Faceting gemstones: cutting a huge gem 2
Вставка
- Опубліковано 18 чер 2024
- Watch as i cut my biggest gemstone yet. Im cutting boro silicate glass in a round shape. The finished gem is 368 carats and 48 mm in diameter. Warning: this material could be hazardous to your health when being cut .
The cutting laps i used were as follows 100, 260, 360, 600, 1200 grit plated diamond laps. The prepolish laps were lightning lap resin 3000, and 8000 grits. I also used a zinc gearloose lap with 3000 diamond. The polish laps used were lightning lap cerium oxide and aluminum oxide laps, and gearloose creamway lap.
being this material is glass and a hardness of 5.5, i had some problems in getting scratch free polished facets at times.

Awesome cut, Brent. Viewers who don't cut may not recognize just how hard that was. I was riveted to the video as you brought that one "home". Thanks much!
Hi john, and thanks .Yes this was difficult just for the size aspect of it. I spent about a month off and on working on it. After i finished and looked it over i would have been better off i think to have cut it in a portuguese cut.
Thank you! Very nice work.
I'm truly inspired from your videos thank you!!!
Beautiful
Thanks very much , its a lot of fun for me.
Great video! What a piece of art!
Thanks very much.
Your jazz music playing and watching you grind the stone is so relaxing. Love it 👍
thanks very much, ive had some complaints about it on other videos.
Gorgeous cut.
As Usual🙏Ur R Indeed A Master Craftsman in Faceting👌❤️I could Hardly Believe My Eyes to C the Magnificent Transformation Of A Round Crystal like Ball Transform intoA JUICIEST JUICY GEMSTONE QUALITY CRYSTAL! Almost looked like A Priceless Cut Fancy EMRALD! BRAVO! ❤
Came out beautiful
Omg this is so beautiful ,looks so rick ,the colour has come out beautifully ,very clever ,I did not realise you could cut something as big as a small crystal ball ..Beautiful 😀
Tanks very much, just about anything can be cut and polished , the size is the liming factor and this one is close to the max. The softer materials are the harder ones to polish.
You are an amazing and unique person like ur job I really appreciate ur work man ... and I really loved that gem
Thanks very much.
Hello sir
Beautiful piece and original stone as very beautiful work

Thanks very much.
I'm a new subscriber but I have been watching your videos. Everything I have seen has been absolutely beautiful. You are most talented and a joy to watch. UA-cam is very therapeutic. Thank you for the contribution of your skill and talent.
Hi larry and thanks for subscribing and watching.
A k9 crystal cost only 15$ already cutted into huge gem, make it truly priceless and mesmerising. The finished product look like huge emerald with utmost higher percentages of clarity. Good job sir!😎
Thanks very much.
Wow. Very nice. Thanks for the close video and clear steps you took. I was thinking it would make a pretty cool shiftier knob. Love the color. Lets hope green lantern doesn't see this. Lol
Thanks for watching.
Nice work that is absolutely stunning.
Thanks very much.
Woooowwwzers man, that thing shines! 💎
Thanks, i sold that stone pretty fast.
Nice, great job. HUGE!
Thanks.
Wow. It is another beautiful piece of art that has been created by you. Excellent job. Congratulations, it could you lots of time and effort.
Thank you very much.
Hi. I understand that is not a correct question from American culture point of view but if you forgive I will dare to ask you how much will this piece of art cost now?
@@vectorv750 It is unknown what it could be worth now.
Nice bedroom door handle for mr.Bezos.

Hocam çok zaman ve emek vermişsiniz elinizesaglik...saygılar
It's so beautiful. 😊
Thanks very much.
Hello, what do you use for polishing?
Thanks you
Wow that's a whooper! Polishing must have been tedious. I'm wonder where you got your splash guard 3D print? I'm tried of bulldog clipping my splash guard for girdle cuts and I'm ready to chop it up.
Hello, yes polishing and cutting the table was a real bear, it took around 4 to 4.5 hours total. I thought i would never finish the polishing.
the splash guard gate is from a faceter named terry gump, here is his email: tfg.lapidary@gmail.com. Thanks for watching.
I would love to see what faceted non-transparent rocks would look like. Things like marble, granite, obsidian etc...
They look nice , i have never done one myself.
Wonderful work.
Thanks very much.
wow you've got some patience. I get bored cutting stones over 10 carats. I would like to cut a quartz big enough for a walking stick knob though
Thanks, yes my patience was tested on this one, total cutting time was 36.5 hours.
Bela obra de arte, espetacular.
obrigado
You should make a stand that can fit around the lantern/or lantern can rest in between and get another scaple. To rotate between hot and cooled blades
thanks for the suggestion, i also had another suggestion using a soldering iron to melt the glue away.
Such a beautiful stone. Reminds me of my birthstone. Peridot
Yeah this is clearly a scam ran by one dude and two accounts. People please don’t listen to these two ⬆️
Amazing sir
beautiful!
Thanks very much.
Very informative :)
Hey! great job! quick question, where did you get the sphere from?
It was either from ebay or amazon, they both sell them.

Great info...Thx for sharing...The finished stone looks great...how long did it take?
Thanks, this one was around 35 to 40 hours.
Son derece güzel bir kesim işçiliği uygulanmış. Elinize sağlık başarılar dilerim. !!!!!
Çok teşekkürler.
That is amazing I love to cut lab made obsidian that is a so good 😊 to see someone else cutting the same style of mineral the saying more to life than a diamond you have prove this that is a ripper well done.
Thanks very much.
Gems by mbk just good to see some else working this style of mineral at the moment cutting a piece of orange 🍊 lab grown obsidian love my greens and oranges and your self.
@@danielvecchi9939 Thanks, daniel, some say the glass stones can be dangerous to cut with the lead or boron additives . They can make some pretty gems.
Gems by mbk l love faceting have you ever tried to polish on a vinyl lap and if not what are yours reasons for this just would love to know. What is best minerals you can easily polish than other minerals.
@@danielvecchi9939 No, i have not tried a vinyl lap, actually i have not seen any available. That would be a lap to be used for soft gems which i have not cut many. Im getting good results with the laps i use now. The easiest i have polished would be sunstone feldspar, topaz, zircon, garnet. the harder ones are peridot, cubic zirconia, sapphire, quartz.
Man I am in such awe of your skill and I only ask this out of curiosity, but what were those little seemingly subsurface scratches on the bottom of the gem when it's rotating on the rotating presentation platform at the end? 23:16 it's pretty apparent, but I'm sure you know what I'm talking about. What is that? Imperfection in the glass?
Thank you. There are imperfections that seemed to be invisible early on then appear as i cut further. They look like hair like inclusions. I did have lots of scratching issues with the cutting and polishing , you might be seeing tiny scratches also.
@@tennpikr74 Super interesting stuff, sir. Thank you for taking the time to teach me!
So I keep thinking as I watch these videos: If one of you guys were to produce and then market a tiny little treasure chest filled with relatively cheap but pretty gem stones, I'd pay quite a lot of money for it. Maybe different sizes, different qualities up to very expensive versions with better gems and maybe tiny little gold coins or something lol.
There are quite a few of us IT nerds with expendable income who would absolutely love the idea of owning our own little actual treasure chest with actual treasures. You could market it to gamers and collectors.
Sorry if it's a dumb idea lol!
And thanks again, sir!
Good art .briliant
Never imagined that an ordinary glass could shine like a real emerald! Outstanding work! I feel decades of experience in every your movement!
I have one maybe dumb question, have you ever tried to use sealing wax instead of epoxy glue? It departs a lot easier, and you can use it multiple times unlike an epoxy glue.
Thanks very much, i use faceting wax almost everytime but this big gem , i wanted no chance of failure so i used the glue. I do agree the wax is much easier to remove .
@@tennpikr74 You've made a quite right decision, epoxy didn't fail you and you've made a beautiful gem! My 11 y.o. daughter literally falled in love with it!
Perfect
What machine do you use? I am wanting to cut a large stone that cannot be smaller than 40mm finished.
I use a facetron machine, The finished stone was 48 mm in diameter.
Hi! How I can get that polish? What kind of disc I need, and polisher? Sorry for my question, I'm rookie in lapidary. Thank you and congratulations!
After you get the facets cut to the 600 grit stage you must prepolish at 3000 or 8000 grit. You can buy precharged laps here: www.shop.lightninglap.com or you can buy copper or zinc laps that you apply diamond paste to. Once you have prepolished the stone i use a lightning lap cerium oxide lap to final polish.
The zinc and copper laps can be purchased here: www.gearloose.com. happy cutting.
Watched this video about 3 times now for reference and it's been a huge help! 2 questions: Did you use a jig to set your dop stick and let the glue harden? Also what kind of dop stick are you using? Thanks in advance!
hello, i did use the jig while the glue was setting up, i used a cone dop as the sphere is round and it would work the best. After i slid the moving part of the jig together to touch the sphere , i have to keep moving the whole thing and turning it so that the glue wont run off or to one side until it set s up, usually about 2 min. or less and it stops flowing. after that i mixed up more glue and built it up around the dop. i didnt want to take any chances for it coming loose.
@@tennpikr74 Okay that makes sense. I have been using my lathe to keep it turning for me, but it's a rather large machine so I would like to find a more practical way of setting the dop stick. Any links to a recommended jig that I could buy? Thanks for the reply!
@@calebanderson3951 I recommend the jig made by poly metric , zane the owner can set it up to work with ultra tec or facetron dops as well as any 1/4 in. dop. I made a video recently comparing a couple jigs .
www.polymetricinc.com
I want it...Lol😳😝😂 Very beautiful piece ❤ ❤ ❤
Thanks very much.
good when there is good equipment
You say that you ran into several problems with this "gem" because it was a 5.5 on the Mose scale.
Is that because the "gem" is to soft or to hard? I know the Mose scale goes from 1-10, with diamond being 10 and ruby/sapphire being 9, and most steels bring in the 5-6 range.
Yes , the softer gems can be troublesome to polish as they scratch easier than hard ones.
ไม่อยากจะเชื่อเลย ครูเก่งมาก
ได้ผ่านจากการ ซึ่งได้เจียรไนแล้ว สุดยอด ของความ สวยงาม มากมาก เลย ครับ ผม
ขอบคุณมาก ๆ.
is it just me or in the segment where you are showing the gem off outdoors you can see some marks on the table that indicate you had contamination in your final polish compound of a much coarser grit?
That is what glass will look like when the sunlight hits it just right. Those marks are invisible everywhere else but direct sunlight. If i had polished further with 100 k or 200k diamond those might not be visible.in the sunlight . Thats my take on it anyway.
I don't give a damn if that is just glass...that is very beautiful!!!
thanks very much.
You are FANTASTIC !
Ha ha , I dont know about that but thanks for watching.
@@tennpikr74 how long do the lapidary wheels last? Do you have to replace them often?
@@jimbuxton2187 if you treat them well, cleaning them after every use , some can last over 10 years.
@@tennpikr74 wow! Thanks for all your beautiful informative videos!
@@jimbuxton2187 Thanks very much for watching.
10:30 when you staryed gliding along the sphere surface the glue seemed to come off really easily
i had heated it , thats why.
Bravo
Legal linda lapidaçao
very good
Great Job .......
I appreciate your hard work and passion but after all this is a piece of glass, not a gem !
Am a wrong ?
It looks soooooo beautiful !
Yes , not a true gemstone. it is virtually worthless. I did this purely for the challenge of cutting a very large piece. Im just used to calling them all gemstones. I had to choose the glass as anything natural or a precious material would be unobtainable in this size or astronomical in price.
I guess i might have been able to find a piece of cz but then it would have cost at least $100 . This piece only cost about $8.00.
Superb. It does look a little doorknob like though.
just a quick tip for dop transferring: when remobing the first dop on such a large specimen you can simply take it to the saw and cut off the top of the dome where the dop is epoxied. Then just heat up the removed head without worrying about heat transfer to the other dop. Probably save 15 minutes.
Right , I actually did that on the the large portuguese cut I did last year . on this one it didn't seem too much excess material to bother with, plus you have to be careful not to scratch the pav. or polished girdle when you take it to the saw. I just did another large Portuguese quartz but this time I did a better preforming job so the crown end wasn't as big. thanks for commenting.
@@tennpikr74 A while after I posted that I had a sudden concern about cross contamination from the saw blade/water. I suppose you'd have to be extra careful about cleaning the specimen before grinding.
Lovely work, by the way. You, and other youtubers like yourself, have inspired me to design a cut of my own. and I can visualize the finished form already. I'll begin researching how to make that table of angles and depths.
@@garrettragsdale4826 hello, i do clean the stone somewhat after sawing but im not extra careful since when i start the grinding im always using a very coarse disc so i never have had contamination on those discs that i know of.
congrats on designing your own gem cut. one of these days i may try also. thanks for your comments. do you use any computer programs for designs?
@@tennpikr74 When I find the right faceting machine I'll make a video about my new design. I'll link it to you. Thank you for inspiring me.
this might be a stupid thing to ask but im designing a watch for my brand and I was wondering if their was a way to to tunnel in a 4mm by 12 gold word inside something like moissanite aha :P
I havent heard of anyone ever doing something like that.
@@tennpikr74 oh well guess ill just mock it up and ask manufactures thanks anyway :)
Spectacular...Amazing! Now do an " Ashoka " cut or an " Octavia Asscher cut " better yet a Bez Ambar Blaze cut :) Wow you are a Pro! Kudos Spectacular cutting skills :) XOXO
Woooow! 🤩🤩🤩
My 1000 grit polish looks like your 240 grit polish. What am I doing wrong?
Your lap must be a newer one . My 260 is well worn but still works ok for this material. Once a lap has worn down it will start leaving a smoother finish.
Show...belo trabalho...
Obrigado.
Luv GEMS
that would make for a very interesting knob on a cane or door handle
Yes, i might make a few soon to be sold as that.
Where are you getting these gemstones I need namita

Hello how are you:
How do I get such a machine.
I have an opal stone, one piece 3/900 kg.
Thank you for your kind cooperation
They are for sale in this country, USA here:
www.facetron.com
What do u call this machine which u stick u r gem?
The machine i used to cut the gemstone is called a facetron faceting machine.
how do I do tell what kinda stone I have
You would need to have a gem cutter examine it.
My wife knows I'm focused when the facetting porn music is in the background. I've learned a lot watching you work. The stones you cut are always glitter bombs.
Thanks very much brandon.
