We recently bought this set of rocks from National Geographic in order to write this review on it, to let our customers know if it is worth buying or not.

Since we already have 90% of the rocks that came in the collection, of course we will sell them on so that they are back in circulation. We like buying from National Geographic because they put funds into STEM learning and games, as well as funding wildlife initiatives in the areas they help.

These two pieces of blue quartz has a lovely polish to it. There are two but the second is quite small so you will get the two pieces for the price of one.
