100 PCS Acrylic Crystal 20mm Round Diamond Crystals Treasure, Chest Hunt Party,Vase Fillers, Event, Wedding, Birthday Decoration Favor. (100)

I've included a picture of the gems next to a ruler as well as show the height in a calliper. The gems don't have a diameter or a height of 20mm as indicated in pictures (the gem shown in a palm in the description when I bought was laughable. The gems, however are a nice size for what I needed, so the smaller size was okay for me. They are about 12mm tall and about 18-1/2 mm in diameter. Color mix was 7 colors and random as expected. Quantity for me was about 101, which with an expectation of 100 is good. I have no complaints as shown by the 5 stats, but again, the smaller size worked for me.

As expected.

Good quality

I used these for game pieces for my classroom and my students loved them!

Nicely put together. Good coloring assortment. Solid plastic. Good size. About the size of a penny. I’d buy again.
