Question about Granat wedding band by: Melissa Beth
My grandmother just died, and I now have the wedding band that she wore up until her last moment. Any additional information I could find about it would be much appreciated.
It is a small band with four small diamonds arranged in a line. The band has a curve to it, rather than being straight across the finger. I believe it was purchased sometime near 1960 from Granat Brothers. It may have been part of an engagement and wedding band set.
The markings inside the the ring were tiny and worn down. I believe they said "GRANAT MFG CO" on one side and "18K FSun JS 20 XII 59" on the other side.

G.M.Co stamp by: Denise
Hi, I have just subscribed to your page :) I am new to purchasing vintage rings and have a love for the pieces of the 1920s and 1930s. Today, I came across a piece with stamp of: G.M.Co 900 platinum 100 iridium It's a platinum ring with 8 estimated 10 pt. horizontally placed diamonds encircled by 20 smaller diamonds.
I'm trying to find information on the stamp to learn more about the piece but am finding limited information. The posts here have given the most information but still not enough for me to know much about this piece.
Any input most appreciated! Thank you!

Patent Pending Clarification by: Anonymous
Hi and thank you very much for the patent number elucidation! I did a qick google and did find a ring with same pat. With three 'sets of two' tiny diamonds set in white gold band and separated by two tiny raised, rose gold squares. Platinum would have been in the height of fashion at the time the ring was presented. Thanks again.
Warm Regards, Yvonne

Ring inscription Pat 1792422 by: Anonymous
Hi Yvonne,
The inscription Pat. 1792422 has nothing to do with Gorham. It is a Patent number issued by the US patent office in 1931. The patent was issued to J Granat and it was for a type of ring that was designed so that the stones mounted into the ring did not extend below the sides of the wearer's finger. Because these rings were bridal sets they were to be worn continuously and the wear, if the stones were set below the upper edge of the fingers, would eventually cause the stones to fall out. My father gave my mother one made of platinum in 1939 with the same inscription as the one you have. Google "ring Pat 1792422" and you will find more information.

GMco historicism by: Fortuna
Gorham originally manufactured beads, earrings, gold chains and other small wares. The business that would grow to be the Gorham Manufacturing Company was founded by Jabez in 1831. It was at this point that Gorham, in partnership with Henry L. Webster, began the manufacture of silver spoons under the name Gorham and Webster at 12 Steeple Street in Providence. All silversmithing at this time was done by hand, and while the company continued its slow growth, production volumes were always small. With steady investment and the implementation of mechanization Gorham’s sales continued to grow.

Re: G.M.Co gold ring by: nanajean
I, too, have just come upon a ring in my mother's jewelry. She is living but has no recollection of where the ring came from or to whom it belonged. It has G.M.Co 14K-18K stamped inside and on the opposite inside it is marked Pat. 1792422. It's made of 2 grades of gold and set daintily with 3 diamonds. Looked up the patent no. and found it was issued in 1931. Another mystery.

I have a Gorham ring like this too by: AG
Hello, I have a gorgeous, dainty ring that looks much like the one pictured here. The .56ct diamond is round and brilliant. It was appraised in 05 just under $4k. It was my great-grandmothers engagement ring, but we dont know if she rec'd it as an heirloom from her mother or perhaps mother in law.
I do know that the founders of Gorham Manufacturing had a beautiful building on Fifth Avenue in Manhattan, which is where my relatives lived. However, I cannot find any examples of the early peices that were made. If I get a response to this post, I will post a pic :-)

Probably Not Gorham MFG by: Anonymous
Hi Yvonne
you are absolutely correct, Gorham are associated with Sterling Silver - and the mark will have a decimal point between the G & M. There are a few presentation pieces made in gold however, apparently in the early Gorham Manufacturing UK days they manufactured gold chains.
Yvonne, back to your Mom's mystery ring - not sure, could be a pseudo- mark, or possibly a mark that's not registered. Or a registered mark we haven't yet encountered. A photo of the mark would help a lot - you can upload a photo in a follow-up submission (unfortunately there is a long waiting list so be prepared to wait it out) and if homo luminous has any info on this mark to help us unravel the origins of this mystery ring, maybe you have a piece of jewelry with the same mark, GMco (no decimal point) please let us know!
Yvonne - thanks for the comment on the ring's hallmark. I looked into Gorham Mfg in the UK and it seemed they did only silver items. Do you know for sure if they also did gold rings?

Mom's Mystery Ring by: Anonymous
Hi Yvonne thank you for writing in with the following hallmark question:
"Mom passed away 2 years ago. My sisters and I just recently had the strength to go through Mom's cedar chest. In it, we found what appeared to be a 1940's style engagement ring that none of us knew anything about. We are calling it Mom's Mystery Ring. 14k yellow gold, white gold around the diamonds, largest is 1/2 karat. The stamp inside is G M Co. What does this mean?"
Yvonne, what a lovely diamond ring, and what a surprise.
The mark G.M. Co was used by
GORHAM MFG Co. (on items made at their factory in Birmingham, UK) - ca early 20thC
