Featured 14K White Gold Blue Stones Signed - Help with maker please

I have a 14k white gold ring with an unusual configuration of the blue stones. I tested the large center stone and it is not a diamond. I know the 585 is for 14K. There is a shield on the back of the ring that has the letters SB. Can anyone tell me the time period for the ring and identify the maker. I think the center stone is faux sapphire.

 

They might be lab-created sapphires; synthetic sapphires have been made since the 1880s and have been used in jewelry since at least the 20s. With synthetics they could get caliber-cut stones in matching colors in quantities to make factory jewelry. The center stone...no idea. That's not a horribly old ring; if I'm guessing I'd say 1990s or later. Someone else later may know more and might even know the maker. It's too new for me.

 

Synthetic sapphire in the center (and elsewhere) is my assumption too, since it is 14k. It's definitely the Art Deco style but could be revival...the extra swirly basket on the back says newer to me.

 

The blue stones are shield faceted and it looks like the ring shank has been enlarged by at least 2 sizes.

 

nice pics.......nice Bling !!!

 

oops

 

You are too quick for me AJ.

 

Would I be correct to assume that with the 585 instead of 14k, this was probably made somewhere other than the USA? Still curious about the maker.
