Yes, sea glass can be found on the beaches. In fact, sea glass or beach glass comes directly from the ocean onto our beaches worldwide. It is glass that has been deposited into the seas and has spent its time being smoothed by the motion of the waves and the sand. The best time to look or sea glass is right after high tide and follow the tide out to see what treasures have been left behind. I find rocky beaches the best and it catches these gems in between the stones.
Polish beaches are sandy, yes, but they are not on the Black Sea. It's Baltic Sea.

You can find Cancun and the Mayan Riviera: beaches of white sand in front of a beautiful, emerald sea.
If by seaglass you mean bits of glass tumbled by the sea's wave action, and deposited on the beach, then you can look on the beaches. Otherwise, you can search for a jeweler or a boutique outlet that sells jewelery made with seaglass bits.
