Blue Marble NATIONAL GEOGRAPHIC Break Open 15 Premium Geodes - with Goggles, Detailed Learning Guide, 3 Display Stands, Great Stem Science Toy & Educational Kit

Bought this for my grandson and hubby to do as a project over the weekend. Not sure if I missed something in the write-up but I didn't realise that you need a chisel, luckily we have several at home. Some of the crystals are vastly more difficult than others and you can see from the pics that we had to upgrade the chisel to a brick bolster (big daddy chisel) to get some of them to open. It may have worked using the original chisel but after half an hour on one rock the replacement was recruited. Luckily most of the stones are easier to crack open and averaged 5 to 10 minutes with my 11-year-old grandson managing to do some on his own. He loved using the tools and this is a good way to start teaching them about handling tools. He was really excited with each one they opened and loved looking for the exact name of each in my crystal books. It was a shame that a lot of them were so similar - clear quartz, smokey quartz and pyrite being the bulk of them. There was no brightly coloured geode but still very nice. A couple were left whole simply because they looked so nice as they are. One is a naturally egg-shaped pyrite which looks like the golden egg of fairy tales. Its a pity that there aren't more display stands in the box and to be honest I am replacing those provided as they didn't seem suitable for any of the opened geodes (one was a nodule which is filled with crystal - one lesson we learned!) Overall I would definitely recommend this as a way of entertaining older children both whilst actually using and the interest it generates. You do need to use quite a bit of force so choose a dry day and work outside as you do get chips flying off - they do provide one set of goggles. Packaging was sturdy and protective without the extra packaging that you get with some products. please note that I received this item at a discount in order that I would provide my totally unbiased review.

Great gift

Bought for my daughter. She loves it. Not opened all of them but it feels the chance of finding any with any colour are slim. But still fun going mining in the garden Update: Not all of them are geodes so really disappointing and not worth the cost of a child being upset

Awesome geodes. Look amazing when cut, I would say don't smash them. Look way better cut or opened with a hammer and chisel. If you sand the outside a little makes it easier to break open into two halfs. Awesome value for money. Really enjoyed opening them. Some were thunder eggs more than Geodes, solid inside which I loved but some may not enjoy if they want it hollow with crystals. I think thunder eggs are way more beautiful when sanded so all good. Only 4 out of the 15. I got a good variety but not a fan of quartz geodes as I have lots. But the ones in the pack had larger clearly crystals which I loved. I break them up and make jewellery and keyrings off of them so amazing for me I sanded down one that broke into bits and it's turned purple. Which is awesome. Defo recommend If you like minerals, gems and rocks. 😁

I was really looking forward to seeing what types of crystals i would get out of these but i was really disappointed when 3 rocks didn't have any crystals in and were just solid rock (i kept cracking them to see if there was a vain or anything but nothing). Also, we only got 2 type of crystals (clear quarts and calcite). Don't get me wrong they are all stunning in their own way but I was hoping for at least one other type so that everything wasn't just clear. Some of the stones were really hard to break so I wouldn't recommend kids to d this on their own.

Be prepared to use your muscles. We purchased a large chisel with hand guard and used a small but weighty metal mallet. We positioned the rock in a towel nest on concrete in the garden, away from windows, and whacked away. These were purchased for a 8 year old who had great fun fitting them but just couldn't break some. All very exciting and all round a great gift. Everyone joined in and there were lots of oooooos and aaaaaahs.

This was quite a disappointing experience to be honest because I was not expecting world class geodes but when the box says 15 premium geodes you expect something more than a rock in your kit.I highly recommend that you don’t buy this product for your kids because there is no variation in the geodes crystal colour and you end up with 10 segments of quartz geodes and about 20 rocks. Do you want your kids to be sad? Save money Save disappointment Save regret And buy something else

Trying to find alternatives to video games? Think your kids will benefit from hitting things with a hammer? Then this gives you an afternoons worth of focus! Because there are 15 geodes and some are pretty tough, it gave the kids an activity for a good couple of hours. Each geode produces at least 3 sections, the larger ones many more. Some are a bit duff some are really beautiful. That’s part of the fun. Quite expensive, but good fun and a nice ornamental display

My 11 year old son really enjoyed this Geode Kit even more than he expected! He is at the age where he is hard to shop for aside from video games and electronics, I wanted something fun for him and I to do together as well as a learning tool. He has shown interest in rocks, gems, and crystals so I thought this would be right up his alley and boy was I right. Since cracking open the very first geode his curiosity and excitement began to intensify and I loved helping him out. This kit really provided a nice assortment from solid to hollow and a fair variety of size and colors also. One of the geodes was actually filled with a bright sand colored dirt which both of us thought was really cool, he immediately said "I wonder how old this dirt is" which let me know he was getting a hands on learning experience. We will definitely be interested in purchasing more sets just like this one and I won't be so lost come his birthday as to what to get for him or recommend to others. The set does come with safety goggles which he put on and used without my having to ask as well a small information booklet on the different geodes. I definitely recommend purchasing a chisel and rock hammer to get better splits on the rocks but we made do with a flat head screw driver and house hammer. Some of the solid heavy geodes were a bit hard to break and we even ended up using a sledgehammer on it! Another tip I recommend is to break them on a hard surface and place the geode inside a zip lock prior to cracking to keep all the bits contained. Overall I am extremely pleased with this purchase and it has definitely become one of our new found hobbies thanks to this kit.

Exitoso regalo de navidad

Good

Comprato per un regalo a mio figlio. Bello rompere col martello o col seghetto ed è una gioia immensa scoprire i cristalli all'interno, ogni pietra ha cristalli di diversi colori e forme. Una scoperta continua è come una ricerca del tesoro. Il prezzo ne vale veramente la pena. P.S. con un po' di voglia si possono fare anche dei piccoli gioielli.

Son súperbonitas. Aunque no tan fácil de abrir siempre. Añadiría más soportes no solo 3, que vienen en el paquete. Me gustaría también saber que estos exactamente de donde proceden y cual es su sítio de origen. Quiénes los encuentran. Así sería más interesante y entera la experiencia.
