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.

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.
