You can take the sharp edges off with wet/dry sandpaper. The higher the number, the smoother it will be.

Hi Shelby,
You can use the same technique on stones. Flat, thin skippers are best to start with.
If you want a larger diameter hole, look for diamond tipped tube drill bits. You don’t need to apply a lot of pressure, let the drill bit do the work.
Have fun!

Jane, Wire wrapping is a good way to keep the roughness off your neck in a pendant. I have also used super glue on rocks. It will smooth over the roughness, but make the glass look shiny. I use it on rocks to make them look wet, don’t know what the glass would look like. It may ruin the look completely. Enjoy the creative process!

If the edges are rough and/or shiny, it is considered not finished. Jewelry quality sea/beach glass is smooth with no sharp edges or shiny bits. It takes decades of rolling around in the water to be shaped into finished glass. The process is part of the beauty of it. Some people tumble their glass. It is up to you but if you tumble it to smooth it, it is not considered true beach/sea glass.

Hi Tammy, a Dremel is a multi-purpose tool that you can buy at hardware, home improvement, etc. stores as well as online (amazon, many jewelry suppliers, etc.). For drilling sea glass you will probably want a diamond drill bit for your Dremel. I’d love to see what you make with the sea glass you drill!

Amazing that I find this. Your name is that same as my late mothers. I am in Cleveland, where are you located? Do you sell your jewelry or just for a hobby?
