Forget about wearing your heart on your sleeve, strap on a shiny diamond tennis bracelet and call it a new day. Jewellery is an investment that can be passed on for generations, so here are our picks for pieces that every single girl should buy for herself.

1. Jade bangle

Jade bangles are heirloom pieces meant to be treasured and passed on, so choosing one made with high quality stone is important. For a modern take on jade, opt for a piece that’s got that extra something, like this one from Choo Yilin, made with a sakura blossom design.

2. Pendant necklace

A pendant necklace is always chic, and wearing one with a simple black or white t-shirt dresses up the whole look. Wearing it with a low v-neck top also helps to elongate your entire frame. To make a pendant necklace more meaningful, get one to mark a milestone achievement, like buying your first apartment or getting that big promotion at work.

3. Birthstone pieces

Celebrate your birthday all year round by wearing your birthstone; they’re a beautiful way to represent another year around the sun… or in the case of those born in June, another year around the Moon(stone).

4. Tennis Bracelet

Diamonds really are forever when it comes to these bracelets. Opt for one with fewer diamonds to keep things simple and wearable on a daily basis.

5. Diamond Studs

You can’t go wrong with a simple pair of diamond studs; they’re a must-have for any jewellery collection. Choose to go all out, or opt for a mid-range pair. We love this classic set from jewellery icon Tiffany & Co.

6. Pearls

There’s a reason your grandma still wears hers: they’re timeless. Not ready for the string of pearls around your neck (or for the full price tag that comes with real pearls) quite yet? Opt for a funky update like this choker by Mizuki.
