I have a ring with these markings on it. Can you give me an idea of what it is made from. Gold in color. This is a very old ring found in family estate. Is there any info you can give me on it. A Value maybe in just the metals?
Thank you, Tammy

Questions concerning any type of markings or codes on jewelry are outside my field of expertise and are best directed to a jeweler. Because of the stones, a simple density test can not be performed, which would indicate precious metals. There are certain instruments in a jewelry store to test for the presence of gold, silver, and or platinum.
The reddish hue in the metal of the ring as presented by the pictures could indicate the presence of copper (red gold) as an alloy together with precious metals. This, however, is just a hunch without actually examining the ring.

I can answer questions concerning minerals, mineralogy, gems, metals, and anything that has to do with geology. However, I am NOT a jeweler. Questions about values, settings, gem stone cuts and appraisals are best directed to other experts on this site. I can however aide in the identification of unknown mineral materials. As a public service and part as training for new geoscientists, our university department provides FREE mineral identification for individuals. Please contact me for details or go to for details..
