Emeralds are typically found with natural internal fissures which are known as “gardens”. Long ago it was discovered that the simple application of oils would greatly reduce the visibility of these inclusions, thereby noticeably enhancing the emerald’s appearance. This practice has become traditional and is accepted throughout the precious gem trade. Emeralds are also known to be not quite as durable as diamond, ruby and sapphire. This fact combined with the common practice of oiling requires the owner to take a little extra care of their wonderful green gems.
