Jardin, French for garden, is a trade word for the mossy, garden-like inclusions typical of emerald.
In more detail
Eye-clean emeralds are rare, so buyers expect some jardin. Inclusions lower value most when they threaten durability or reduce transparency. Many fractures that reach the surface are filled with oil or resin.
