Minor Mutations in Gems (by Disgustedorite)

Minor mutations seen in Gems are unusual but harmless features that might come up in a Gem's physical form as a result of a change or mutation in her gemetic information before she emerged from the ground. Some (but not all) of these conditions are named after similar conditions seen in humans and animals, but are not biologically the same.

Minor mutations do not significantly affect a Gem's mannequin or her ability to work. They are only visible in the physical form, and the gemstone will look the same whether she has the mutation or not.

More of these will be added as I come up with them. If you wanna make a Gem who has one of these mutations, go ahead.

Albinism and Leucism
Named for their similarities to the conditions seen in humans and animals, these present in Gems as an inability to have darker colors in their physical forms.

An albino Gem can't have colors that are darkened from her base color. For example, an albino Amethyst would not be able to have black or purple that's darker than her gemstone anywhere on her form.

A leucistic Gem can't alter any of her colors to anything darker than her base color, usually has faded colors overall, and can't add tints to her colors. For example, a white Pearl (such as canon Pearl) who's leucistic can only have light peach or white in her color scheme and can't have anything tinted blue, green, yellow, or any other color.

Melanism
Despite the name, melanism in Gems has nothing to do with melanin because Gems don't have that. However, its effects are the same: The Gem who has this condition will only be able to present colors much darker than her base color, and her skin tone will be much darker than her gemstone as well.

For example, a melanistic Amethyst will be entirely black and dark purple.

Melo Syndrome
Named for the first Gem observed to have this condition, a Melo Melo Pearl. Gems with Melo Syndrome have short hair completely covering their skin.

If the Gem would naturally have markings on her skin, the color of the body hair varies in those areas; for example, if Jasper had Melo Syndrome, she would have mostly white hair that changes to a more orangish-pink color over where her markings are.
