Rare Cobalt & Blue Seaham Sea Glass Collection – Genuine English Beach Glass for Jewellery Making & Collectors

A stunning mixed collection of genuine Seaham sea glass featuring beautiful shades of cobalt blue, lavender blue, cornflower blue, aqua, and icy pale blue tones.

Blue sea glass is highly sought after by collectors, but true cobalt pieces are especially treasured due to their rarity and striking colour. This collection includes a wonderful variety of naturally frosted blue tones, creating an eye-catching display that feels both vibrant and coastal.

One standout piece is the soft aqua heart-shaped sea glass, adding extra charm and uniqueness to the collection.

All pieces have been naturally tumbled and frosted by the North Sea over many decades before being carefully handpicked from Seaham Beach in the North East of England, one of the world’s most famous sea glass beaches.
