A 21st birthday is a special milestone and special gifts like jewelry are perfect for the occasion. A 21st birthday gift should be thoughtful and personal.
Casual jewelry including charm bracelets, bangle bracelets, watches, anklets and earrings are great gifts for a girl's special day.
Young women also enjoy thoughtful gifts such as a collage created about them, a card with 21 dollars in it or being taken out for dinner and drinks.
Other ideas include gift cards to her favorite hair or nail salon, spa, restaurant, movie theater or store. Picture frames, photo albums and jewelry boxes are also appropriate gifts for a woman who is turning 21 years of age.
