I only like classic modern, I wonder if since antique looks are so in fashion just now, if they won't become dated anyway. I would think the old real antique rings in excellent condition would be what collectors want. I have read to keep stones in real antique rings they come with rather than reset them and get them checked for safety and only wear on occasion is the best way to treat antique pieces. If I remember, it is the carved rings that hold the most value. I have a little one like this, but I think mine is probably cast and then carved and so doesn't count. I still have some yellow gold and like it again, but they were never over the top pieces to begin with.
