About how big are the rock samples?

About the size of walnuts. Not very big, but big enough if you are just showing your kids the different rock types. Nice set to receive as a present for a grade-schooler. That's what we used the set for a few years ago and we pull them out when we have a rock talk.

The stones are not flat but they fit well in the palm of the hand for massaging. I bought medium, large and extra large. The medium stones are about three inches. The large stones are aproximately four inches. The extra large rock is approximately five inches and very appropriate as a sacral stone.

They are the size of a small pebble. So bigger than normal fish rocks/gravel. Sooo much easier to deal with AND clean.

I believe they are the inside of the rock, but the rock itself is completely hollow so there isn't much difference. We have it covering a well pipe and there is plenty of room to spare.

They were about the size of an old half dollar coin. Or you could say about the size of a golf ball as well. I hope this helps you.

It's easier to measure them in centimeters. They are 1/4 cm, 1/2 cm and 8/10 (4/5) cm. The sieve is 11 inches across. I have a larger one for bigger rocks. Glad to hear about the worm separation idea. I never get all of the little guys out of the composted material!

I ordered these stones for my son--he had them on his wish list. That was several months ago, and I believe they're close to the size of ice cubes (since you use them in place of ice cubes), but I didn't really look at them before wrapping.

Very small. We used them for science experiments. About the size of two small cupcakes.

They are fairly large pieces. I measured a few 7 in by 4 in and 5 1/2 by 4 inches.

That's the range for the lion's share of the pebbles. I've seen a few that were very small (say around 4 mm or so) and almost none are larger than 16mm.

Hi there. This was a gift for my nephew. If i remember correctly...they were light-weight and perhaps the size of a marble. Hope this was helpful.

Love this set, but was expecting it to be much bigger, especially for the cost. its more like a travel set. The stones are 3/4 inch. Board is about 12"x 10"

The size of the gravel pieces vary from 2mm to 4mm, the color is the same as the picture

j. ; hi do not have one of the clear glass files in front of me, but they are pretty small. I am thinking only 1 mL. if you would like me to, in about six days I will be able to get back with you with an extract size.
