Well, it looks like costume jewelry, is that the kind of category you mean? If there are no metal stamps on any of the pieces likely it isn't gold, and the red pieces appear to be man-made (synthetic stone or possibly lucite?)... It looks to be in excellent condition, and a very attractive set.
Thank you. Yes. I agree with your assessment. What I am trying to determine is who made it and what type of costume jewelry it is. I sell on eBay and I like to be able to accurately identify my products to me buyers.
