    Inclusions in Spinel • An Exercise in Aesthetics

    To the jeweler, spinel is famous for its vivid colors. But for the gemologist, this gem is unlike any other. Its extreme hardness allows a fine polish. Couple this with single refraction, which eliminates the image blurring found in most other gems, and a varied landscape of inclusion subjects, and the result is an unparalleled canvas of delight for the photomicrographic artist.

    Terra Spinel takes readers into the world of spinel through the lens and collection of renowned spinel dealer, Vladyslav Yavorskyy. Some of the world's finest spinels are featured in this book's pages as Yavorskyy travels to the most important locations. The traditional sources Burma (Myanmar), Tajikistan, and Sri Lanka are covered in detail, along with newer finds in Vietnam, Tanzania and Madagascar. This is not a gemology book in the traditional scientific sense. Instead, what it represents is a celebration of a rare gem and the places from which it comes. Stunningly illustrated, it is a must-have for any gem lover.
