Antique Art Deco 14K Gold .10CT Diamond Pendant

Dating to the early 1920s, may I offer this Art Deco 14K White Gold (hallmarked within the bale - hard to photograph) pendant. Set with a single 3mm (10 point) faceted round diamond, color is G-H and clarity is SI1-2. From top of the bale to bottom measures 3/4" long; width is 7/16". Weight is .8 grams. Condition is perfect and yes, it is entirely possible the piece was once a stick pin top however, since I found the piece as you see it, I am only guessing. All that's needed now is the right chain - mine is for display purposes only.
