Hydrofluoric Acid no longer available in stores or on sale in USA on-line. Fed Govt controls it like dangerous drugs. Unless you are working in a commercial lab or at university lab with environmental safeguards, you wont be able to obtain it.

What would be a good alternative to clean diamonds with to remove surface dirt and attachments? I've got about 40 diamonds from the State Line District to clean up that were panned out of the local creeks. They are not shiny smooth like the one's

I've found from Crater of Diamonds. In fact, at first glance you would think they were a piece of clear quartz until you put them under microscope and perform scratch test on corundum crystal. They all tested 3.5 for specific gravity, but they do not glow

blue under uv, but they do color change and glow faintly red. (which is another color that diamonds glow). They do test positive on a diamond tester. And yes, I am heading back to pan for more come July. The first trip was just one days effort!
