Además, esta obra le mostrará el modo de cortar las piedras preciosas, cómo pueden hacerse más sofisticadas mejorando su color y brillo, y cómo efectuar un cuidadoso análisis de todas las gemas, prestando una particular atención al diamante, rubí, zafiro, topacio y a los berilos (esmeraldas, aguamarinas). ¿Sabía que para valorar un diamante existe la regla de las cuatro C? En estas páginas encontrará una descripción de estos cuatro elementos: colour (color), clarty (pureza), cut (corte), carat (medición de quilates). Todas las explicaciones son sencillas, claras y vienen acompañadas de numerosas fotografías en color. Al final del libro encontrará un glosario que le ayudará a entender rápidamente los términos técnicos indispensables. Una obra que le proporcionará las bases profesionales para el comercio de gemas o, sencillamente, para comprarlas en lugares especializados.
