Price listed is for one ounce of octagon settings. I would say 75 % of these are brass settings. A few are plated but the majority of them are raw brass and made in the US. These are all Octagon settings with most of them being for point back stones and a smaller portion of them will be for flat back stones. There could be a few cast settings mixed in. Most will have very little patina. But, there could be a few that have a heavy patina. The majority of these are 10mm and larger The one ounce sample pulled contained 32 pieces. The smallest setting in that mix was about an 8/6 and the largest one was 27/18. These were mostly in the middle range. We can not guarantee the number only the weight. There could be an occasional different shaped setting mixed in.
