Gold-Plated Horn Necklace

A solid and high-quality demi-fine piece in a warm, rich gold-plating that has proven very tarnish resistant. Sadly I can't remember much about this piece, and the boutique I bought it from in Pacific Center Mall (Vancouver) is long gone. I remember it's gold-plated, and the stamp reads "TNJ." My best guess (based on the piece's weighty feel and lack of tarnish) is that this is a thickly plated piece with stainless steel as its base metal. Similar to pieces I have from Missoma, Mejuri, Melanie Auld, Wolf Circus, and other Blue Ruby brands. EUC, barely worn. Length is 18 to 20 inches.
