Jewelry, Gems, & Minerals/Unidentified Ring

Hi there,

During a renovation, I came across a ring hidden behind some insulation and I'm interested in knowing if it has any significance.  The red stone appears to be synthetic and weighs .8 grams.  The gold is 10k, weighing 1.8 grams.  There is a small stamp beside the "10k" that could be a sword with an "F" between the blade and the hilt.  Any information would be greatly appreciated!


Dear Joel, as with most of the other experts on this site, I do not try and identify manufacturers because unless the mark is readily known or familiar, chasing down that info is like a rabbit chase on the rabbit's path. Soon enough the critter is out of sight.  I would have to go to estate or jewelry auction sites in the hope of finding the same mark as your "could be a sword with an "F" between the blade and the hilt".

What I can tell you is that the stamping is done according to the Federal regulations with makers symbol stamped close to the karat quality mark, meaning the ring is most likely what is stamped, that being 10k gold.  Rings of this style are most often seen in 10k and with simulated gems.  If the stone is in good condition and not abraded, it is likely man made synthetic sapphire, red color for ruby.  This could be from around 1950's.

Hope this helps some.
God Bless and Peace.  Thomas.

Have a question about jewelry repair or working with precious metal jewelry and gemstones? For many years up to December 31, 2010, I was a working professional bench jeweler, involved everyday with setting stones in mountings, designing and making jewelry, repairing and limited custom manufacture. If you work with jewelry as a hobby or as a profession, I might be able to help. I deal with the retail business, not mass production. Ask privately if you wish. See the box for that: It keeps your question between us. Please DO NOT ask MAKER'S MARKS, but metal quality marks are fine to ask. Please DO NOT ask diamond prices. See a gemologist for that.


I have extensive experience in design, service and making of jewelry. I deal mostly with precious metals and gemstones but work with many materials as needed and usable to create an artistic design. My experience also includes freelance photography and photographer of jewelry and similar items for a former employer and individuals. Design of custom items requires reading the desires of the client and being clear on what can be done within that framework...then fulfilling the transition of idea to reality. Effective communications is essential in a working designer/producer and customer relationship.

Education is English/Physics! Started in human resources, to advertising, to, what a road. I have had formal training in jewelry work and many shared experiences with top grade jewelers. We just never know were we will go or be. Follow your best, your dreams, with some discretion! Don't let the work tear up your body along the way as it has mine.
