Stone for crystal

[bunk]

What kind of stone is best for conditioning a crystal glass call? I was going to pick up a stone for sharpening a knife to use but wasn't sure what to get. Should I get the white smooth stone or the grey rougher stone?

Buy a primos slick stick if you like a stone,  personally I really like drywall screen for glass and crystal calls.  Scoot

I use the drywall screen now but wanted to get a stone. I've seen the slick stick before but I would rather just get a stone and I know some use stones for sharpening knives.
