National Geographic 4-Stage Rock Tumbler Polishing Media Kit
This comprehensive kit provides the necessary abrasive media for polishing stones and gems through a multi-stage tumbling process.
The National Geographic Rock Tumbler Media kit is designed for hobbyists looking to transform raw stones into polished gemstones. It features a 4-stage bulk grit system, providing the specific abrasives needed to move from rough shaping to a smooth finish. The kit includes approximately 1.5 pounds of ceramic pellets and GemFoam polishing media, which are standard materials used in rock tumbling machines. This setup is intended for users aged 8 and up who want to engage in geology-based crafts or jewelry making. When evaluating this purchase, buyers should compare the total weight of the grit provided against their specific stone types, as harder stones may require more material over longer cycles. It serves as a bulk supply kit meant to replenish tumbling media rather than providing the actual tumbling machine itself.
