When your 7-year-old daughter is all about gemstones, crystals, and treasures, there’s no better way to celebrate her special day than with a “She’s A Gem” birthday party! Recently, we threw a glittering gemstone-themed bash that combined geology, creativity, and plenty of sparkle and shimmer for our little gem-loving girl and her friends—and it was a rock solid hit!
Gemstone-Themed Birthday Party
This was a gemstone-themed birthday party to remember complete with smashing geodes, creating habitats for pet rocks, and decorating gemstone crafts! Here’s how we turned our home into a sparkling gemstone wonderland and made memories that glittered just as brightly.
Geode Cracking
We kicked things off with a bang—literally! Each guest got to crack open her very own geode. The girls were wide-eyed with excitement as they donned goggles and hammered their mysterious rocks. As the geodes cracked open to reveal their glittering crystal interiors, the “oohs” and “aahs” filled the air. It was part science, part magic, and 100% fun.
Each girl got to take her geodes home as a treasure from the day, sparking some new rock collections in the process!
Adopt-a-Pet-Rock and Pet Rock Habitats
Next up, I had set up a fun “Adopt-a-Pet-Rock” station, where each girl was able to chose a silly pet rock to adopt and then decorate a little jar “habitat.”
I made the pet rocks in advance, but had the girls been a bit older – maybe 9 or 10 years old – I would have had them make the rocks themselves. Each rock was a geode slice and had googly eyes and either pom balls or chenille pipe cleaners for hair.
Originally, I was going to use the geode slices to make necklaces, but then I discovered the geode slices made for perfect pet rocks with a LOT of character!
Then they decorated their habitats with great care! The girls were able to craft perfect pet rock homes by customizing jars with tiny hand-sewn cushions, paintings, tiny books, a donut, a boba, and a squishmallow. I even hot glued tiny twist on lights on the lights to give the pet rock habitats a “lamp.”
The girls then named their rocks and wrote little certificates about their pet rocks’ favorite things.
This imaginative activity gave everyone a chance to be creative while giving their new sparkly “pet” a comfy and stylish place to live.

Pass the Parcel
Thanks to Bluey, no birthday party is now complete without a classic game of Pass the Parcel! I wrapped up gemstone-themed trinkets—think rock bead bracelets, a tiny crystal collection, and gemstone digging kits—in layers of tissue paper. As music played, the parcel made its way around the circle of giggling kids. With each stop, a new surprise was revealed. Obviously, we did NOT play using Lucky’s Dad’s rules.
The excitement grew with each unwrapped layer, and the girls would chant the name of the girl is “landed” on as she opened her layer to discover her prize.
Rhinestone Headband Crafting
Then it was time to shine! At the crafting table, each girl received a plain fabric headband and access to bowls of colorful rhinestones, gems, and glitter glue. The girls designed headbands that dazzled—some elegant, some wild, all uniquely fabulous.
It was a perfect wind-down activity that doubled as a party favor and a wearable reminder of the day. At school pickup, I still see some of the girls wearing their headbands months later!
A Sparkly Surprise for the Birthday Girl
Before cake, the birthday girl opened her presents. This year, she had one special wish: earrings for her newly pierced ears! (Ok, maybe it was MY special wish because I can’t deal with anymore toys in my house.) Her friends and family delivered big time! She unwrapped a whole collection of earrings—studs shaped like hearts, stars, and even tiny crystal pizzas. She was absolutely thrilled and she cannot wait for her piercings to heal so she can try them on.
We normally don’t open presents during the party, but I’m so glad we did this time because the girls loved watching Wren open her presents to see the joy on her face!
Rock Candy Cake & Geode Cupcakes
Finally, we gathered around for birthday cake! The cake featured rock candy “crystals” and sprinkles. It was almost too pretty to eat… almost. And the cupcakes for the guests had edible gemstone toppers!
With happy tummies, sparkly crafts, and treasured memories, the party wrapped up with smiles all around.
This gemstone-themed party wasn’t just about shiny rocks—it was about joy, discovery, and celebrating our very special girl in a way that reflected everything she loves.
Looking to throw your own dazzling celebration? Just remember: a little creativity, some gemstones, and a lot of love go a long way toward making any birthday truly brilliant.
