Blue Goldstone Dice Set is made from aventurine glass, created by adding metallic elements to glass in a low-oxygen environment. Cobalt gives this variation its deep midnight-blue color, with royal blue flecks and silver sparkle that catch the light across every face. Each die is cut and finished with gold numbering for a warm contrast against the dark, star-filled appearance. Goldstone takes its name from the Italian word avventura, meaning adventure or chance, while blue goldstone is often associated with courage and perseverance. Each hand-cut die measures approximately 16mm, and the complete set weighs about 5.6 ounces. Slight differences in color, sparkle, and size may occur as part of the goldstone glass-making process, making every set unique. Glass dice can chip or crack when rolled on hard or rough surfaces, so we recommend using a padded dice tray or soft rolling mat.
