I just found this question and I know it is very old but I do have an answer.  I just purchased a very expensive ring from a local indepedent, very reliable jeweler and my ring is stamped LibCo2.  I am also a jeweler I did not recognize the hallmark so I called the jeweler that I purchase the ring from and she told me the hall is for the Libman Company.  Here is the information for the "Libman Company".

The Libman Company Inc. 1515 N Warson. St Louis, MO, USA 63132-1108. Tel: 416-661-2661. Toll Free: 800-268-1995

Libman Co in CANADA supplies the Libco rings in the USA. They ARE fine jewlery, and the number  has to do with the quality of the stones.

mine says Libco 4 14K

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.
