Blue Marble National Geographic Gemstone Advent Calendar - 24-Day Set with Dig Brick & Jewelry Settings

The Blue Marble National Geographic 2026 Gemstone Advent Calendar is a 24-day countdown that reveals a different polished gemstone each day, plus a final mini-dig rose quartz crystal and jewelry settings for creative play.

Turn December into a hands-on geology lesson with a gem revealed each day. This special-edition advent calendar includes 24 polished stones selected to showcase a variety of colors and textures, a collector's pouch to secure the collection, five jewelry settings to make wearable pieces, and a small excavation brick hiding a larger rose quartz on the last day. Designed for curious kids, the set blends unboxing excitement with tactile learning and imaginative crafting.

What kinds of gemstones are included and how varied are they?

The calendar offers a curated assortment of polished gems chosen for visual contrast and educational value. Expect a range of colors, patterns, and mineral types so children can compare properties as they collect.

• Includes stones like agate, green aventurine, hematite, sodalite, turquenite, tiger's eye, and blue calcite.
• 24 individual pieces, each uniquely colored or patterned for easy identification.
• One larger rose quartz hidden in a dig brick as the final reveal.

How does the mini-dig feature work and what does it teach?

The final day conceals a rose quartz inside a small excavation brick that children chip away to reveal the crystal. This simulates basic fieldwork techniques and encourages patience, observation, and fine motor coordination.

• Includes a compact dig brick and simple tools for safe excavation.
• Hands-on removal mimics geological discovery without complex setup.
• Promotes attention to detail and step-by-step problem solving.

Can kids make jewelry with the gemstones and what supplies are included?

• Five bezels/settings compatible with the polished gems for necklaces or charms.
• Collector's pouch stores completed jewelry and loose stones safely.
• No additional tools required to assemble simple pieces right away.
