Crystals, Rocks, and Gemstones : Exploring Earth's Treasures

Crystals, rocks, and gemstones: exploring earth's treasures is an illustrated guide by Kelsey Oseid, author of What We See in the Stars, that introduces readers to more than eighty minerals, rocks, and gems.

With a full-colour illustration accompanying nearly every entry, the book explains how different stones form deep within the earth, what gives gemstones their distinctive colours, and how precious stones like diamonds are valued.

It also delves into the cultural and historical fascination humans have long held for crystals, from fossils shot through with iridescent opal to the ancient Egyptian belief that emeralds protected the dead in the afterlife.

Aimed at rock hounds, collectors, and curious readers of all ages, it combines natural history with folklore and practical, everyday appeal.
