I'm a sucker for educational gifts and am especially attuned to the sciences. My grandfather was a geophysicist, I embraced all the sciences in school, and eventually got a degree in Biology (which I have subsequently never used). I'm really into sharing learning experiences with my family and have found the Science X line from Ravensburger one of the more reliable brands. I was, therefore, very interested to try out the Crystals and Gemstones Activity kit.
Obviously, this set is geared to a geology lesson. If you're interested in other options, here's a preview of some of the other Ravensburger products:
Exploring Careers
Magnetic Magic
Nature's Energy
CSI Crime Scene Investigation
3-D Optics
Secret Codes
Simulating Nature
Crystal Magic
Electronics And Circuitry
NOTE: These are not TOYS. They are for older children that have a natural curiosity and desire to learn and experiment. Not every kid will have the patience for this set, it provides actual work and learning with review questions and workbook-like activities.
I was particularly satisfied with the 20 activities and various supplies included in the Crystal and Gemstone kit. Many of the projects rely on observation and sensory experimentation. Others give kids the opportunity to create and grow crystals. As with any scientific experiment, results may vary. We had some that worked spectacularly well, and others that were less successful. But listen, having spent years of my life in a laboratory environment, not everything will work out. That's also a pretty important lesson for burgeoning scientists.
I, personally, have always been fascinated with rocks and mineral and this didn't even disappoint the child in me. Some kids will hate it! Some will not think it is fun! But Science X isn't pandering to everyone (although I suppose they'd like the sales). The audience for these sets are a group of older kids (10-14, maybe) that actually enjoy learning to begin with. Is that you're kid? You know them better than me! KGHarris, 10/13.

This set contains a lot of different items, including small rock samples and protective goggles. It's also got some containers and a lot of pouches with different powders in them. I like the rock samples very much - it also comes with some cardboard partitions and directions for making a rock display case.
Unfortunately, I am not sure I agree that the packet contains 20 "amazing" activities. The activities are really slightly less fun (and in some cases a lot less fun) than science class in school. I could see this set being usable in some regards by a homeschooler, but not for kids just wanting to learn on their own. A lot of the activities are really dull and several just don't work. For example:
Activity 1 - look under a magnifying glass. The glass that comes with the set is too small and weak to use for this purpose. Otherwise the "activity" consists of a series of questions about gemstones, like "are there gemstones located in your native country??" or suggestions like "look up the names of countries in an atlas." Then there is a short paragraph about gemstones which isn't really all that interesting or informative.
Activity 2 - scratch surfaces with the gemstones. It didn't work out very well for us - most of the gemstones didn't make scratches in the nice colors shown. Then the paragraph about why they make scratches or colors just isn't that interesting or informative.
The activities go on - do things with the stones that aren't that fun, then answer questions about them and read a short paragraph. It's just not engaging.
As for the fabulous crystals pictured on the box, we have not succeeded with those yet. We've only tried two experiments, but so far all we got was some crust and not any kind of cool crystal. We haven't tried a lot of them, though. Perhaps some others work better. Of course, you need to be comfortable using all those powders and mixing different chemicals together that may be dangerous if you are not careful. Obviously, it's only for older kids, and those who are really interested in science and very patient.
Overall, as a parent I have to say that the kit is just not very interesting unless the experiments actually work. We have not tried them all, so maybe some work better than the two that we tried.
As a teacher, I can see that some effort has been made to follow educational practices in making the activities like lessons, but it's just not very well done. I think the educational value is just not very high - I would not use the activities as a teacher, although I might use the rock samples, box dividers (make your own rock collection activity) and powders.
So I think the kit has some uses, but is really not for a total science beginner or a kid that is not very interested.

This might be the most positive 3 star review you'll read, but as I watched my kids go through this kit, I couldn't help but think that Ravensburger cut quite a few corners here that could have really made this a top-notch kit if they weren't cut. Read on and I will explain.
First,the instructions say "Ages 10 and Up", and you will want to heed that. There isn't much in here that you can tear open and just "do" other than the scratch test on various materials. Most of the kit is growing crystals, which is a process that involves the stove, hot water, and time. So make sure whoever gets this is old enough to enjoy preparing the crystals and then letting them sit. This is not a negative on the kit, but just a fact to keep in mind.
As for the kit itself, the instruction manual is overall pretty good. I have bought some science kits with poorly produced instructions. These are easy to read, colorful, and quite descriptive. All 20 experiments are real experiments, and not just added to fill up space. The kit includes some basic items for doing the experiments, and here is where it gets its first dings from me. When I opened the box, I was greeted with a cloud of Plaster Powder/Gypsum. Yes - some of the kit includes casting things in plaster, and they have a bag of plaster very poorly wrapped inside. The bag wasn't broken, but gypsum had seeped out of the seems. Other disappointing inclusions included a really low-quality magnifying glass, and samples of gemstones that were impossible tiny. Those gemstones came in a small ziplock bag.
The first experiments include classifying the gems, but oddly enough, the instructions include no map - they tell you to "get an atlas" to find where the gems are from. It then has you perform scratch tests to determine where they fit on the Mohs scale. It would have been nice if the scale shown included the gems in the kit. They are so small it can be hard to tell if you actually scratched them successful.
I was also surprised that the experiment where you build crystal structures out of toothpicks included wax but no toothpicks! Would it have killed Ravensburger's profit margin to include toothpicks in the set?
The last experiments are where it gets interesting. You get 5 different chemicals including Alum, Chromic Alum, Ammonium Di-Hydrogen Phosphate, Seignette Salt, and Potassium Hexacyanide Ferrate that make all sorts of cool crystals. You grow these in jars (you must provide) and see how each chemical forms different crystals. You can then grow crystals on a stone, grow them on a plaster diamond, grow them inside a plaster geode, etc. The crystals are beautiful and my kids enjoyed seeing them grow.
So conclusion? It's an nice set of chemicals for crystal making, so I can recommend it if you want to take your crystal growing beyond sugar and salt. Anybody can make sugar or salt crystals in their kitchen, but some of these chemicals may be hard to get on your own. The kit is well worth it for this piece. However, don't buy the kit expecting it to come with decent samples of gems or complete tools for doing the experiments. Even something as simple as a toothpick you will be providing. As long as you understand what you are getting, this could be a worthy buy, but it has enough "gotchas" that I need to rate it 3 stars.
