Pearl Hairpins

"We wore white crepe dresses trimmed with satin ribbon & the bodices & sleeves spotted with white beads. . . Thursday night, Pearl combs, necklaces, earrings, & brooches. . . Tuesday evening we had sprigged muslin. . . gold ornaments & flowers in our heads & Friday we wore yellow gauze dresses over satin, beads in our heads & pearl ornaments" 
Fanny Knight Austen

Threading pearl beads through their hair was one way that Regency ladies adorned themselves for an evening or formal event.  You can easily achieve a similar effect using pearl adorned hairpins like these (sold as a set of two). Hairpins measure 2.25" long and have a gemstone accent in the center.
