Hunting for sea glass on Seaham seashore is more like collecting precious gems. With every tide, the beaches here are speckled with coloured, pebble-like glass pieces that have been moulded by the North Sea for over 100 years.
It is a bright, balmy morning in Seaham, a lively town on the Durham Heritage Coast which lies in the heart of North East England. My fellow travellers and I are on the way to Seaham Hall Beach (also known as the North Beach or Glass Beach) which is the richest source of sea glass in Britain. We are told that with every new tide, the sandy shores of Seaham are sprinkled with a fresh supply of gorgeous, frosted sea glass that has been tumbled and smoothened by the North Sea for decades. Perhaps, that’s what makes Seaham such a treasure trove for sea glass collectors today. Whether we are required to sift through the sand, dig in using a stick or a spade, or simply walk along the shore, stooping and keeping our eyes peeled for something colourful and shiny, we are ready to play beachcombers seeking precious keepsakes.
Seaglass Hunting at Seaham
A Trash-To-Treasure Story

Sea glass is mainly man-made glass which is discarded into the sea and shaped by the currents over several years before returning to the shore. So, what’s the story behind Seaham’s sea glass? During the Victorian and Edwardian eras, particularly from 1850 to 1921, there were many glass factories up and down the northeastern coast of the UK. There were six factories in Seaham itself, including Londonderry Bottleworks which was one of the biggest. These glass workshops produced up to 20,000 hand-blown bottles every single day. Every week, a ship loaded with these bottles left Seaham harbour to deliver its cargo to warehouses in Rotherhithe – a district of south-east London – returning via Antwerp with silver sand which was again used as a raw material to make more glass bottles. However, the story of sea glass began when a massive amount of waste glass from these factories was simply dumped over the cliff into the sea. A lot more scrap was discarded when the glass factories shut operations in Seaham during the 1921 coal strike; mainly due to the introduction of machine-made bottles which made handmade bottles obsolete. Well, humans didn’t consider recycling then but nature did. The sea beautifully worked its magic trick on waste glass pieces, rolling off and smoothening all the sharp edges and giving them a gemstone-like appearance.

Since the factories produced everything from fizzy drink bottles and vases to dainty, hand-blown perfume flasks, medicine bottles and bottle stoppers, there is sea glass in varied shapes, sizes and colours. No two pebbles are the same. The Seaham Hall beach is strewn with common amber, blue, white, and green pebbles, rarer types like red, pink, aquamarine, yellow glass, milk glass, dual-toned glass and multicoloured pieces and black glass which is said to be the oldest in the world. The different shades of glass were determined by the chemicals used in the process of glass making as well as the melting time and temperature.
Gemstone Picking Escapade

We spent hours patiently and calmly hunting for sea glass on Seaham Hall Beach, listening to the sound of the waves and feeling the breeze. We realised it is quite a therapeutic experience! No wonder people from different parts of the UK and the world come to this beach for nature’s special, sought-after gifts. In fact, some hunters even come with torches at night.

Local sea glass collectors are finding creative ways to put these beach jewels to use. With a pocketful of gifts from the sea, we arrive at Seaham Waves, a jewellery-making studio and a family business owned by Gavin Hardy. They hand-collect sea glass from the beaches along the northeast of England’s coastline and use it with sterling silver to craft dainty, elegant bijouterie. “As children, we always went to the beaches for recreation instead of the parks. We used to throw sea glass as far into the sea as we could. Of course, we don’t do that today! Instead, we collect them, drill them and set them in silver to form delicate necklaces, bracelets, earrings, finger rings and more,” says Hardy who is a self-taught jewellery designer with clients all over the world. While one can choose from his vast collection of sea glass ranging from plains to rare reds and rainbows, each of us decide to have him create meaningful pendants from the sea glass we picked from the beach. It definitely makes for a souvenir with meaningful memories attached to it.

Unlike many beaches around the world, there are no rules or restrictions regarding sea glass hunting at Seaham. However, it’s best to be thoughtful and pick just a few as a memento from your time here. This will enable others to experience and cherish the incredible phenomenon.

Walk the Durham Coastal Path

There are little villages and scenic beaches on the way if you wish to make a stop or a detour. If you don’t want a tedious, long walk, you can also do a shorter roughly two-kilometre path (about a 90-minute walk) from Noses Point, Seaham to Hawthorn Dene Reserve.
