Blue Marble Science Kits NGWORLDREFILL Editorial Review

The National Geographic Rock Tumbler Refill is a comprehensive kit that provides all the materials needed to create beautifully polished rocks and gemstones. The kit includes a 2.27 kilogram mix of rocks and gemstones, such as agate, jasper, and petrified wood, along with 5 jewelry settings and polishing grit. Customers have reported positive experiences with this refill kit. Many have commented on how easy it is to use, with the instructions provided in the booklet being clear and helpful. Some customers have mentioned that their rocks turned out well after following the instructions. However, there have been mixed experiences with tumbling certain types of stones. One customer reported that a small piece of what they thought was quartz became minuscule after 7 days in the tumbler. It seems that the less dense stones may require a shorter time in the tumbler. Additionally, there was a suggestion to sort the stones into hardness groups, especially for larger tumblers, to ensure more efficient tumbling. It's important to note that this kit is a refill and does not include the tumbler itself. Some customers may have mistaken it for a complete set, so it's essential to clarify this before purchasing.
