Glass Pendant Green Black White Yellow with Black Cord Chain 10 in

Cord/Chain is smooth and flexible. The Glass pendant is almost 2 inches in length and 1 inch wide. There are some white areas in the pendant (see photos) that I never knew were there. The glass is smooth with no defects so I don't know if the white area was there from the start. A couple of small closed bubbles - no roughness to the glass. I think I never saw it because it cannot be seen when worn. It is a beautiful pendant.
