I am always researching clasps and found your blog very informative, thank you so much! Looking forward to more post! I have a ring that I cannot place the circa it was made. Do have any information on rings. The ring- saw tooth setting, in a collet, red stone-with a R, and the band looks like someone rolled a pattern on it.
