Walking along Ussuri Bay in Russia, you'd come across many colourful 'pebbles' that sparkle in the sun.
You wouldn't expect this beach to be a dumping ground for glass bottles and porcelain waste from a nearby factory during the Soviet era (1922-91).
Over the years, the waves have washed over these discarded items, dulled their sharp edges, and transformed them into beautiful 'pebbles' that line the shore.
Once a dangerous place for travellers, the 67km-long Ussuri Bay is now a tourist attraction.
Instead of picking up seashells as souvenirs, visitors are sharing photos of their unusual finds - a lovely mixture of glass, porcelain, and tile pieces.
According to The Siberian Times, the best time of the year to catch the beach's beauty is in winter, where the colours of the glass contrast vividly against a blanket of snow.
For those who prefer not to brave the cold, you can see these 'pebbles' gleaming against Ussuri Bay's black volcanic sand in the summer.
And as demonstrated by travellers on Instagram, you'd better not kick off your shoes here.
