Examples include feathering, internal crystals, stains, clouds, as well as cutting or polishing errors. Florentine Finish:A type of metal finish achieved by etching or engraving parallel lines into the metal's surface in order to reduce shine.

Flaws and cloudiness (called jardin) are very common in emeralds, so many emeralds are oiled, irradiated, and dyed to improve their look.

People often remark how beautiful a piece looks when they receive it or leave the jewelry store, but over time, the gemstones 'change' and become cloudy or dull. While your piece of jewelry is in the jewelers care, he/she is caring for it.

Translucent, or cloudy, meaning that the stone transmits light, but you cannot see clearly through it.
Heavily Included, meaning that the stone is transparent, but the stone is littered with inclusions, which are very visible without magnification.

Typical flaws include tiny pinpoints, faint clouds, tiny feathers, or internal graining.

Even minute traces of other minerals can change the color or cloud a diamond. That knowledge is relatively recent though.

The second indirect effect is the further knock-on effects of having more cloud condensation nuclei.

As the gas of these primitive elements expanded, gravitational instabilities caused parts to co alesce into huge clouds that eventually became galaxies and clusters of galaxies.

Inclusions typically consist of crystals, clouds and feathers. Crystals are tiny minerals that become trapped inside a diamond during its formation.

Another common type of defect in corundum gems is the occurrence of patches of milky cloudiness within the material.

Most diamonds contain some blemishes (crystals, clouds, or feathers), which can be found inside the stone (called inclusions). Surface blemishes are not considered a major concern, since they can often be polished away.

Inclusions may take the form of dark specks, light-colored planes called "feathers", voids, general cloudiness, and other types of imperfections.
