Art Deco ? Shaped Diamond & pearl pendant

This Art Deco question mark pendant was a stick pin that I converted into a pendant. It’s all original the bail is the original stick pin and is 14k yellow gold. The question mark is 14k white gold. All stones are original to the piece. I’m really tempted to keep this one, it’s extraordinarily nice. The scalloping around the diamonds, the quality of the diamonds, the millgrain is nice and crisp. One of a kind piece here.
