Jewelry, Gems, & Minerals/Hallmark


Good Day Thomas

I need help with a ring that I want to buy.  The hallmarks are as follow:  18K 750 and next to that a diamond inside 2 half circles.  On the other side of the ring S1.61  It's a sapphire & diamond ring.

Kind regards

Dear Yolanda,

The 18k 750 are legally accepted marks for an item of jewelry made of 18k gold(fine close shot,btw).  I am nor sure of the makers mark although it does linger in my memory.  Maker's marks are generally difficult to identify with much outsourced and many makers going in and out of business over the years.  Do you have an age on the ring? If so, I suggest trying internet sellers and look for something similar then for the makers mark.  

Thanks for the question. I have a note about generally not doing maker's marks in instructions for questioner.

Best wishes and peace with blessings.  Thomas. The mark i somehow familiar and I will check a few places.

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.
