This bar necklace from Etsy seller Poise Jewellers gives you the option to engrave it with a name, location, or pretty much whatever fits on the rectangular bar.
It’s a cool gift that can be purchased inexpensively and easily personalized; great for wedding gifts, as the seller suggests. These are made of 18k electroplated stainless steel, so they are hypoallergenic and won’t turn black or green. The bars measure 6×36 mm and the chains are adjustable between 16″-18″.
This sells for US$20.08 and ships from Canada (Toronto).
