F in a diamond shape - Fessenden & Co
by: Anonymous

I have been researching a ring that I have that is 925 sterling silver as well as 10K gold. It has that same mark inside of it that you were asking about. The closest thing that I found, and I did find information regarding it the company is called Fessenden and Co. apparently people have been researching this mark for years! Hopefully will help with your research.

Not a diamond rating
by: Anonymous

I have a small pendant marked 14K followed by the same capital F contained in a cut diamond silhouette. Although the piece contains 16 "diamonds", they are so small that I doubt any maker would have been concerned with indicating their quality. I don't think the F marking has anything to do with them. The pendant does have a very fine 14K chain but the quality of the back of the dependant tells me it's not "the finest". Strangely, under a jeweller's loop, the back shows some very shiny silver areas. Makes me wonder if maybe the mark stands for Filled? Although the front of the pendant looks well made, the diamonds do not appear to be prong set. This, coupled with the lack of a quality finish on the back makes me think that perhaps Gold Filled is the answer.

I am pretty sure this is the answer
by: Alaskan Sky’s

Ok so I did some research after reading all of the other comments and I think I came up with the exact answer to your question. I believe the F inside of the diamond is the grade that the diamond was given for its color, several comments said they believed they looked like lower grade diamonds and the F is located inside of the diamond symbol so this would make complete sense. I can remember owning a piece of jewelry a few years or so ago with a similar if not the same marking and I found it to be the grade of diamond as well. Didn’t check the date on any of this posting so I have no idea how late this answer is but if you hadn’t gotten a legit enough one yet I certainly hope this does your question some justice and puts your mind at ease. Your welcome as well ! Lol

Same mark, silver ring
by: Anonymous

I have a low quality ruby and diamond ring that I bought in Vancouver, BC that has the exact same makers mark. I can't find any info on it either, but the other post about the 'made in Canada' tag is an interesting lead. There is a similar thread that identifies this symbol as Fressen & Co, but I disagree (that symbol is an F in a square-diamond shape, like a playing card diamond). Anyone else have new info?

I believe it was sold on QVC/ HSN
by: Anonymous

I recently purchased a jewelry lot at an estate sale, and a ton of the jewelry was QVC/ HSN. I have a ring from the estate with the same marking, but the stones in mine are amethysts. However, the ring I have still has the original tag around the band- no maker's name, but it does say "made in Canada" on one side of the tag and "9833 size 5" on the other. The tag was computer printed, so it isn't vintage for sure. It came in a generic HSN/QVC black box like most of the other jewelry, which is the reason I would assume it is from there. I'm actually selling the ring and was researching when I came across this thread.

Same but with an OZ following
by: Richard Breland

My ring is old and has a 10k mark in a square section as the band becomes hollow on the inside the closer it gets to the setting. Opposite is another square with a diamond that has an f in the center but following this are the letters OZ. Perhaps it is a way to grade the diamond or cut. I just don't know.

F in a diamond hallmark on my 10k gold ring
by: Anonymous

I am a buyer & seller of jewellery, & also have a ring with this marking in it...I can tell you the stones are not CZ, but look like low quality diamonds to me...They pass the fog test & have phosphorescence under uv light as well. They refract in light like a diamond, with the colours grey & white. I am not a jeweller, but know what CZ looks like...These are not CZ's. The hallmark remains a mystery, but I think it's a reproduction of a Birk's Ring. With a hallmark that closely resembles a Birk's hallmark...

Yes and no.
by: Anonymous

I am still trying to find out who it is, myself...

For the others, things are what they are. If it's stamped 10k, it's 10k. If it's stamped 925, but is gold color... That's called "Gold vermeil". The ring itself is sterling silver (925) as marked, it was just plated in gold. For something to classify as gold vermeil, the purity of the silver being plated by the gold MUST be at LEAST sterling silver (925, 92.5% silver).

I haven't found out who makes this yet, but makers marks (unless hand made without a proper stamp), will be exact (plus or minus some flaws in the stamping process). They won't take the "F" out of a gem symbol and put it into a diamond symbol. Doesn't match, isn't a match.

Rugged Silver Bracelet

by holly
(apple valley ca)

I have a Silver tennis bracelet...I say that cuz its stamped 925 it has 41 I don't know cubic diamonds I guess in it....and I'm curious to know what the Hallmark on it means...above the 925 stamping is diamond shape with a F in the middle...The bracelet is a bit "rugged" so I'm pretty sure its costume.

Reply...

Holly, you mention "Rugged" SILVER Bracelet is stamped 925, which indicates STERLING SIlver Not Silver Plated.

OK, thanks for the photo! The manufacturer of Rugged Silver Bracelet is most likely:

FESSENDEN & Co. (on Sterling Silver, Providence, RI, USA) - ca 1858 - 1922.

The jewelry manufacturering mark (Fessenden & Co.) is an F in a Jewel Diamond.

Best Wishes,
Yvonne

I FOUND THE EXACT SHAPE DIAMOND WITH F
by: Anonymous

EXACT STAMP FOUND
I was also searching for this stamp and finally found the exact shape diamond with the letter F.
Fesseden and Co. and Frothingham and Co. both have diamond stamped with the letter F inside. But they have a different diamond shape.
AFTER WEEKS OF SEARCHING, I found it.. And unfortunately, it is NOT antique..
Go to https://www.langantiques.com/university/mark/richline-group/
and it will show you the mark with the information.

It was tricky finding the exact stamp on this website using the tools provided but without using the tools and just typing in the bar, I FINALLY FOUND IT.

I too have F in a jewel type diamond
by: Anonymous

I purchased a sterling silver ring marked 925 and also outline of a cut diamond which has inside it an F. I assume the stones are fakes as it is sterling not gold but the diamond shape inside the band confuses me as the stones are brilliant and a slight shade of gray or green however the ceenter stone is bright white and with my loupe I see no carbon. The slightly gray or yellowish stones are the baggets arond the center pear shape which is whiter. Any ideas what I have here as most cz rings are marked cz? These are flashy and also shoot colors like my diamond. Could they be whilte sapphire I wonder?

"f" in diamond 925 silver
by: Anonymous

I was wondering if you found out more about the bracelet. Looking at your posts and pictures it seems that I have the same bracelet with the same makers mark (not hallmark. The only difference I can see is mine has 49 diamonds. I'm estimating that they are .20 carats each. (looking at the size and taking a conservative estimation, it could be .25)
Im no expert but I think that would mean it is a 9.8 carat bracelet. (someone correct me if I'm wrong, .20 multiplied by 49 equals 9.8)

I can't seem to find the "f" makers mark anywhere but I seriously doubt it is costume it was a very important piece to my grandma who was serious about her jewelry. Any news would be appreciated. I would like to know if it is something I should pay to get appraised and insured.

F in a Diamond Shape Stamp?

I rediscovered this ring among my jewelry. It looks to be 14k gold, diamond and emerald. No idea how old it is. The stamp says 14k, and there is also a diamond shape with a capital F in the middle. I've been unable to determine to whom this hallmark belongs.

Any assistance would be much appreciated!

F in Diamond shaped mark
by: Allen

I have a sterling ring marked 925 with this F in a diamond jewel shape mark. It has 70 crystals, not diamonds per diamond tester. This mark has nothing to do with "diamond color". It appears to be a maker which appeared in about 2000, perhaps on a shopping network. The mark appears on sterling, 10K and 14K jewelry. It is NOT Fessenberg or any other company with an F in a trapezoid.

Thanks for reaching out Tina, I am so glad you found us!

The "F" inside a diamond shape , as a "jewel diamond" shape and not a diamond rhombus shape, is the hallmark signature of Fessenden & Co..
This is a common corporate makers mark ion antique and vintage sterling silver pieces.
