Vintage synthetic quartz crystal grown circa 1940s, showing the long hexagonal form typical of early hydrothermal production. These pieces were originally created for industrial and radio frequency applications before gem use became common. The clarity, crisp prism faces, and internal growth zoning reflect the pioneering quartz synthesis of the mid-20th century.
