Are these freshwater Biwa or Baroque pearls?

[UniquelySimple]

I bought these at a second hand thrift store. Could someone help me identify these type of pearls? I've tried investigating online, but have found differing answers. The finding is 925 silver.

They are stick pearls. They have a strip nucleus. Biwa pearls (pearls from the Japanese lake Biwa) used to be similar in shape but have largely disappeared due to pollution. But the name stuck and got applied to stick pearls from anywhere

That is very helpful! Thank you very much!

Seeing Lake Biwa in person was very disappointing !
