Making marble effect with cement | Mind-blowing results!

This is an experiment to find the best combination and thickness of cement to create the marble effect, making something useful a Cement Weight that has several functions, very interesting.
Observations
It took me a bit to unmold them because I didn't put anything in the molds, maybe it's a good idea to put wax, mold release or something similar. Also, I recommend letting the cement dry in some shade because the sun will make the water evaporate quickly and the surface of the cement will end up rough.

The first one broke because it was weaker, the more water the mix has, the weaker the cement cures.

Thank you for the confirmation I was leaning towards that conclusion :)
