I don’t sure you get an email from me or not. For some information about the necklace, they come from Burma. It designs by my friend in Thailand. The etched carnelian bead is special four holes. The line patterns like this meet in Burma more than Thailand. The blue glass beads are Indo-Pacific Trade-wind Beads, we meet blue glass beads like this on many archaeology place in Southeast Asia. About age of them, It is difficult to determine the age because the beads like this pattern made for long time in Burma but I believe it should about 800-1,000 years.

Please pardon me for my poor English.
Thank
