This striking red mercury glass Christmas ornament displays the rich, luminous glow that collectors prize in early holiday glass. The heavy spherical globe reveals a dramatic crackle interior silvering, creating layers of ruby depth that shimmer beautifully in natural or tree light. Its substantial weight and thickness distinguish it from later reproductions, while the warm patina of the mercury finish gives the ornament a timeless, old-world presence. Finished with a classic silver metal cap, original hanging ring, and decorative chain, this ornament reflects the craftsmanship of early to mid-20th-century mercury glass production. Exceptionally reflective and well-preserved, it remains in excellent condition, with no cracks or losses noted. A stunning statement piece for a curated Christmas tree, bowl display, or mercury glass collection – elegant, authentic, and increasingly difficult to find in this size and color.
