I don’t watch the show 2 Broke Girls and had no idea a lead character had worn a necklace that had sparked a frenzy to find it until a friend sent me a link to this Etsy item.
Made by Getyourjewlzon, it is a custom order and there is also a matching bracelet and earrings available. The necklace sells for USD $49, a very reasonable way to emulate some small screen style and amp up your pearl quotient at the same time.

It was such a frenzy because surprisingly you like many others did not offer the transparency in noting that this was a one of a kind vintage piece.
Thanks for yr comment The Etsy shop owner also says he made the one worn and several backups. That’s all I noted in my post so as for transparentI think I was. Wasn’t aware it was copied from a vintage piece but there is so much of that in all jewellery. Particularly vintage. I’ve shown some examples using the label compare and contrast if you’re interested. Try also Boucher.
Did you know the two broke girls are in Ellen today.
Was one of them wearing this necklace 😉
Seriously though .l.. have never seen the show and don’t know anything about it. The Internet has ruined my TV watching. Not to mention my attention span. Sad but true.
