Women's thumb rings can be traced back to ancient Rome, where it was fashionable to adorn all five fingers with multiple rings. Julia Roberts helped revive the style when she wore one in the 1991 movie "Dying Young," according to rings-4-u.com. Women wear thumb rings for a variety of reasons.

Style

The thumb's size, thickness and strength (it's the strongest finger on your hand) makes it ideal for wearing rings that have thicker bands or are oversized.

Extra Display Area

Women who like to wear a lot of rings put them on their thumbs because it's one more finger they can use for displaying their jewelry.

Male Partner's Ring

A woman who wears a ring belonging to her boyfriend or a widow who has her husband's wedding band may put them on their thumbs since it's wide enough to hold the thicker band.

Trend

Fashion-conscious ladies will wear thumb rings if the trend experiences a resurgence in popularity.

Sexual Orientation

In the 1990s, it became a trend for lesbian and bisexual women to use the rings as a sign of their sexual orientation.

Individuality

Since many ladies don't typically place a ring on their thumb, individual- or nonconformist-minded females use the jewelry to express their personalities.
