Help identifying jeweler's mark F inside a jewel shaped diamond

[bluescubadivingfool]

My wife has a 14k gold ring with a makers mark we can't identify it is a diamond shaped mark with an F inside. Any help would be appreciated. Thank you

Unfortunately, this mark isn’t included in the Lang’s Antiques data base.

There’s a smattering of questions like yours online, but without definative answers. Check out the responses to the first question here, though.

IMHO, QVC/HSN would be consistent with the 10K ring pictured in that case.

By the way, is that other marking “925”? If so, that would indicate that sterling silver, or a gold plating over a sterling silver base.

Yes! If there is a 925, then it's not solid gold. It would be sterling with gold plating.
