Can quartz come in green? I need to know so that I know if I can put this green crystal in my fish tank.?
If it is real quartz that is a nice counter top. I would suggest a clear epoxy filler. As it is so small you should be able to get the double hypodermic style from the paint dept of the big box store or from your local hardware store. (1mm is about the size of a push pin head.)
