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.

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!

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.

Great toddler toy
Bought these for my 2 year olds birthday and he LOVES them! His occupational therapist uses them so I knew I couldn’t go wrong. But seriously, such a cute toy and keeps my son actually entertained. The gems are small so you definitely have to keep an eye on smaller toddlers, but I’m sure that’s why the age says 3+. They’re very durable and great quality. My son loves the vibrant colors and shapes.

My kids are obsessed—this has turned into nonstop playtime since we got it. They love hiding other small items inside and discovering them again, which keeps them engaged for ages. It’s great for color matching and really helps with understanding cause and effect in a fun, hands-on way. Educational without feeling like “learning,” and honestly one of the toys they keep going back to. Highly recommend!

This Rock ’n Gem Surprise set has been a fantastic addition to our playtime! My child loves using the play hammer and chisel to crack open the reusable geodes and discover the colorful gems inside. It’s a fun way to introduce sorting, matching, and counting skills, as each gem comes in different shapes and colors. The set also offers a gentle introduction to geology concepts without the mess of real rocks and geodes. The included drawstring bag makes cleanup and storage a breeze. Highly recommend this engaging and educational toy for young learners!

Cute
My son love these! They are cute and easy for my 3 year old to play with. Only downside is it doesn't keep him busy for that long but a fun toy nonetheless.

Die Kinder (2 & 4 Jahre) lieben es, spielen lange und viel damit und üben gleichzeitig Farbzuordnung, Feinmotorik und Handlungsplanung; die Edelsteine sind groß genug, dass sie zwar in den Mund passen aber nicht verschluckt werden können; die Steine lassen sich auf vom Kleinen mit Hammer und Meißel leicht öffnen, Zusammenbauen klappt noch nicht ganz allein, hier hilft aber gern der Große; fährt bei uns sogar mit in den Urlaub, klare Kaufempfehlung; Versand und Lieferung schnell und problemlos;

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.

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.
