Hello to all lovers of gems !!! My name is Yuri . I live in the city of Kyiv (Ukraine). By profession I am an engineer - geologist . But in the 90s of the last century, I began to professionally process gems. He started with making cabochons, carving, making balls. Later, I mastered cutting and jewelry making. At the moment, I am mainly engaged in the manufacture of jewelry and cutting. But I've been tumbling a lot of the time. I have made several tumbling machines. But later he sold almost all of them and took up jewelry and cutting. My wife Elena loves to make pictures from gems. By and large, it was for her that I made tumbled gems. I left myself only a vibro-tumbling Grobet (loading about 5-6 kg). And recently I bought a small one, made in Ukraine 20 years ago. It can already be said antiques, but it works. I once had three of these. Its volume is about 0.5 liters. Working cycle -27-30 hours. Very good design, but unfortunately the volume is small. On it you can adjust the speed of rotation of the engine, as well as the amplitude. Since I needed a large number of tumbled gems, I bought a Grobet vibrotumbling machine. Everything in the photo is processed on it. But at some point, the quality of polishing began to deteriorate and I had to buy a second bowl for polishing. Much to my regret, they brought me a smaller bowl. Since the amplitude is not adjustable on this machine, I cut off part of the eccentric (see photo). That is, now you can use bowls of different sizes by screwing additional weight into the eccentric. This will also help with tumbling fragile gems that are sensitive to impact. Perhaps this will be useful to someone. After the sale of a large tumbling machine (the photo shows the first not entirely successful version, the photos of the others have not been preserved), I had about 150 kg of unpolished material left. Over the past few years my wife has used a lot of tumbled stones in her paintings. And the question arose of how to polish the remaining 150 kg of gems. And suddenly I realized that for 20 years I forgot what cycles are in the processing of gems in a vibrotumbling machine with a plastic bowl)))))))))). After that, I found your forum, registered and looked at your advice with pleasure. Thank you very much !!!!! By the way, all the stones that I tumbled, my wife and I collected ourselves in quarries and on dumps of mining enterprises.

Welcome to the forum Yurii! Your rocks look great. Really nice shine on the tumbles. I don't know if I've seen a lapidary mosaic that I've liked...until now. I'm really taken by your wife's art! Your tumbler is pretty amazing looking too.

Hello and welcome yurii! I absolutely love your wall art - like rockbrain said I think this is the first time I have seen rock wall art that I really like. I can't figure out which one I like the best - probably the owl.The background leaves are a brilliant choice.

Super interesting stuff. I particularly like the use of the white stones. I was first drawn to tumbling and lapidary when attracted to the patterns possible with uniform ovals and discs of white shells available in abundance. Ditto, I work with opalized wood that resembles your examples. Welcome and thanks for the photos.

Thank you, dear colleagues!!! I will definitely pass on your words to my wife. She will be very pleased. And this gives an incentive to work further. I didn't quite figure out how to thank everyone who wrote to me, so thanks to everyone. I hope to give advice to beginners in other sections of the forum to help them master the processing of gems in the best possible way. All my experience is obtained by experimentation, so there are some nuances that differ from those generally accepted in the gem processing literature.

Hi and welcome from Northern Arizona! I love your wife's pictures. My favorite is a tie between the praying mantis and the owl. Would love to see pictures of your work, too. It's always interesting to read of another person's process for doing things. Little nuggets of gold knowledge are always hidden in them.

You and your wife's work is beautiful. I especially like the praying mantis. I hope to see more of your work and congratulations on posting pictures! I love that dirtsifter - The university i work at brought together student orgs (we have a Ukrainian student population on campus), staff/faculty volunteers to put together medical field kits to send over to Ukraine - I was proud to have been able to help that effort. I love to see the other ways people have come together to help.
