20mm Mother of Pearl Button
Made of natural shell and simply carved from sea shell, this charming button has two sides so opposite from each other you almost have two buttons in one. On one side is smooth blue-white pearl and the other is brown and mottled like the ocean floor. And because they are made of organic material, each button is different, so expect variations. Shank hole measures almost 3mm. Button diameter is about the size of a quarter.
