Didn't Realy Work. Disappointing results
Very disappointing, used stones bought from national geographic and the supplied extra powders, followed the instructions and after over a month smooth but dull stones. Double checked for small pieces that might be causing damage cleaned everything and did the whole process from start to finish again, another month plus later, still dull. Checked on line said it might be hard water, got some demineralised water and just ran the polishing process, it has taken 6 weeks of constant polishing to achieve a slight sheen on some of the stones whilst a small number are still dull. Very disappointing. Been packed in the loft likely to never come out again, money wasted should have just bought some polished stones.

Not many of these stones can be polished
The rocks are very very rough to start with and.many disintegrate to gravel during stage 1. Others have such deep striations that it would takes years to get them to a state when they could be polished. Quite a disappointment for a Nat. Geographic product.

Fantastic value for money
Such a lovely set. Bought my daughter these to go along with her new Nat Geo Pro rock tumbler. It's great value for money. Plenty of different rocks and petrified wood that will keep her tumbling for a long time. Great variety too. Highly recommended
