## Questions & Answers

**Q: Do the geodes contain different crystals or are they all the same?**
A: Ours were all white - disappointing given the pictures in the advertisement!

**Q: I bought this and I’ve just cracked them all open and they’re all just basic quartz, is that what is supposed to happen?**
A: Primarily white crystals will be found since many different minerals produce a white crystal (e.g. quartz, fluorite, calcite can all be white). Unfortunately, we do not have a way to ensure color geodes are found since part of the fun of geodes is not knowing what is inside until you crack them open!

**Q: If there are 10 geodes, why are there only 2 stands? What am I supposed to do with the other 8?**
A: I bought a cheap plastic box from Hobby craft.  It is divided into 12 ..for sewing stuff I think. We put it on its end and put an opened geode in each. It makes a perfect display case.

**Q: Find hammer for geodes**
A: I bought a small soft grip stanley hammer and a set of chisels for this set as a hammer alone is not enough. My 9 yr old could use them himself under supervision but some of them are fairly solid and  hard to crack so needed adult help.

### ⭐⭐⭐⭐⭐ Brilliant. Must buy!
*by S***W on 27 December 2025*

Absolutely brilliant. Realy impressive and genuine geodes. My son is seriously impressed with this and hes been left with some really good crystals for display.

### ⭐⭐⭐⭐ Grey/Blue Geode
*by A***A on 21 January 2026*

Very impressed so far! Obviously my so. Wanted to open the largest one and also a darker colour than the rest. I had read the previous reviews where people were disappointed, so I made sure he knew there was a possibility they might be all white. I think they are beautiful whatever colour and the rest are going in his party bags as party favours. 4stars instead of 5 for the size variations some are tiny.
