Review on Explore Nature's Gems: NATIONAL GEOGRAPHIC Rock Tumbler Refill Kit with Mookaite, Kabamba, and More - Includes 8 Jasper Varieties, 4 Grit Grades, Jewelry Fastenings, and Learning Guide by Dave White

Very funny box! There is a nice selection of large sized stones including three tiger eyes (my favourite) and some beautiful agates. I am grateful to have received gem quality colored rough stones and not just a box of cheap colorless quartz. We look forward to the final results! Today I fill a glass! Although I already had some sand on hand, I appreciate the included sand set. You can never have too much. Jewelry frames are pretty basic, perfect for kids activities, but for adult projects it's better to buy better frames at a craft store. Glue is not included. You have to buy some. And the gem booklet is very informative. Overall I would say this set is worth the price as after a day of stingy work and house requests, working with these bricks makes me smile. And it's worth it!
