Is it permissible to a woman to wear an eyebrow ring?

A woman may adorn herself with permissible things, whether
that is gold or silver, or other types of jewels. 

She may adorn herself with them however she wants, but there
are conditions for that, which include the following: 

–        
It should not be an imitation
of kaafir or immoral women.

–        
It should not be done to look
weird or stand out; rather it should be done in accordance with the custom
of women in her country.

–        
It should not cause any harm.

–        
It should not contain any image
of animate beings. 

Ibn Qudaamah (may Allah have mercy on him) said: It is
permissible for women to adorn themselves with gold, silver and jewels
according to their custom, such as bracelets, anklets, earrings and rings,
and what they wear on their faces, necks, arms, ears and elsewhere. As for
that which is not customary for them, such as some types of belt and the
like, which is specifically for men, that is haraam, as is also the case if
a man were to adopt women’s adornment. End quote. 

Al-Mughni, 2/325. 

Shaykh Muhammad ibn Ibraaheem (may Allah have mercy on him)
said: 

Islam, in its wisdom, permits women to adorn themselves in
customary manners. End quote. 

Fataawa Muhammad ibn Ibraaheem,
4/73 

Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) was asked
about the ruling on piercing a girl’s ears for the purpose of adornment. 

He replied: The correct view is that there is nothing wrong
with piercing the ears, because this is one of the means of permissible
adornment. It is proven that the women of the Sahaabah had earrings that
they wore in their ears, and this pain is mild; if it is done when the child
is small it heals quickly. 

With regard to piercing the nose, I do not remember any of
the scholars saying anything about it, but it is a kind of mutilation and
deforming the features as far as we can see, but there may be others who do
not agree with that. If women in a country regard putting jewellery in the
nose as a kind of adornment and beautification, there is nothing wrong with
piercing the nose in order to put jewellery in it. End quote. 

Majmoo‘ Fataawa wa Rasaa’il Ibn ‘Uthaymeen,
11/92 

The same may be said about putting a ring in the eyebrow. If
that is the custom of Muslim women in your country and it does not cause any
harm, then there is nothing wrong with it. 

It should be noted that women are forbidden to show their
adornment in front of non-mahram men. If she puts this ring (in her eyebrow)
she should only show it in front of other women, her husband and her
mahrams. 

And Allah knows best.
