Cement Mosaic Stones? not surface mosaic with grout as other have referenced?

and you dont want to buy Diamondcrete or Flashcrete from a hobby shop?

Well… you can make it on your own: go to home depot and ask how to make cement (dont do quikcrete or sacrete- it gets left around and absorbs moisture and throws off the amount of water you will need).
ingredients;
sand, lye, and mortar or something- my mom makes it herself- it took her years to work out all the kinks- talking to a lot of cement makers.
problem is it takes a lot ot finesse- and you cant keep the extra stuff lyin around due to moisture- you cant pop the stone out for 3 days and it needs constant moisture every hour or so, AND you need to put some sort of rebar or reinforcement if its a big stone or bench.

and if you dont make it right- you dont find out until you pop it out and you did all that glass work for NADA- ugh! so frustrating, i speak from experience.

Diamondcrete/Flashcrete set in ONE HOUR, no rebar needed because it is such a dense and strong mixture. AND SUPER SMOOTH!!

so if you still wanna make you own- go to home depot/lowes and ask the peeps there how to make cement from scratch and tell them you dont want to "just add water" bag.

good luck, seriously! you'll need it!

I would say things in the
brown family: camel, coffee, brown-gray, slate-brown, chocolate;
some in the green family but that gets sticky because not all greens will,
dark blues
Certain reds

Not yellow, violet, purple

Just my humble options
Good Luck
