Hi guys,
A chapter of the book I'm reading is titled 夜光石のひみつ。
Can someone please tell me how to pronounce this reading and what it is?
よろしくお願いします

やこうせき

Also known as 蓄光石

Glow-in-the-dark stones.

I just every bit of that by googling to make sure I had guessed the correct reading.

The most impressive cases of natural phosphorescence (if it continues to glow after you take the energy source away, it's phosphorescence) are UV-activated and emit in the visible light spectrum, so you need a blacklight.

My husband collects minerals and has a few (stuff like fluorites and calcites, which are actually quite common and cheap).

The Natural History Museum in London has (had?) an exhibit in the jewel vault which contained a whole range of different coloured diamonds, some of which are phosphorescent. That's pretty impressive.
