The Isle of Mull has a way of capturing your heart, not just with its dramatic landscapes and abundant wildlife, but with the hidden treasures found along its shores. For many visitors, myself included, the simple act of beachcombing becomes a cherished part of the island experience. And among the shells and fascinating pebbles, nothing quite sparks joy like the smooth, frosted gems of sea glass.
I’ve spent countless hours exploring Mull’s unique coastlines, and places like Carsaig, Balmeanach (specifically the shore just before Mackinnon’s Cave), and Java in Craignure have become particular favourites for uncovering these ocean-tumbled jewels. What I’ve found across all these locations is a consistent array of colours: white glass is the most popular find, followed by greens, and then the more coveted blues, yellows, and reds/oranges. While some might think of crafting with sea glass, for many of us, the true magic lies in the discovery itself, and then finding beautiful ways to simply display these beautiful pieces of Mull’s history. Like many collectors, I have a vast collection of all colours, proudly filling large jars, and I want to share how you can cherish your own finds too.
The Pure Beauty of the Naturally Transformed Treasure
What makes sea glass so captivating isn’t what we turn it into, but what the ocean has already done. Each piece is a fragment of history – perhaps from an old bottle, a forgotten fishing float, or even a shipwreck – tirelessly tumbled and smoothed by the waves and sand for decades, sometimes even centuries. The result is a unique piece of frosted beauty, a testament to the raw power and artistry of the sea. There’s a profound satisfaction in finding these naturally polished gems, knowing they are perfectly complete just as they are. This commitment to only collecting those pieces that are absolutely, completely smoothed by the waves is part of the deep respect I have for the ocean’s ongoing artistry.

Common along Mull’s shorelines, green and white sea glass are fragments of discarded bottles and jars.
The Art of the Sea Glass Search
My approach to discovering Mull’s best sea glass often involves seeking out a very specific kind of beach environment: the high tide mark on pebble beaches where the larger stones gradually give way to a finer, grit-like substance. This is the ‘sweet spot’ where the ocean frequently deposits its treasures, protecting them just beneath the surface.

Decades tumbled by tide and stone—each shard once sharp, now softened into treasure.
When I find this ideal zone – whether it’s at the rugged, wild shores of Carsaig, the quietly rewarding shore of Balmeanach (especially just before the famous Mackinnon’s Cave), or the Java area in Craignure, facing the Sound of Mull – I love to pick a spot and settle in. This is where the true search begins, not with a frantic dash, but by gently raking through the grit with my fingers. It’s a slow, methodical process, but incredibly rewarding as the glint of frosted glass emerges, revealing colours you might have otherwise missed. And crucially, I adhere to a personal rule: I only ever take a piece if it’s totally smoothed. Any other fragment, no matter how intriguing its colour or shape, I leave nestled in the grit. It’s a hopeful thought that perhaps in another ten years, Mull’s tireless tides will have worked their magic, and I’ll find it again, perfectly polished. Each of these three locations offers its own unique character for this mindful search, often yielding different hues and forms of glass.
Classic & Elevated: The Art of Display

A simple jar with your best pieces of glass can look good anywhere.
- Vary Your Vessels: Instead of just one type of jar, experiment with wide-mouthed apothecary jars, elegant cylindrical vases, or even large glass bowls. Different shapes can highlight different aspects of your collection.
- Group by Colour or Origin: Try dedicating a jar to only blues and greens, or creating a vibrant rainbow jar. For a personal touch, you could even have distinct jars labelled “Carsaig Finds,” “Balmeanach Gems (from Mackinnon’s Cave),” and “Java (Craignure) Jewels,” allowing your display to tell the story of your island adventures.
- Layer with Light: Place a small string of battery-operated fairy lights inside a larger jar for a magical glow, especially in the evenings.
Beyond the Jar: Alternative Ways to Showcase Your Treasures

Backlighting your sea glass is a great way to display their colors and beauty.
- Shadow Boxes (Open or Closed): Arrange your favourite pieces in a shadow box. You don’t need to glue them down; simply placing them allows for rearrangement and appreciation of each piece. Some shadow boxes have multiple compartments, perfect for sorting by colour or origin.
- Decorative Trays & Platters: A beautiful wooden, ceramic, or metal tray can become a stunning base for a free-form sea glass arrangement. This works well on coffee tables or shelves.
- Minimalist Bowls & Dishes: Small, aesthetically pleasing ceramic or glass bowls can hold a handful of prized pieces, turning them into elegant desktop or shelf accents.
- Natural Vignettes: Combine your sea glass with other treasures found on Mull – smooth pebbles, a small piece of driftwood, or even a handful of sand from the very beach you collected them from. This creates a miniature landscape that instantly transports you back to the island.
Let it Shine: Lighting & Placement Tips for Your Collection

Placed in a simple bowl on the windowsill, the sea glass catches the morning light.
- Natural Light is Best: Place your displays near a window where they can catch the shifting natural light throughout the day. The way sunlight plays through the frosted surfaces is mesmerising.
- Subtle Spotlighting: For evening displays, consider a small, directed LED spotlight to illuminate your collection, highlighting its colours and textures.
- Clear Shelving: If you have glass or acrylic shelves, these can enhance the light play, allowing illumination from above and below.
Bringing Mull Home: Connecting Your Display to the Island Experience
Your sea glass collection is more than just pretty objects; it’s a tangible memory of your time on the Isle of Mull. Each frosted fragment carries the essence of those peaceful moments spent searching the shores of Carsaig, the quiet contemplation near Mackinnon’s Cave at Balmeanach, or the unique thrill of discovery at the Java area in Craignure. It’s a reminder of the patience and respect you offered the ocean, leaving imperfect pieces to be honed by its ceaseless artistry.
As you arrange your finds, let them serve as a beautiful, constant reminder of the island’s wild beauty, the rhythm of the tides, and the unique connection you forged with its coastlines. It’s your own personal piece of Mull, forever cherished.
