In this episode of Facet Nation, Simon and Lucinda delve into the fascinating world of gemmology, focusing on the spectroscope and its critical role in identifying gemstones. They discuss the different types of spectroscopes, techniques for using them, and the importance of diagnostic spectra in gem identification. The conversation is rich with insights into the nuances of color absorption and the practical applications of these tools in the field. The hosts also share personal anecdotes and tips for gem enthusiasts, making the episode both informative and engaging.

Takeaways

The spectroscope is essential for identifying gemstones.

There are two main types of handheld spectroscopes: prism and diffraction grating.

Using a spectroscope can help you understand how gemstones absorb light.

Techniques for using a spectroscope include transmitted and reflected light methods.

Diagnostic spectra are crucial for identifying specific gemstones.

Understanding colour absorption helps in gem identification.

The spectroscope can be used on both rough and polished stones.

Learning the diagnostic spectra of gemstones is beneficial for gemmologists.

The conversation emphasises the importance of practical experience in gemmology.

Future episodes will cover more advanced topics in gemmology.

"We're going to talk about the spectroscope."

"It's a really good one."

"You can't see it, but it's there."
