People ask me often how to tell if sea glass is authentic or fake. There are ways and this video just gives you a quick lesson on how to tell. Many, many people (Including myself) have tried to similiate surf tumbled sea glass but it can't be done. Unless I have never seen a way! I have tumbled glass in my tumbler with many different kinds of abrasvies inclusind sand! And I have waited weeks for it to work but to no avail.
