3/8" or 10mm Glass Gems, approximately 120-Pieces Per Bag

Glass Gems are sold by description rather than pictures. Because the pictures may not accurately portray the product depending on the browser your computer uses. We describe the product in the best manner we can and do not warrant that the color we describe will be as you might describe it. A nugget or marble that is "shiny/iridized/metallic" means that it has a "slight" mirror like coating on the surface that gives a silver or gold type finish. This coating may not show well on the displayed image.

SIZE AND MEASURMENTS All measurements are approximate.
