About Lortone
For over 50 years, serious lapidaries have considered Lortone the standard for performance and durability. Located in Washington state, Lortone has a long history of producing high value, economical lapidary and jewelry equipment.
Although there is no magic involved in rock tumbling, it does require time, close attention to detail, cleanliness and a certain amount of craftsmanship. But isn't that what any hobby is all about? And a benefit of rock tumbling as a hobby is that you can rarely completely ruin a good stone. You may lose some time through error, and your stone may end up smaller than you hoped, but it will still be a gem. By using a Lortone rock polisher that is built to last, you'll be happy with your rock tumbler supplies for many years!
