I thought I have written all there is to say about sea glass, but here is something more to watch for. That is, sea glass or just glass that has been painted red, yellow, orange, whatever. This is not genuine, unaltered, natural sea glass. True sea glass artists would never paint it to obtain colors. It is just another variation of man made or artistic look alikes. All Lucky Sea Glass colors are genuine, unaltered by me, created just by the surf!
