Lovely fun toy
Lovely design to them, with the colourful gems in the rocks. Great for learning colours and shapes. Can play a few different sorting games with them. Easy to tap open, very fun.

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.

Rock n Gem Surprise
Excellent toy that provides hours of play for my 2.5 year old. Helps them work on their fine motor skills, shapes, colours and role play! Definitely recommend.

Meh gems
Beloved but for the price I feel the “gems” could be better quality. I will probably be swapping them out for something sturdier or prettier.

Great fun and educational too.
I purchased these for my four year old as a Christmas present and they’ve been a huge hit. They’re larger than I expected which is great as I think they would be harder to crack open if they were small. My two year old has discovered that if you throw them on the floor hard enough, they do pop open (I am trying to discourage this, but toddlers are so strong-willed). My four year old loves the fact that you get the coloured gems inside. Educationally speaking, it’s great for fine motor and colour matching.

My son loves these crystal rocks, out of all the toys he got for his birthday (which was A LOT) this was by far his favourite!
