Birthday Jewellery Gift Ideas for a 21st, 30th and 40th

A milestone birthday deserves something that is still being worn a year later, long after the cake and the photos. Birthday jewellery does that better than most gifts, as long as it suits the way she already dresses. Here is how we would think about a 21st, a 30th and a 40th, though any of these would work for any age.

Before you choose

• Notice what she wears now. Gold or silver, small or bold, lots of pieces or one. Buy something that fits beside them.
• Check her ears. If she has pierced ears, earrings are the safest gift there is, because they never need sizing.
• Think about extenders. Necklaces and bracelets with an extender chain can be worn snug or loose, which takes the guessing out of length.

Jewellery for a 21st birthday

A 21st is often when someone first gives her jewellery meant to last beyond a single season. Pick one she can wear to class, to work and out on a Friday.

The Glint Necklace keeps five clear stones gathered at the base of the throat on a 22k gold plated bead chain, small enough for a lecture and still on when the day turns to dinner. It is A$69. For something she can wear with every metal she already has, the Duet Hoops pair 22k gold plated and silver tone halves in each hoop and sit close to the lobe, for A$49.

Jewellery for a 30th birthday

By thirty most people know their own style, so the gift is a piece that sharpens it rather than one that changes it. A necklace that sits high is easy, since it suits an open shirt at the office and on a Saturday.

The Riviera Necklace is half baroque freshwater pearl and half 24k gold plated twisted chain, sitting at the base of the neck, for A$69. If she loves colour, the Celeste Set brings aquamarine and freshwater pearl into two layers with a coin pearl pendant, for A$149, and shipping is free Australia wide.

Jewellery for a 40th birthday

A 40th is a good excuse for one piece with real presence, the one that gets mentioned at dinner. It should be bold enough to wear on its own.

The Heirloom Drops set a flat baroque freshwater pearl above a large 22k gold plated medallion that hangs to about the jaw, for A$69. The Palazzo Choker is a flexible 22k gold plated band that sits high on the throat and bends as she moves, the piece an evening outfit gets built around, for A$89.

Writing the card

A line in the card about why you chose the piece matters more than people expect. Tell her you picked the earrings because she always wears her hair up, or the necklace because it sits where her favourite shirt falls open. It turns a nice gift into one she remembers who gave her.

How to pick between two

If you are torn, picture the last time you saw her dressed up and the last time you saw her on an ordinary weekday. The piece that would have suited both is the one to buy. A birthday gift that only works for the party ends up in a drawer.

A note on price

Every piece in our range starts at A$49, and most sit under A$100, so a thoughtful gift does not depend on the budget. You can see them all in jewellery gifts under A$100.

If she wears the same few pieces every day, our guide to everyday jewellery will help you choose one she will reach for each morning. And if the birthday falls near the holidays, the Christmas jewellery gift guide sorts the range by person and price.
