Question 1

What do you do with the leftover brick dust?

Accepted Answer

It can be used as a fine sand for sensory bins, disposed of in the trash, or repurposed as a medium for growing crystals (with additional kits).

Question 2

Does this kit include fool's gold (pyrite)?

Accepted Answer

Not typically—the gemstone selection varies but usually includes amethyst, quartz, tiger’s eye, and jasper. Pyrite is not standard, but some batches have included it.

Question 3

Is this kit safe for a 5-year-old?

Accepted Answer

Choking hazard from small pieces (the fossils and gems themselves). The digging dust can be inhaled. If you supervise closely and have the child wear a mask, it can be done, but the official age is 8+.

Question 4

How is the brick packaged—does it survive shipping?

Accepted Answer

The brick is wrapped in plastic and placed in a sturdy box. Most arrive intact, but a few customers received a cracked brick. The specimens are loose inside, so a cracked brick doesn't ruin the experience.

Question 5

Can you return or replace missing or broken specimens?

Accepted Answer

Yes, National Geographic (Blue Marble) has a responsive customer service. Several reviewers reported receiving a replacement kit when a specimen was missing or the brick arrived crumbled.

Question 6

Is there a video or app to help identify the finds?

Accepted Answer

No dedicated app. The included paper guide has color photos and descriptions. There are many free online identification charts for fossils and gemstones that families use.

Question 7

How long does the brick stay usable if you want to spread the digging over multiple days?

Accepted Answer

The brick can be re-moistened with water and covered with plastic wrap to keep it from drying out completely. Many parents split the dig into 2–3 sessions over a week.

Question 8

Are the fossils fragile?

Accepted Answer

Shark teeth and mosasaur teeth are very durable. The ammonites can be delicate—some arrived chipped. The gems are hard but can scratch each other.
