Corundum, Ruby and Sapphire were the the first stones to be synthesized. Vernuil, in France managed to mix the elements in the correct amounts and like sand through the hourglass onto a torch that melted the elements in mid air, dripping down to form a boule. (sp?) This occurred in the 1880's. The "flame fusion" boule then had to be split, (to relax the crystal), cut to form, and faceted. I have seen this ring a dozen times. Made in the thirties with a syn. Ruby. Like a class ring, they made perhaps hundreds at a time. In nice condition, as this one is in, it was always easy to sell at a premium. Masons loved that style, and I'm sure they still do!

synth. ruby? i think not by: bluemlein
despite everyone's acceptance of this stone as a synthetic ruby - i think not. let's recall that the first synthetic rubies were small. and the ones that followed are usually synthetic spinel coloured to look like ruby. generally speaking, most synthetic stones (aquamarine and on) are synthetic spinel.

Rothman & Schneider, Inc. by: Angela
Hi Daniel,
I'm pretty sure that your ring was made by Rothman & Schneider, Inc. You can find their company and mark listed on page 205 in the book "American Jewelry Manufacturers" by Dorothy T. Rainwater.
Hope this helps!

Was this solved? by: Anonymous
I also have a ring with R/S within a shield, stamped in a 14K Gold ring (with two diamonds and a blue topaz in the center).
Was this mystery solved? I can post pictures if needed. Thanks!
