50 mini glass gems. Gems range in size from 3/8" to 9/16" in size. All gems have flat bottoms.Picture does not do gems justice. Gems are brighter and shinier than picture depicts. Any visible marks are glare from the camera lens.I take my photographs as true to actual color as possible. However, computer monitors vary widely, and the same image may not appear identical from one monitor to the next.Please take note of gem size. Pictures may show tiles larger than they actually are.
