Great product!
Update 12/26: Christmas has come and gone, and this set has got PLENTY of play! It was a huge hit for my son, who is extremely picky about his toys. He has sat and played with this for hours, usually 30 to 45 minutes at a time. He loves using the tools, and prefers to identify the shapes rather than colors right now, but he still keeps them matched up correctly. I highly recommend this awesome and incredibly fun toy. You and your child both will have a blast playing with this set! I bought this set as a Christmas gift so it has not yet been played with, but I already know my (almost) 4 year old is going to have a blast with it! There are so many ways we'll be able to play with this, while educating him. Since he is not going to preschool, at-home education is very important to us, and fun props are always welcome! Every piece in this set is large and chunky, making it easy for hands of all sizes to manipulate the pieces, however, using the pick to open the geodes helps with fine motor skills. Each gem's color matches the inside of a geode so it's great for color matching. Could work as a memory/matching game, and could work for teaching about actual geodes, too! So much potential for learning, in such a fun way! Everything seems to be made extremely well, the colors are perfect and vibrant, and the little bag for storage is very much appreciated! Of all the Christmas presents we've bought this year, this one has got to be my favorite.

Good for many ages and both genders
I'm a homeschooler constantly trying to find ways for my 3 year old to be entertained while adding educational value. This was perfect for her (and would be appealing to either gender). Keeps her entertained forever, she loves playing with the jewels, uses shapes, colors, and hand eye coordination. The "rocks" easily snap together by you or your child and hold the gems, they wedge the screwdriver in the hole and bop it with the hammer. The rock "cracks" open to reveal the gem. Well done! I love this brand. Even my 8 year old boy played along.

Fun, Educational, and Perfect for Early STEM Skills
The Learning Resources Rock 'n Gem Surprise Activity Set is a fantastic learning tool for young children. It’s engaging, colorful, and provides a hands-on way for kids to develop sorting, matching, and counting skills. My 2.5-year-old daughter loves it, and I can see how it helps her build important cognitive abilities while having fun. Pros: Bright and Engaging Design: The vibrant colors and shiny "gem" pieces immediately capture a child’s attention. The different shapes and sizes of the gems make sorting and matching activities exciting and visually stimulating. Educational and Developmental: This set is great for teaching early math skills like counting, sorting, and comparing. It also introduces patterns and sequencing in a fun and interactive way. Durable and Safe Materials: The pieces are made from sturdy, high-quality plastic that feels durable and safe for little hands. There are no sharp edges, and the gems are large enough to prevent choking hazards. Versatile Learning Opportunities: In addition to sorting and counting, we’ve used this set for imaginative play. My daughter loves pretending she’s a treasure hunter or jeweler, which adds an extra layer of creative fun. Compact and Easy to Store: With just 19 pieces, the set is easy to store and doesn’t take up much space. It’s also lightweight, making it perfect for travel or playdates. Cons: Limited Number of Pieces: While the 19 pieces are sufficient for basic activities, adding a few more gems or additional shapes would increase the variety and extend playtime. Slightly Simple for Older Kids: For children closer to the upper age range (5+), the activities might feel too basic. However, you can introduce more advanced concepts like simple addition or subtraction to keep it challenging. This activity set has quickly become a favorite in our home. My daughter enjoys sorting the gems by color and shape, and I’ve noticed her improving her counting skills. We also play matching games, which keep her entertained and focused. It’s a great toy for independent play as well as parent-child interaction.

One of the best learning resources toys!
The Learning Resources Rock 'n Gem Surprise set is a gem in our home learning, captivating my daughter with its blend of colorful gems and educational activities. The “rocks” are the perfect size for her little hands to grasp, and she loves “mining” to get the gems out. Considering how much she has been using this toy, it’s pretty impressive it’s held up so well. She loves sorting her “gems” when she is done by color or shape. It perfectly merges her fascination with nature and early STEM learning. The excitement of uncovering hidden gems within the “rocks” adds an element of surprise that keeps her eagerly engaged. As she manipulates the pieces, her fine motor skills and sensory abilities are honed, and watching her learn and grow with every play session is truly rewarding. This 19-piece set not only brightens her day but also lays a solid foundation for critical early STEM skills in a fun and interactive way allowing her to learn as she plays! Highly recommend!

Lots of learning
I purchased this for my 3-year-old, and while he does enjoy it, my 5-year-old definitely gets even more out of it. The concept is fun and engaging, but my 3-year-old has some difficulty opening and closing the rocks independently. That said, it’s a wonderful learning tool for practicing colors and shapes. It also encourages gross motor development, which I really appreciate as a parent. Overall, I would recommend this more for ages 4 and up, especially if you’re looking for something both educational and interactive.

One of the best toys for young toddlers
I got this toy for my 18 month old toddler so that she can get develop fine motor skills while being familiarized with various shapes. It is now exactly 3 months later (21 month old) and she has legitimately played with this toy every single day. It is one of the most useful toys by far. At 18 months old, she was only able to use the chisel (pushing it down) to open the rocks. Now at 21 months old, she’s able to utilize the hammer and chisel (requiring more eye hand coordination and hand control). Not only that, she developed a love for “heart” shapes and is obsessed with the purple and yellow hearts. She learned to express her surprise emotion and silliness opening each rock. The quality of this toy is also fantastic - each gem and rock is well built. The two halves of each rock are perfectly conforming and not janky (if you know what I mean). This is truly one of the best quality toys we’ve gotten for our little one. I cannot recommend it enough.

Fun toy and lovely quality
My boys love these. Really good quality, some small gems which I need to keep away from baby sister but otherwise they keep coming back to these. Very much enjoy smashing them and seeing what colour gem is inside or which shape they will get.

Un set diverso dal solito
Questo set della Learning Resources è veramente ben ideato. In pratica sono 8 “pietre” tonde con all’interno ciascuna una pietra preziosa da aprire con martello e scalpello. Devo dire che è veramente originale e diverso dal solito, tanto che mia figlia ci gioca tantissimo. Io nascondo per la casa le pietre e lei fa finta di essere un archeologa e le va a cercare. Una volta trovate si diverte un sacco ad aprile una per una per scoprire quali pietra preziose sono racchiuse all’interno. Insieme nel set è compresa anche una comoda borsetta di tela in modo da poter riporre all’interno tutti i pezzi del set e non perdere niente. Nel complesso lo trovo ben realizzato ed il prezzo attuale, di circa 28 euro, mi sembra ber rapportato alla qualità stessa del set. Io personalmente lo consiglio, soprattutto per la sua originalità.

Fun gem mining set good for fine motor!
My kids love this set so much! They enjoy using the hammer and pick to open the gems. They find it so fun to find the gems or the ‘treasures’ as they call it and matching them back to rocks and closing them up. These are pretty strong as my children really beat on them with the hammer lol! A win for moms.
