The famous late gemologist and author John Sinkankas writes in "Emeralds and other Beryls"- considered to be the ultimate authority on the gemology of emeralds - that "a cat's eye in an emerald was the rarest of all," and that so few of them have ever been found that they are considered to be "virtually non-existent." This extremely rare phenomenon in the beryl species might be observed only once in a lifetime, even by gem cutters familiar with emerald crystal structures.

This 4.32 carat fine quality cabochon is from the world renowned Muzo mine in Colombia and displays the classical blue-green hue and intensity of fire associated with that particular emerald source. This unique combination of qualities will be appreciated by the serious gem collector. The combination of large size and fine quality seen in this emerald establishes its place in the Marcial de Gomar Collection of emeralds. Its name is reminiscent of Mr. Marcial's encounter with a jaguar in the rainforest of Colombia as a young emerald miner.

Note: Due to the inability of current technology capturing the blue green hues and light dispersion in emeralds accurately, digital and particularly print images, do no justice to the true beauty, color and fire of Colombian emeralds. These magnificent specimens truly need to be seen with the naked eye to be appreciated to their full extent.
