National Geographic gemstone advent calendar with 24 gems

About this product

This advent calendar from Blue Marble carries the National Geographic name and holds 24 polished gemstones, one to find each day. The stones include agate, green aventurine, hematite, sodalite, turquenite, tiger’s eye and blue calcite, and the last day brings a rose quartz specimen. A collector’s pouch keeps them together.

Five jewellery settings are included for turning stones into wearable pieces. The title gives the age range as 8 to 12, while the age line in the specifications says 6 years and up, and the listing calls it a STEM activity. It weighs 0.47 kg. The listing gives no stone sizes or box dimensions.

What to use it for

Find a new stone each day and build up a small rock collection in the pouch. The five settings let a child turn chosen stones into jewellery to wear.

Care and safety

Keep the stones in the collector’s pouch and wipe them with a soft dry cloth. Store the jewellery settings with them so the small parts stay together.
