Just opened a case and found these glass tubes of opals. When I was casting I used them for mosaic pieces. I acquired them at the Tucson Gem show in the late 89's. I actually have no clue what to do with them now. My fingers and eyes just can't do that kind of work anymore. You will get 9 different tubes. Each are sealed. Some might be dry - some wet. Hope they can find a new home. They measure 3" long. These Australian opal chips are perfect for collectors, crystal lovers, craft projects and as a thoughtful gemstone gift.
