I really appreciate this video Justin, I just started cutting stones at my local lapidary club and this video helped me figure out where I was going wrong. I was assuming my angle-stop would perfectly balance my facets but I see now this is where personal skill comes in vs mechanical aid. Thanks again.
This is excellent. This sample is much appreciated. I learned how to cut completely on the internet from the G.O. forums and the USFG email list from people who were gracious enough to share their knowledge such as yourself. I really can't express how much I appreciate your work. Have a lot going on right now health wise but I hope to be back to cutting again in 2022. In the meantime it really brightens some dark days when I see you have posted content, thank you.
In the early stages of balancing a crown i feel like a pair of calipers would exponentially speed the process up. After ten years of custom fabricating to tolerances of +/- .05⁰ the appreciation for your eyeball calipers is immense, not many people think about the skill involved behind the stone, let alone the time it takes to get there. I greatly appreciate this video, all of the information i was looking for in one spot to set me on my path of cutting!
Excellent presentation and filming. Cutting the table first, and not using a transfer jig were alarming, but one cannot argue with the result. Extremely efficient work, on an accurate machine, an absolute pleasure to watch. Thanks for sharing this, it’s quite inspiring!
I love the quality of your video with the HD and yet with the PIP at the corner of the screen while you are talking and working at the same time as good as for the interaction. LOL! You have quiet lot of knowledge and very skillful.
Thank you. It took about a month to get it all set up with lighting and setup and all the furniture and props and getting all the cameras working together. But after it was all finished, I think it looked great. Thanks for noticing.
Man I can’t believe you did the transfer without a jig that scares the fuck out of me hahaha good work man! And also it’s just interesting/funny how every artist has their own way of doing. Like how you use the double polish laps, I would NEVER but for you they work amazing! I’m a Batt lap kinda guy and Batt5! Straight up the best/most accurate/fastest polishing disks I’ve ever used.
beautiful job and awesome video,ive watched all the videos about cutting gems and this video is the best one,im a cabashun cutter but now ive started to cut faceted gems and im using a method from one of your videos about old british gem cutting ways because i cant buy a mechine like yours,thank you so much.🌹🌹🌹🌹
I’m a machinist as well and building my own machine. I can’t stand vibration and anything out of balance or slop in the movement. But yeah that chatter when polishing was like nails on a chalkboard to any machinist.
very useful learning for beginners, I hope this knowledge can be useful, I am very motivated to start this new job immediately but my equipment is not as complete as in the video, I will try to find information
why when you cut facets by rotating the gem, facets somehow end up slightly different sized and why do you need to balance them? for a layman it's not obvious why they don't end up perfectly equal.
If we always cut the table on 96, then we will never forget which number we cut it on. However you can make it whatever number you like, just make sure that you always polish on the same index number you cut on. 96 just helps you remember.
@@JustinKPrim Thanks for the response. I'm sure I'm still missing something. Why is it important to polish the table on the same index you cut? Isn't zero still zero no matter which way you index it?
@@williambarnes5023 No. If you polish on different number you will see the the table doesn't come in flat. On the mast machine, we don't get to see this problem because usually the table adapter is keyed to 96 so there isn't another choice.
I am considering taking some classes so Im curious and honestly a bit confused. It would seem to me that the cuts would be precise given the device's purpose. Is it because of this particular lap machine you're using that the depths aren't automatically exact? Are there more precise machines? Or does this stem from the dopping? I wouldn't think pressure would be a factor bc you're setting the height of the glass plate. So I would think it's the machine as I have seen several makes/models. Edit, other than this question you're doing a great job in teaching me so I thank you very much 😊
Great video ?? If you initially cut the first 4 facets at same angle & depth why the difference causing you have to balance 1 or 2? Is it the manipulator?
@@JustinKPrim Does this also happen with the mast machine? Is this why sound signals (ultra tec) or comparators (facetron) are often used in mast machines? Or is this inevitable?
@@nicolapiubel it’s inevitable. You almost always have to manually balance the facets on any machine. An advanced cutter can usually get very close through timing, sounds, feeling but the visual inspection will always be the final determining factor and there’s usually small tweaks to be made at that point.
This is a great idea for a video but in short, I like to take a marker and put it in the middle of the lap and turn the machine on for a second. This gives you a perfect circle. On the outside band apply 8k diamond slurry. On the inner band, Apply 60k slurry. Polish a stone. Dont crosscontaminate.
Hey Justin. I’m really thinking about getting into the hobby. I’m working in manufacturing and I’ve been a draftsman for 8 years. I think I can understand a good part of the geometry and process. Just a quick question: Since I want this to fit with another of my hobbies, how hard is it to craft a icosahedron? This would be my main goal on the long run.
It’s not hard but first you need to understand how the machine works and then understand how to get a good polish. Those two things can take months but go ahead and give it a try and see if you enjoy the challenge.
I’m having trouble sourcing a dop holder/handle that you use for handling the dop during the dopping and transfer process. Closest I’m coming to is a pin vise but cannot find chucks that fit 1/4”. Do you have any source recommendations? Thanks for sharing all of this knowledge.
The Handpiece goes in your right hand and your left hand controls the riser knob. It doesn’t matter if you’re left or right handed, it works the same. You can really put the Handpiece in your left hand because you couldn’t squeeze the index trigger and I think it would be uncomfortable.
I have a lot of stones and I have an account on RUclips under the name of Samon sabra...I have also checked it in the lab but the results are not clear, regarding the type of stone, the hardness of the stone, the elements contained in it, the name of the stone, and the price of the stone bar.. can you help me sir???
I'm surprised that preforming is so much of a hand-held process. Why would you not dop the stone and maintain the control that a facet assembly would give you?
Can link me to a cut sheet pdf for cutting a simple 8-fold mirror for cubic zirconia? I such a novice that I can't even figure out how to Google the proper words to find the appropriate cut sheet!
@@JustinKPrim For CZ (with its higher R.I.) I'm guessing the pavilion P1 angle should be 45 instead of 42 degrees, but I've no idea what the crown C1 angle should be, although I assume 35 degrees would be OK?
hi I'm very happy with your video, I'm from Papua Indonesia, although I don't understand English, but I can understand what you mean, I want to ask if I can get your address so I can send my gemstones and you cut it at your place ? my type of gemstone is on my RUclips.thanks
I think those are the exact same words. :) I have a class on the website all about natural emeralds if you're interested : www.facetingapprentice.com/courses/emeralds-and-the-emerald-cut
The design is to make an easy cutting experience, not for the look of the stone. This design is normally used in tiny melee stones where you can’t see the pattern because it’s so small.
I don’t know what you mean by that statement. Hydrothermal growth (solution process) requires heat and pressure and imitates the conditions deep in the earth that result in the formation of natural gems. Nutrients are dissolved in a water solution, and then synthetic crystals form as the solution cools. It’s one of the ways that synthetic stones are made. I’ve never heard anyone refer to a natural emerald as a hydrothermal emerald. Those are just “emeralds.” Have you?
@@JustinKPrim If you base your knowledge on what you "hear people say", that leads to the error of ignorant people. I repeat, natural emeralds can also be hydrothermal, therefore the correct thing would be to say synthetic, or if you want to clarify the synthesis method it would be hydrothermal synthetic.

coming from being a machinist... the vibration you are getting during polishing would drive me nuts.

So I'm guessing the feet are a rubber like material allowing for a bit of give or pressure. 47:53
No it's a hard plastic. No give, we want firm contact with the glass. If we need to push in more we can lower the plate a bit.
Great video, learned a lot!
awesome tutorial man
Great job Brother 👍

Cool video. My Faceting machine will be here Thursday maybe try that cut first. Do you keep the girdle round and polish them?
Yes, keep the girdle smooth, polish it smooth . Good luck with your new machine.
That’s because 42 is the answer to life, universe and everything.
Looks like the perfect hobby for me, thus that machine takes more energy bills than my airco?
I don’t think so. Aircon takes a lot. This is just a small motor.
why when you cut facets by rotating the gem, facets somehow end up slightly different sized and why do you need to balance them? for a layman it's not obvious why they don't end up perfectly equal.
The cutter has to manually make them all the same size by looking a lot and adjusting each facet to be perfect.
Excellent 👍
Everything is so precise, and then... that transfer☠ just eyeballed😅
No rules life 🤣😂
Thanks
Hi, do the synthetic sapphires still come with the tool kit 2.0?
@@dannygartlan1195 yes but I don’t think the tool kit will be restocked anytime soon. I’m having trouble having them made now that we moved to France.
What's the reasoning behind cutting the table at index 96? If the angle is zero, then shouldn't it not matter what the index is?
If we always cut the table on 96, then we will never forget which number we cut it on. However you can make it whatever number you like, just make sure that you always polish on the same index number you cut on. 96 just helps you remember.

De nada
What device did you use to cut this stone? thank you for the information.
A Sterling ST-08 faceting machine from www.sterlinggemland.com
nice sir Thnks the information.
I am considering taking some classes so Im curious and honestly a bit confused. It would seem to me that the cuts would be precise given the device's purpose.

Thanks 👍👏👏👏👏👏
Thanks sir Im From srilank
it didnt look like you were using any water on the polish...how come?
If you use oil and diamond powder slurry, you don’t need water. The oil is the lubricant and the coolant.
How do you prep a new tin lap to be dual band lap?
This is a great idea for a video but in short, I like to take a marker and put it in the middle of the lap and turn the machine on for a second. This gives you a perfect circle. On the outside band apply 8k diamond slurry. On the inner band, Apply 60k slurry. Polish a stone. Dont crosscontaminate.
I don't have much knowledge about gem cutting. But i want to know doing pavilion side first is advantages or disadvantages. Thank you.
Both sides have their own advantages. This question is too long to answer here but is a good idea for a video topic.

The one that I have is from Sterling. Maybe you can email them and order just that handle. www.sterlinggemland.com
❤️❤️
Could You have used a transfer jig, to change the gem from one dop to the other?
I could have.
So I take it your left handed? Am thinking about ordering the sterling machine I believe its listed as right keft hand .
The Handpiece goes in your right hand and your left hand controls the riser knob. It doesn’t matter if you’re left or right handed, it works the same. You can really put the Handpiece in your left hand because you couldn’t squeeze the index trigger and I think it would be uncomfortable.
Nice video. Why not using a transfer jig?
It’s faster and easier not to. Plus then you don’t need to buy a transfer jig.

So many issues of criticality pop up far more often on these machines as compared to a decent mast type
