Smokey, I keep looking at that ring, my eye says their is more to it than a 1940 ish 'style'. Now I know Zero about jewelry so I could be totally wrong but the layout of the jewels and pearl are not necessarily eye catching, its more like they represent something due to their placement. Are there openings under the stones to allow light to flow through them from underneath? I'd guess so as there are openings in the side of the ring that would allow light to pass through which would cause the stones to twinkle at certain angles.
Have the stones been tested to see if they are real? Has the Pearl been tested to evaluate if it is natural or man made? Has the metal been tested to confirm the 14K mark?
The pear, l is it glued on or does it have a stem inserted into it? If a stem was used then 'maybe' there may be a hole all the way through the ring, does it show on the inside of the ring (where the finger would go)? If this is indeed a high value ring then I would think a stem was used otherwise the pearl would be the first thing to be knocked off of the ring.
Have you been able to locate the maker via the mark? Have you posted a photo to some sort of Jewelry site to identify the ring style, design purpose, end use [under what conditions would it be worn: cocktail party ring/organization ring(a special group of women)]. For whatever reason my minds eye says it is special, somehow. Interesting, hence all the questions!..............63bkpkr
