This is craft quality sea glass. None of this glass is good for jewelry making. This beach glass set consists of pieces that may be broken and chipped, drilling blowouts, odd shapes, shiny spots, or are just too tiny to drill. It is perfect for mosaics - lots of tinies for filling in the cracks, embedding into sidewalks and pathway bricks, some pieces might be suitable for tiny bottles (no guarantees). Maybe you can be creative and recycle it into something really beautiful.
