How to Find Sea Glass in Cornwall - A Local's Tips

If you've read my guide to sea glass and what the colours mean, you'll know this obsession started young, growing up in Newquay, beach walks with my mum, coming home with pockets full of frosted glass before I even really understood what it was. 

 

That blog covers what sea glass is and how to identify what you've found. This one is about the bit that comes before all of that. How to actually find it in the first place.

 

Conditions matter more than location

 

The best conditions by far are the morning after a big storm. When the Atlantic has been rough overnight it churns everything up and pushes fresh deposits onto the shore, pieces that might have been sitting just out of reach for years suddenly appear right at your feet. If there's been a proper swell, set your alarm and get down early before anyone else does. That window between the storm settling and the next tide coming in is when the beach gives the most.

 

Low tide is the other non-negotiable. Check your tide times before you go. When the water pulls all the way back it reveals parts of the beach that are usually submerged, tucked-away areas that rarely get searched. The harder a spot is to reach, the less it gets picked over. Those are the places worth your time.

 

If you can combine both, low tide on a clear morning after a big swell, you're giving yourself the best possible chance.

 

Stop looking on the sand

 

 

This is the thing that changes everything once you know it. Most people scan the open sandy beach and find nothing. Sea glass doesn't live there. It gets swept in and washed straight back out again before you'd ever spot it.

 

You want the pebbly, shelly areas. The rougher patches where rocks, shells and small stones all cluster together. Those natural pockets trap things and hold onto them. Sea glass is heavier than it looks and once it settles into a gap between pebbles or lodges against a rock, it tends to stay put.

 

The real sweet spot is where the sand starts to give way to rocks, that transition zone where the beach texture changes. Work slowly along that line rather than out on the open flat sand and you'll find far more.

 

The less accessible the spot the better too. Anywhere that requires a bit of a scramble, or that most people walk straight past, is almost always more productive simply because it's rarely searched.

 

Train your eye, not just your feet

 

 

Sea glass hides in plain sight. It sits there amongst hundreds of pebbles that look almost identical until the light catches it differently. Learning to spot that difference is a skill and it does take a little time.

 

The key is the frosted surface. Sea glass has a soft, matte quality that's completely different to how a wet stone looks. When sunlight hits it at a low angle, particularly that early morning or late afternoon golden light, it almost glows. That subtle difference is your signal.

 

Walk slowly. Don't stare hard at the ground. Let your eyes soften and scan rather than focus too tightly. You're waiting for something to look slightly different, slightly brighter, slightly wrong in the best possible way. Once you've found your first piece you'll understand exactly what I mean, and after that your eyes just start to adjust naturally.

 

Sunny days are genuinely better for this. Overcast light flattens everything out and takes away that frosted glow that gives sea glass away. A clear morning at low tide after a storm is the dream combination for a reason.

 

What you might find

 

 

Green and brown are the most common on Cornish beaches, followed by white and frosted clear. Blue is rarer and always exciting. Purple, red and orange are rare enough that finding one genuinely feels like a gift.

 

 

If you want the full breakdown of what each colour means and where it originally came from, I covered all of that in my sea glass colours guide here.

 

Found something special? I can turn it into jewellery.

 

 

This is one of my favourite things to do. If you find a piece of sea glass on a walk, on holiday, on a morning out, at a beach that means something to you, bring it to me and I'll set it into a ring, necklace or pair of earrings, handcrafted in recycled sterling silver, 24ct gold vermeil or solid 9ct gold here in Cornwall.

 

Because no two pieces of sea glass are ever the same, whatever I make for you will be completely one of a kind.
