Thank you all for your kind replies and information, this is just what I needed.

Nisheda, very interesting analysis of the Suleimani name! That is what I was afraid of regarding the name, that it has been bastardized for market conditions so now there is no value in the name. Do you think the second agate necklace might be Chinese in origin rather than Scottish? The second necklace has a lot of druzy-like banding and much thinner and more numerous bands.

I do think these are Victorian. The estate that I got them from had a large amount of old Victorian mourning jewelry, I picked up some nice Whitby jet beads as well. I am showing some of the jet in the photo attached.

In this collection were also some large rock crystal beads and a carved hardstone necklace of what I think might be very nice dark green jade and either red jade or carnelian with faceted rock crystal spacer beads all set in sterling.

Nothing in what was being offered appeared to me to be younger than the 1930s or 40s.

I'll do a separate post on an interesting necklace from this collection that I think might actually be Whitby jet with Venetian glass applied to it! I look forward to hearing opinions on that, too!

Thanks again for all your feedback, I appreciate it very much.
