In Summary:
Meet Sarah, a real-life stone detective and explorer! Sarah has a very cool job- she is a gemmologist, which means she is a scientist who has special training to identify different types of gemstones. She is also a lapidary, which is a fancy word for someone who cuts, shapes, and polishes stones to make them into beautiful jewellery.
Here are some amazing things about Sarah and the special stone she studies called Whitby Jet:
• It’s Fossilised Wood: Whitby Jet isn’t just a regular rock; it is actually fossilised planks of wood that have been stuck in the cliffs for millions of years. When the sea washes the cliffs away, the Jet breaks off and the tide carries it onto the beach for people to find.
• More Mysterious than the Moon: Even though Jet is found right here in the UK, Sarah says we actually know less about Whitby Jet than we do about rocks from the moon! She is doing a lot of scientific research to help everyone understand it better.
•Sarah says her job is like being Indiana Jones because she gets to have adventures. She explores old, abandoned mines and travels all over the world, to places like Arizona and Turkey, to talk to other people who love gems.
• You don’t have to be a grown-up to start being creative. Sarah made her first piece of jewellery to sell when she was only 11 years old! By the time she was 14, she was already selling her crafts at fairs in York.
Sarah doesn’t think there is a big difference between being a scientist and being an artist; she uses her imagination for both. She even went to university to study geology (the study of rocks) because she loved stones so much and wanted to learn their secrets.
Think of a gemmologist like a “Nature Detective.” Just like a detective uses a magnifying glass to find clues at a crime scene, a gemmologist uses science to look deep inside a stone to find out its secret history and where it came from!
