I'm truly clueless as to the actual size, color, clarity, or cut. I'm thinking it's just about round, so maybe an OEC and somewhere in the 1+ ct range, but with the setting it's in, it might be smaller. Of course, should it come down to me eventually, it'll be off on a trip to visit David, and make sure all is safe and tidy, and maybe get some educated guesses about her.
Dad was born in '11 with 2 older sisters, so the ring, itself, dates back to the very early 1900's or very late 1800's. Guessing again, the workmanship is probably Mexican, as most of the family diamonds came through there, where one old Gordon great-great was a jeweller in Mexico City. I know my Mom's diamond, which came from one of Dad's aunties, was also from that collection. My sis has some old photos of what looks like a parure of diamonds worn by one of the great aunts. Family tales have it that the girls used to go to NYC once a year to refresh their wardrobes. Quite an adverturous train trip back then, coming from south central Texas, as they did. Unfortunately, there is no history as to what happened to the diamonds in the course of the last 100 years or so.

And Annie, it's a dirty job, but SOMEBODY's got to do it. Might as well be those of us who care, right?

We're none of us particularly AR or OCD about things, now are we?
