First off my opinion of JTV is really doesn't matter. They are a top jewelry and loose gem stone dealer period. They educate their consumer verses just selling stuff. The show host are personable, in fact through facebook one helped arrange for me to buy a museum quality tanzanite. Yes they have costume jewelry lines like titanic, which by the way is interesting if you watch. They teach you history through the pieces. But they deal in high in expensive, legit product. One of their co founders was named the third all time gemologist this year. He was a down home guy who wanted to share luxury with regular people. Before judging them please do your research.
