Very educational. Thank you
Excellent information. Thank you for the upload.
That was amazing. thanks for the upload
my pleasure
Amazing art. I wonder who pays for this nowadays, when cutting a stone with machines is so much faster, cheaper and better. They must have a great supportive customer base.
The owners of the finest quality material who live in European cutting centers such as London, Paris, and Idar Oberstein don't risk giving their 6 and 7 figure stones to cutters in the East. There is still enough expensive material to keep these guys going for now and long into the future I hope.
Very nice.
Nice method. Here I use a grit to remove impurities, then In clean it using liquid soap. And also I scratch using a blade. And finally I put the abrassive and using a hard quartz or an agathe to clean
Im new to the world of faceting, with a background mecanical machinery.....this brick method has me worried for the plane of his lap ! Im sure it works since its clearly not his first rodeo, but i wonder if hed try to facet a large stone with over 20mm side the end result !?
They frequently do large stones! no problem. I started using this technique on my batt lap and copper laps and it works well but its a lot of work for your arms so I've gone back to the razor blade.
My method is almost same, I use sand paper. I also use agate, best in my openion. Never used the ball bearing thing.
:)
I don't like the ball bearing thing it tends to walk all over the lap hard to use.
Thank you for the beautiful video, can you please let me know what kind lab is copper and thank you so much for info
The copper lap is for cutting. 400 grit diamond on it.
@@JustinKPrim Thank you so much. How you polish ing the diamond what kind lap? If you can . I really appreciate it you answer me back thanks so much and happy Easter.!
@@janhachicho3373 Are you asking about polishing a diamond or using diamond powder to polish colored stones? Diamonds are usually polished on steel or iron laps with diamond powder.
@@JustinKPrim polishing diamond what kind lap and what kind powder, I am new with gemstone I love it to Learn more about cutting stone please I real appreciate it your time.!!
@@janhachicho3373 I’m really not sure. I only cut colored stones and not exactly sure of the technique for diamond polishing
My god, cutting on these laps with jam peg technique......I feel like I time warped back to the 1850s.
Peut être quelques sous titres français pour dire ce que sont ces grosses "eponges" dures qui rayent le cuivre?
Les "éponges" sont des blocs de grès utilisés pour rendre rugueuse la surface du cuivre et la rendre parfaite pour contenir la poudre de diamant.
I never dress my copper laps clean them and apply more diamond as needed with a hard stone. I only scrape with a razor blade if it is scratching.
I can’t believe these old machines still works in modern days
It's amazing right? I've been getting more and more obsessed with this old technique. I am planning on buying an old machine the next time I get to Europe and I am going back to do more training at this studio in June if things settle down. I love the old technique!
@@JustinKPrim can you share where you would buy one from please?
@@AS-qk9xn The website that sold them is gone now.
I DONT USE ANY OF THESE THINGS USING FINGER TO APLY DIAMOND HOW HE KEEP FROM CONTAMATION AN D USING THE SAME LAP ?????????
No need to shout. You're not the only gemcutter with a technique. This method is hundreds of years old and is at risk of being lost. Only about 9 cutters still exist in Britain who have apprenticed and learned this technique.
Here I am with everything in a labeled plastic bag to avoid contamination, cleaning and whashing my hands non stop.
how does it even work? how does he not cross contaminate everything ? xD
Cross contamination is a myth 😈
👍👍👍👍👍🇧🇷
I am very new to all of this but I can say with confidence that I will NOT be using this method to treat my copper lap !
:) Not for the faint of heart I guess
