We walk past rocks almost every day without thinking much about them. But sometimes, when we’re at a beach, on a mountain trail or scrolling through TikTok Lives (yes, rock collection videos are a thing), we find ourselves called to take a closer look; maybe pick something up and save it for later.
Over time, you end up with a little (or large) collection. Whether yours is made up of pebbles scooped up from the beach that have been living in the bottom of your tote bag since the last time you visited the coast, or perfectly polished and tumbled crystals that you’ve purchased from an Etsy witch online, they could contain minerals that crystallised millions of years ago. Those rocks might have been transformed deep underground in an epic mountain-building event, spat out by a volcano, or even transported for miles by a glacier before they made their way to you. I think that the history beneath our feet is part of why we feel so oddly connected to some of the rocks we come across.
If you, like me, are drawn to the more colourful rocks out there, you’ve probably come across some of our favourite crystals: Citrine, Rose Quartz, Amethyst. In spite of their distinct appearances, they’re all composed the same, made up of Silicon and Oxygen (SiO₂) in an ordered lattice. What makes them different is the presence of trace elements like iron, microscopic inclusions (any material that gets trapped in the rock as it’s forming) or even some natural irradiation. It’s teeny changes in chemistry or geological conditions that can transform rocks and crystals made up of the very same things into something much more special.
Their chemistry and appearance are a record of the geological environment in which they were formed. Obsidian’s pure black and glassy exterior tells us it cooled quickly after a volcano erupted. Marble contains calcium carbonate, so we know it begins life as limestone (or dolostone), formed from the accumulated remains and shells of ancient marine organisms, before heat and pressure transform it into something new. In looking at rocks, we can unlock and read part of the earth’s story, and I think it’s pretty cool that we can collect a little piece of that too.
Rocks and crystals have been a part of our lives as humans as far back as the Stone Age, where early humans used stones to make tools, or even start fires. Since then, those same rocks have been used to build monuments and other great symbols of culture; precious stones became a currency and a source of status, and even now, diamonds remain a girl’s best friend. Our relationship with rocks has shifted throughout civilisation, but has never disappeared. Perhaps, there’s something reassuring about holding something much older than ourselves. Holding something that’s survived maybe millions (or billions!) of years of geological change offers a little perspective.
Beyond that, collecting rocks is also a way of collecting memories. That pebble is no longer just a pebble, but a reminder of the beach you visited and the moments you shared wandering along the coastline; it’s a small and tangible connection to a moment in time. Searching for the right rock, or combing the beach for fossils, also encourages you to slow down, taking a closer look at the natural environment and the world around your feet that our day-to-day lives doesn’t always allow.
So, whether you believe that your crystals have healing properties, or simply enjoy how they look on your windowsill, our fascination with rocks has been enduring. They’re little pieces of natural history, reminders of places we’ve been, and an invitation to slow down and take a closer look at the world around us. Which, I think, gives you permission to not cut down your rock collection!
