Gem Cutting Tutorial - Reading a Gem Faceting Diagram - Part 1
HTML-код
- Опубликовано: 16 фев 2020
- Bopie's is starting off the new year with a new two-part lesson for our aspiring gem cutters from award-winning gem cutter Michael! In this video, Mike breaks down all of the different parts of a gem faceting diagram to the last detail, so that even brand new cutters can understand everything that's needed to make a certain gemstone cut happen.
If you are new to the gem cutting hobby or if you aspire someday to provide professional gem cutting services, or if you were simply out hiking recently and stumbled across a pretty colored gemstone and were thinking about all the possible gem cutting shapes you could make with Dremel, then this video may help give you some pointers.
As always, if your travels take you near me or our store, please drop in, we would love to talk to you about this unique trade. If you are interested in learning new gem cutting machine prices or you want to know which cutters currently have used gem cutting and polishing machines for sale, just ask as I am always happy to answer any questions you may have.
If you are thinking about attending a gem cutting school to take more formal gem cutting lessons or even complete Gem Cutting 101 courses, I would recommend you first search for a Gem Cutting Club or Lapidary Club near you as they will have the best information on what is available in your area.
We're always open to hearing from you about ways we can improve our tutorials! Please let us know in the comments how we can help you be on your way to mastering the art of gem cutting.

This is like having Jeff Bridges explain the Lapidary Arts. I love it.
lol. Thanks.
You a perfect example of ecumenism that is the fullest understanding what exactly you are doing, in your this case you definitely know how to explain to a amateur the way he or she should be taught....Thanks for that good effort !!!
Thank you!
I have to agree thank you to all of you. That have put forth a design. I really do enjoy it and I’m glad the world still got people like you all. Thank you.
This is the second time I have watch this video, Tomorrow I will be on my journey of cutting my first stone. I thought to myself I should review Mr. Bopie's faceting diagram and to my understanding the chart much better from the last time, I realized I will be wasting so much of my gem from the design I chose to make because the gem is way to big. Thank you for this very important overview on understanding a faceting Diagram. I enjoy your videos very much please keep them coming. Thank you for all your help.
WOW! Enjoy cutting your first stone. Let me know how it turns out!
Thnks sir the interesting tutorial and the important method how to know about cutting gemstone.
Thank you!

Thank you.
Thank you sir, very easy to understand with the way you explained.
Thank you!
The dude abides 🙏
Thank you,
Great Video. I am going to show this video to a person who has never cut a stone but is interested in learning, this will be a great first step for her. thank you for sharing your knowledge.
Hi five Jess! Scribe to you for sure fam! XD #SmallWorld
Thank you Jess. I am happy to share the little that I know. I hope she takes the leap into the Art of Gem Cutting!
I'm only 7 minutes in and I'm already super happy with this video! Thank you so much for demystifying faceting diagrams for me! I'm very eager to start, will have to wait until March but these resources give me plenty to prepare and entertain myself with in the meantime.
You have to wait until March? Sounds like your new machine is on backorder.
@@mikesackos2208 that's when my course starts, I don't have the money or space to get my own equipment :)
Excellent!
Thank you.
thank you so much for your information and your time.
You are welcome.
Excellent, simple but complete and very useful for all prospective and new cutters. Well presented and great graphics. Looking forward to Part 2 and maybe more of your videos.
Thank you for the feedback Don! I appreciate it.

Thanks, this is a great instructional video that I can use to show people who have never cut what it is I actually do and how.
Thanks Troy! Anything I can do to help advance the art of Gem Cutting makes me happy! There were so many gem cutters who helped me along the way, and still do, so I am happy to do my little part to help others.
This video is invaluable, I really appreciate you making this!
Thank you!
👌👍🌈very impressive video Sir.🙏❣thank you.
Thank you!
Thank you sir
You are welcome
Lol on that volume part though 🤣 vol/w3 😂 had me rolling! Thanks for taking the time to create and upload this video! Got a new subscriber 👍🏾💯😎
Thanks!
Fantastic presentation! Thanks.
Thank you!
Such an informative video. I've saved it. Thanks for educating us
You are welcome.
I love your tutorials . God bless
Thank you.
Thanks for another great video. I was glad to see that I am not the only one that doesn't understand the volume calculation and how it can be used. I have used it to get a rough idea of the "fatness" of similar designs. More volume equals more weight.
Thanks Larry! Maybe someday, one of the very talented cutters in our community will develop a simple app for the volume calculation. I certainly don’t have that ability.
I use the Vol/W^3 measurement to compare yields between different designs of the same shape. IE I can compare a bunch of 1.2 L/W, 1.54 RI Oval designs and see immediately which will yield the most. Granted the color saturation of the stone (thus the depth of the pavilion) is more important than small variances in yield so I tend to look at the Vol/W^3 last.
ah yes, I see. That's a good idea, so if I was cutting an oval for example, the higher the volume ratio, the higher the yield would be. But, for large stones, I am generally cutting a relatively less expensive material, so a little extra yield isn't a significant concern for me. However, if I was cutting a relatively expensive stone, such as Tsavorite, or a larger Sapphire, then I can see where your way would be of great benefit. Thanks.
Thank you so much man. I enjoyed learning from yah and im overwhelmed with joy. Once again thank you.
You are very welcome.
Amazing Video!
I'm a brazilian jewelry enthusiast and i only wait fot the end of the pandemic do start my stone cutting and polishing lessons . This video was the best teaching how to reading diagrams that i have seen. Congrats!
Thank you!!!
Hi very nice info for the beginner
Thank you!
EXCELLENT!!! im about to get started on my first cut gem!! :D this is very helpful
How did it turn out?
thank you so much sir! I appreciate your work very much. I’m super new to the faceting world and I can already tell that your videos are going to be tremendously helpful on my journey ✨✨
You are welcome.
I love the way he pronounces “W”
Well thanks!
Been following your videos for a while now. This is an excellent tutorial on the faceting diagram! Thank you! Also, I got chills when you showed the damaged emerald cut stone at 18:32. I know exactly where that image came from and I can tell you, I had nightmares from watching that video! :-)
Thank you!
very helpful 👌 👏
Glad to hear it! Thanks!
Thank you so much sir
I m from Srilanka
I have gam peices, actually its very helpfull to make my Gems worth
You are welcome.
Thank you!!!
You are welcome.
thankyou..I have purchased my first faceting machine today and hope to pick up this art as a hobbie while im unable to do manual work ..I look forward to next episode..
Thanks for the comment Wayneo. You get my vote for coolest name! Good luck with your new machine, please let us all know how you are progressing. Create a video if you have time, many of us would love to see how you progress, I know I would!! Best of luck!
Any ideas on machine for a beginner? Thanks
@@iPArtChannel there are so many out there and im not sure there are beginner models as such..ive seen and used VJ's at our club and love them but they are above my price limit for home..i have a machine called Agate Master and it does what i need it to..
@@wayne1959 thank you. I will try to find one to start at home. I’m in EU… hopefully I’ll find something 👍🙋🏻♂️🙋🏻♂️
Very good explaining Hobby Cutting.. Now help explain using GEMCAD!
I am no expert on GemCad. I have reached out to Robert Strickland more than once for help! :-)
amazing., i just accidentally found this video series., i was just in there this weekend asking if they knew of any local dealer for faceting machines and if maybe they had an old one they were thinking of replacing., of course they said ., "use the internet., "., well., i don't shop online., but., i would volunteer to work their for free for an internship to their cutter., it has always been a test of mine to walk into expensive stores wearing old work clothes to see the attitude of the front counter., they were at least nice and somewhat helpful even though i was not there to buy stones., just looking for machines., ';'
Let me know when you get your machine!
Thank you for putting so much time and effort into this....and your voice is exactly the same as jeff bridges 🤣
Thank you very much!
Now I picture the Dude every time I watch your videos. The Dude abides. 🤣
Gemcad full license is now completely free.
Yes, that is correct.
Thank you verymuch for the vedio.Is there any software with divice to scan rough gemston and have graphical 3d model of the roughgems.Then we can coinside wirefram diagram on model and select best sutable cut without wasting time and gem materials .
I don't know of any such software, but I don't know much about that type of software.
I'm just getting started in faceting, I've been welding for 20 years and we use blueprints. This looks like it compares to a welding blueprint.
Then you are already several steps ahead in learning to facet. I am not familiar with welding blueprints. Best of luck!
@@mikesackos2208 do I need to get lessons to start or should I get a machine and just start in? Also Im carving opal so I have some experiance with stone.
My friend.
Thanks!
Hi. Can you tell me again how to weight and know the karets. Greetings from Mexico City
Often you will find gemstone rough for sale that is priced per Gram. So you need to know that 5 Carats equals 1 Gram. So if the rough is $5 per Gram, it is $1 per Carat.
Does drawing with 1.72 R.I. work with diamond which has R.I.of 2.4?
I am not sure I understand. If you mean can you use a diagram designed for an R.I of 1.72 to cut a gemstone of a higher R.I., without changes. Probably. In general you can use a diagram to cut a stone in a Higher R.I., but in general, you can not use a diagram for one R.I. to cut a lower R.I. without changing the angles.
If say I have a faceting diagram for cutting a corundum stone but want to cut say quartz to the same design - how would I carry out the conversion of angles to enable me to do it? Thank you in advance. JS.

Not gem cad but it I think it will help you.
Sir, you mentioned only briefly adjusting a design from one refractive index to another in Gemcad. I have looked for a tutorial, but I cannot find one. Please let me know if you have already made one or please make one for us newbies.
Keith, I rarely use Gemcad anymore. It is no longer being supported. In fact, the creator, Robert Strickland, has placed the software in the public domain and you can download it and use it for FREE. I use GCS or Gem Cut Studio. It is simple to change the R.I. in GCS as it's one of the dropdown options.
Muito bom 👍
Thank you.
Does the L / W ratio determine the size of the stone?
In part. The size (carat weight) can be estimated using the volume calculation, which I tried to do in my video of cutting large Mali Garnet. Width Cubed which is width x width x width is one component. You also need the specific gravity of the material and the fraction from the gem design.
Hi Boppie, found your video really informative keep it going with these brilliant videos.
I particularly interested to do emerald cut for emeralds but some how i found some emeralds which have very less depth how ever length into width ratios are good enough, SO can i able to cut those Emeralds with less depth on the same chart which is available on internet or i need to do special depth calculations to implement those charts for cutting or they still work on less depth stones. i hope you get my quetion
If the emerald is cut to shallow, it will have a 'window' effect and light will pass through it and not be reflected back. That affects the brilliance of the stone.
1:47 It's a polish book ;) Are u connected? This book is about tinctures ;) ;) ;)
Yes, you can use that book to polish....to polish off a lot of specialty drinks...lol. It is just a visual aid for the video. I am talking in the video about a how the Gem Faceting Diagram is a 'recipe' for making something...like how to mix drinks. Cheers! :-)
@@mikesackos2208 I've tried to learn how to faceting gems ;) and saw polish accent ;)
Every herkimer is worth to be faceting? Herkimer cost 0,5x0,9 cm is like 5 dollars.
@@olomad6722 I can't answer that for you. Cut what you like to cut. You have to decide if it is worth it. Generally 5x7mm rough is small...but it may cut a nice gemstone. I haven't cut Herkimer...I know everyone calls it Herkimer Diamond...but it's quartz...clear quartz...so is it valuable? I can't say. It is up to you to decide.
I thought it was a gem Faset-ing diagram, not a gem fasting diagram?
lol. Thanks!

Time to learn some useless information :/
