Product Description

Geodes are formed naturally by volcanic activity. Bubbles in lava harden, over time natural crystals grow inside of the lave bubbles. Have a great time breaking these geodes open! There are 12 geodes in this pack ranging is size from large marble to golf ball size. They are 90% hollow as with all the geodes sold by Gem Center USA. Geode cracking instructions are included; once the geodes are opened use the geode identification guide to determine which minerals you discovered. Amethyst (rare but possible), smoky quartz and clear quartz natural crystals are found inside these geodes! It's a surprise every time you open one! An Ancient Treasure is waiting to be discovered!!! Great family fun and educational for the kids! 100% naturally occurring geodes with real, genuine crystals! "High Quality Geodes": These geodes have been carefully sorted to insure that they are almost all hollow. The crystals inside will be consistently clean and sparkly with a variety of colors!

After reading poor reviews for many of the geodes available on amazon (small, lots of duds) we paid a little more for these geodes. We were not disappointed. I used them in a geology summer camp and every child had a good geode. There were no "duds" in the packs. Gem Center USA delivered a quality product at a good price. I will for sure buy from them again next summer. They are not extremely large but the kids were satisfied by the size. The kids thought the geodes were very cool. We had the greatest success cracking them open with a hammer and cold chisel. The geodes contained a mix of calcite and quartzite crystals in various colors. The crystals looked great under a dissecting microscope. These are a great teaching tool or just as a fun gift for a person of any age interested in the subject.

I shopped around, looked at reviews. Ended up w/3 of these sets from Gem Center USA (with that name, how can you go wrong?). The one we kept is shown in the video. 12 geodes, ranging in size and color. Obviously rocks were picked from various regions and combined into this great gift. Well done. My 8 year old was so thrilled. And I was, too.

We bought this as one of the Christmas presents for our child this year. See the picture I provided with the product listing. What you see is a tray of a dozen, carefully broken geodes by a 10 year old (of course, under adult supervision). The package of 12 geodes came with instructions, again, see the picture I uploaded. We used a sock and a hammer, carefully following instructions. Both parents and child had fun with the process and were very pleased to see how pretty these geodes are inside! There were no duds. An important pointer: since these are small geodes, try not to hit them too hard or they will get pulverized and you will end up not seeing the real thing and you might think you got a dud. Highly recommended for educational purposes and fun! I would also recommend accompanying it with a geode book for the recipient to read.

I got this as a Christmas gift for my 13 year old son. He loved it along with my 12 year old son my 7 year old son and my 14 year old nephew. They immediately took these geodes, a sock and hammer to the garage and cracked them open. It took 2-3 tries to get it to crack open and he was so excited and proud of himself when it cracked into two perfect halves. I will definitely recommend this product to anyone with children interested in science. It's awesome.Thank you so much.

I dragged out my great uncles machinist vise (about 50 pounds) and gathered up the safety glasses, large hammer, gloves and a painter drop cloth along with a pad for kneeling. My ten year old grandson looked every part, the mad scientist as he cracked the geodes to discover the crystal formations within. I told him that he was the first person to ever see the inside of each stone. He rated his gift as the second best present that he had ever received for a birthday. The pieces and sparks flew in spite of our attempt to capture all the parts. Some geodes were very nice crystals while others were nearly solid but all were interesting. Some of the solid chunks are going to be finished in a rock polisher while the nicer crystals are decorating a bowl on an end table. It was definitly a new experience for my grandson that he won't soon forget.

From the picture on Amazon it look like you get a big bag of large rocks. Well not the one i received. I bought this set of geodes based on reviews and with a higher price then the others i figured it would be the best. I received a small bag inside of a little box. And the rocks were much smaller then i had imagined and one was only half of a rock. l was shocked and disappointed. Had i known the size i would have never spent this much money, 25 bucks. Not the wow factor i thought they were going to be on christmas morning for my kids. There are 12, well actually 11 and 1/2 about 1" big. My kids have bigger marbles then these things. Oh, and they are very powdery. I would not buy these again unless they were $5, than it may be worth it.

These geodes are very small and quite a few of them were extremely hard to open for my 10 year old. Some we couldn't even hammer open. The variety of colors inside of these were good. Overall fun little project, just a little pricey for what you get.

Gave this as a birthday present to a rock-loving kid. Got an excited thank you within days. Before I bought one set, I told my son what his friend would be getting, and he wanted a set too. We'll do ours this week, and he's excited. Considering that few things these days get ten-year olds excited, that's already a big plus.
