Emeralds are often characterized by a garden of included crystals trapped within, known as the "jardin", because under magnification you will see all sorts of lovely patterns resembling foliage in a garden.

include crystals, tiny bubbles representing small minerals that were absorbed into the diamond while it was growing; pinpoints, crystals so tiny that they only appear as little dots under 10x magnification; needles, needle-shaped included crystals; ...

Since diamonds are resistant to acids, the solution actually dissolves the included crystal while leaving the diamond completely unharmed. The end result is a more transparent diamond.

Quartz containing large included crystals of rutile or tourmaline is often more valuable than quartz without. Characteristic "horsetail" inclusions are preferred in demantoid.

Common natural spinel inclusions include 'spangles' which are included crystals with surrounding iridescent stress fractures. Other common inclusions are octahedral crystals or cavities filled with calcite or dolomite.

Not only are the crystals likely to affect the clarity grade of the gem, they also can be suggestive or diagnostic of its species, enhancement status, or location of origin. Included crystals with rounded, rather than sharp edges, ...

Examples of liquid or gaseous inclusions may be water or carbonic gas, with sometimes a bubble of gas in the liquid (a 'two-phase inclusion'), and sometimes also an included crystal (a 'three-phase inclusion').

VS : This stands for Very Slightly Included and these stones are characterised by minor inclusions which are somewhat easy to see under 10x magnification but usually invisible to the unaided eye. Typical inclusions may be small included crystals, ...

Since the softest directions available for sawing and polishing are used by the cutter, and since included crystals have a different orientation from the surrounding mass, they almost always have a harder direction than that being exploited.

However, the very finest reds are so rare that some clarity defect is almost always present (usually fractures). Included crystals are quite common in spinel. Many stones display natural iron-oxide stains in their fractures.

The Indian sunstone shows a coarser sparkle in the shiller that is present in the stones when compared to the Oregon stones. It is said that the source of the shiller in the Indian stones are included crystals of Hematite.

Inclusion, an inclusion within a gemstone is an internal flaw, or included crystal, bubble, cloud, graining, fracture, etc.. Inclusions are differnt from blemishs, which are imperfections at the surface of the gemstone.
