Beginning more than 10 years ago, and I'm not sure for how long, well known bead seller Kamol, from the Pacific Northwest, had Luk Mik style beads made. I've seen them sell from 3.00 - 30.00. At the same time he also had lovely smaller flat oval agate beads made, in graduated strands, and I've also seen large ones sold as singles...I don't know if he's still having them made or not. Sorry, I don't know for sure where they were made, but Thailand or India are possibilities. They are nicely done.
the quality of these beads are superb and have never seen such good quality other new dzi beads. the owner told me that he purchased beads seven years ago in India but he was sure that these came from Tibet, but I don't think they were originated from Tibet.
as you see, there are some old patna on these beads so i am wondering whether they have made in Scotland during the victorian period ?
I am just told by an archaeologist who worked on ancients beads that these beads beads looks much older than 19th century. Looks like, I have bought some old Luk Mik s(Goat's Eye).
I have been educating people about these sorts of beads since they first appeared in the international marketplace.
Joycy has mention Kamol, who sells recent/new agate beads from India. I would say it is a mistake that he "has these made." They just a products, made to resemble ancient beads (that were also made in India). The impetus for making these products was instigated by Mark Kenoyer in the late 1980s.
There are both Indian and Chinese versions of ancient banded agate beads. Your beads look Chinese to me—and they have been made for the Tibetan market—and are routinely offered for sale as "ancient" beads, for high prices. The Chinese began selling these beads in 1992.
I highly recommend reading my exposition on Tibetan zi beads, published by Arts of Asia in 2002. It is the most encompassing exposition of zi since 1982. See the link posted here.
I show my collections of these beads at my Facebook Group, Beadman - My Stuff.
