were still giving a blue ting to one of them ..i like natural..but it would be fine too! Cheers
It would have been nice if the person filming this would have done more close-ups on the stones, especially those the gemologist was pointing out that had particular features. Shoddy camera work.
Considered inert and none reactive to the mineral itself which is Alumina Oxide ( Corundum ) but crystallized .... With some source material and more so than other sources you will observe the Alumina Oxide crucibles or dishes or plates or the platform, so to speak, used to contain the colored corundum absorb some of the color from the corundum that you are burning.......so a white or cream colored Alumina ceramic dish or crucible, is stained Blue or Red or Pink, for example, after burning the Blue Sapphires or Pink Sapphires or Rubies or Purple Sapphires or Yellow sapphires...like that ..Cheers
Hi huskyfluffy: GIA does not sell gemstones. We are nonprofit research and education institute, and provide these videos for educational purposes only.
does not heat treating changes the molecular value of the stone? then, is it at all ok for wearing as a gem stone for astrological effects? just for money is this all done?????? money money money??
No, it increase the value and the reason the Rubies and Sapphires are heated.....from no color or very little color and sleepy, to better color and or better transparency after heating, then makes the stone worth more......
Meet these Gentlemen! They believe they know gemstones. Without scientific tools they are mere laymen.I know wonderful people who can really pick out a real gemstone out of thousands of color zirconia by naked eye.
So.....Diamonds and Sapphires are priced based on 3 factors. First, the jewelry business puts an irrational emphasis on 'natural' vs lab created. Second, the clarity or amount of flaws within. Third, the coloring of the stone. NOW.... I have never subscribed to 1 as that is nonsense... but the color & clarity are very important. AND, if you factor in that lab grown stones are typically flawless, and now we see that the color is also artificially engineered.... why are people still buying the flawed, uncolored, dug up stones ? In my opinion, if even the 'natural' stones are artificially colored, then the whole jewelry industry is a bunch of hypocrites trying to sell to anyone gullible enough to buy them. I have purchased many diamond and sapphire rings in my life. None of them have ever been over $100 and I laugh when someone shows me their 'real' diamond ring that they paid thousands for... and I have to pull out my magnifying glass to see it.
Mother Nature is already perfect how can we perfect stones that are already perfect. I don't think we should be Heat Treating stones, I think it should be against the law to make synthetics or lab-created stones
Way to destroy the value... might as well facet some pretty glass. Heat treated sapphires become brittle. Modern cell phone glass is a form of treated sapphire - shatters into glassy dust when fractured. "In very short detail, an untreated sapphire is one that has been taken from the ground in which it came and faceted. Nothing at all was done to the stone to alter the natural beauty which only the earth created naturally. These sapphires are exceptionally more rare and valuable. For this reason, sapphires are extraordinarily unique from one to the next. No two are exactly the same; rare and unusual sapphires are almost irreplaceable, even one that is only 1 or 2 carats in size." ~ copied from a sapphire education source. Sure, some people may appreciate the added properties and pay extra to have those qualities. However the glory days of sapphire mining is long, long gone. That being said - treating a sapphire is like stealing the last few dollars in earths sapphire account. I mine, cut, and sell natural Missouri river sapphires. Some of them that is. "A mine is a hole in the ground owned by a liar. ~Mark Clemens / Samuel Twain
Think what you may....Meantime the over whelming majority of Colored Corundum recovered from any mining location is low grade material relative to how it looks in its natural state, in comparison to the small percent that is already looking attractive and considered as high quality "looking" and of higher value.....The overwhelming majority of your Missouri river sapphires are pale, near colorless sapphires that are hardly appealing in their natural state....That being the case, then the material can be heated and a notable percent develop better Blue color and better Yellow color and some a nice yellow / orange color and some turn pleasant Violet color and even a nice saturated purple color sometimes and sometimes some turn a nice Padparadcha color from an original pink /slightly brownish color .......Because I know as I have Heat Treated the material before.....and ...because now, people know that it can be heat treated then they pay more for the rough than they would normally pay if it could not be heated or considered not heat treatable after trying for years and years to figure out how to develop color in otherwise near colorless, low value sapphire rough.....Now that they know it can be heated and the material reacts reasonably well to heating and therefore becomes more valuable, then some people will pay "a price" and relative to the known results after heating and more so as compared to if the material did not treat well enough or did not respond at all to heat treatment.....With the right equipment and heating procedures the Montana material is now considered "usable".....So, in effect, you should not be lamenting and criticizing Heat Treatment because your Sapphires are now more valuable because of heat treating........understand ..........Cheers

Probably has, because he said "we're safe" when he had it on the table the way he wanted it lol

hi
Using impervious aluminum oxide crucible to heat sapphires made up of aluminum oxide. Kind of ironic don't ya think?
Considered inert and none reactive to the mineral itself which is Alumina Oxide ( Corundum ) but crystallized .... With some source material and more so than other sources you will observe the Alumina Oxide crucibles or dishes or plates or the platform, so to speak, used to contain the colored corundum absorb some of the color from the corundum that you are burning.......so a white or cream colored Alumina ceramic dish or crucible, is stained Blue or Red or Pink, for example, after burning the Blue Sapphires or Pink Sapphires or Rubies or Purple Sapphires or Yellow sapphires...like that ..Cheers
