Months and weeks to do, but well worth the time. Highly recommend for very advanced puzzle doers. I loved it. Just as beautiful when done as it is on the cover.
I enjoyed putting the rocks together mostly and learning each name
I was surprised that this puzzle was easier to put together than I thought it would be.
Money well spent.
This was challenging yet highly enjoyable on account of the white background and the shelf pieces that look alike.
fun for multiple people to pick a color of mineral
I loved this puzzle!
Love these eurographic products. Odd shaped pieces are fun to work. Colors and graphics are beyond excellent.
.Good for a group build because of all its distinct parts. Educational
This puzzle is very difficult due to the various grids. The minerals chosen could have been more colorful. OK, but not my favorite.
Great puzzle for students to do.
