Product Description

Pristine diamonds, radiant rubies and sapphires, and other gorgeous gems captivate us with their extraordinary beauty and brilliance. But beyond their aesthetic appeal, the gems, minerals, and rocks of the world are essential to our very existence; they are the building blocks of the universe. This quiz deck presents a well-rounded sampling of mineral lore in a Q&A format, with a question—often accompanied by a color photograph—on the front and the answer on the back of each of the forty-eight cards. Together they offer a fascinating tour of the mineral kingdom, from the legendary Hope Diamond to corals and cultured pearls, dazzling crystalline caves, and the mysterious sarsens of Stonehenge.
