#birthstone

The Prompt Foundry is kicking off 2026 with Bejeweled January!

From their pure aesthetic appeal, to their long-storied symbology and associations, the science of how they form to the uses their varying physical properties lend them to, and of course the rich and often fraught histories they have across human cultures, there's so much to explore when it comes to gemstones in art.

Some common associations for each stone are included in the prompt list as a jumping off point, but those are hardly the only directions to go. Dust off the Steven Universe, Deltora Quest, or Sailor Moon villains obsession you thought you'd moved on from. Look up crystal structures and refractive indexes. Wax poetic about color variations. Draw, write, paint with stone-based pigments, break out the pliers and blowtorch to craft some jewelry of your own—create in whatever medium you're inspired to!

Feel free to combine different days’ prompts with each other, or combine them with other events like this past year's Genreuary! Use your OCs, your favorite characters from media, your own experiences, whatever tickles your fancy.

If you use this list, please tag me here @thepromptfoundry, I’d love to see what you create!

Respond to as many prompts as you want or as interest you, don’t worry about missing or skipping any, or posting your work after the day the prompt is assigned to. Remember, this is supposed to be fun!

If you have any questions or musings, check our FAQ, and if you don’t find your answer, shoot me an ask.

One of the most popular varieties today is blue zircon, a vibrant stone often seen in Victorian jewelry. The Museum’s Mignone Halls of Gems and Minerals is home to one of the largest known blue zircons on public display, weighing 208.2 carats! 💎

In 1967 in the foothills of Mount Kilimanjaro a breathtaking discovery unfolded - violet-blue crystals of the mineral zoisite were found. Their intense color was simply mesmerizing, instantly elevating zoisite to a gemstone of paramount importance. Just a year later, Tiffany & Co., recognizing the gem's extraordinary beauty and exclusive origin, christened it tanzanite, a tribute to its East African birthplace. Since then, tanzanite's popularity has skyrocketed, captivating hearts and minds with its unique allure...
