You will receive a little box that measures about 5.5cm x 4.4cm similar to the ones in the photos with a mixture of small (about 0.5cm) tumbled gemstones.
Each box is different and will have some or all of the following types of crystal in them in them; Quartz, rose quartz, turquoise howlite, amethyst, turquoise, carnelian, agate, jasper, tigers eye, new jade, fluorite, aventurine, unakite, howlite...and maybe some more that I've missed : )
These boxes are really sweet but not recommended for very young kids as the stones could easily be swallowed.
