Help with ID - Deco Ring "S" Mark

Hi all, first-time poster here, but I hope to have some fun things to share with you as time goes on.

I have a beautiful platinum Art Deco ring with a maker's mark that I can't ID and thought someone on here might recognize. It's a stylized "S" with dots on either side. I'll attach a close-up of the mark as well as some glamour shots of the whole ring .

Based on the metal, design, and cut of the diamonds I am placing it in the 1920s, but I am pretty new at this so if someone has a better idea of time period please let me know!

Something looks off for a ring made in the 20's.The photos are too bright and the reflective background does not help.

 

did Suzuki make rings...??

& while I don't know the make up of a platinum ring....it may be 10% Iridium ...like this,,,,,



Or is that Iridium PLATE !!????

 

Looks like the real deal....

 

It is a "real" ring,but the above dating is questionable.

 

Yes, the center diamond looks to be a modern cut.

 

The stone actually looks like an old European cut diamond.

 

This may be the mark of N.M. Shepard & Co. Inc. of NYC. They were a quality jeweler at the time.

 

I thought the same company, Calico; however, the only mark I could find for them has "N", "M" and "co" worked into the curves of the "S." There is a good possibility they had other marks that I haven't had any luck finding.

Yup Susan, that's why I said 'may be'. It will be hard to nail down unless a similar mark can be found in an old ad or book. Beautiful ring.

 

I still think it's Suizuki.................
