...it was also Firemountain Gems I had been thinking of not Ring&Things in regard to the bead in this thread. Included here is a photo of a similar bead they sell.

The color schema is apparently not warring state, especially the green.

Where does the bead come from and when was it made as a repro?

If you check page 160 in the revised and expanded edition of "The History of Beads," you will see that the Chinese did use green glass for beads in the fifth to third century B.C. Of course the bead shown there is not identified as a Warring States bead nor are the others on the page...though I'm sure many of you would refer to at least a few of them as such. Maybe the book has it wrong? This bead was not sold as a Warring States bead anyway. The funny thing is that I was at Beadazzled in Washington DC and Kathleen who is the manager there held the bead in her hand and said it was a "Warring States" bead. It's a very heavy bead and I do know that barium was used in the Chinese glass beads which makes them heavier. Jan Skipper already told me it was a fake from the photo and a woman at the bead museum in Glendale was uncertain about the very neat opening. And, I purchased a smaller version personally from a man in New York. He presented the bead just as the larger one was presented. Regardless, I absolutely love this bead. And, I won't stop asking just because someone here dismisses it as a fake. Does anyone have one similar...I'd love to see it.

The warring state and Han dynasty green glass bead (or green components on these beads) I've seen before are more bluish-green while the one you presented is yellowish green. I've a simple warring state eye bead with green eye below.

A Han dynasty green glass bead for your reference as well.
Regarding the origin of those repro, i know that lots of lampwork beads are imported from southern asia into china and made 'old'. These may be source of part of those repro. i have no idea about the one your presented before though.

I wasn't able to figure out how to include the link...need an education in that regard. I could however download the photos and then put it here. At least four of the beads.

Hi, Beadster,
The bead you posted is called 'dragon ball' by some people in china. It belongs to 'Yue' culture group which derives its glass manufacturing industry from southern asia (indo-pacific region) as well as north china. Many of these 'dragon balls' are composite bead (with a terra cotta core) but still some, though much rarer, has glass core. And yes, i saw yellow green in some of these 'dragon balls', mostly darker, but it's almost for these 'Yue' culture group beads only. They're very different from the one you posted earlier, whose style is more like western asia stratified eye bead. Furthermore a great portion of 'dragon balls' are brick-red or aqua-blue, too.

but I thought you might enjoy these pictures. To be clear, for as far as I can tell, all items on these pictures (from the Beijing Panjiyuan market) are replica's, fakes, articifially aged items.

Your bead piqued my interest and sent me looking for this bead. I have three but this is the greenest. It is a tiny bead, only measuring 4 cm. What struck me about your bead is it appears to have a translucent quality. It is very pretty but the translucence throws me off.

My bead is slightly translucent when held right up to a bright light. It is rather thick and it is heavy.

Found more beads I forgot about. BTW, Jake from Nomad, Matt AKA Beadbox and, hopefully, Rick Rotten are going to put another show on at Jake's shop. This one will be called "The Magic Eye Bead"!!!! Matt has also piqued the interest of the curator of the Fort Collin's museum and we will all contribute to a show there in April called "Baskets and Beads" or vice versa. How cool is that. Hopefully we will chronicle THIS show in photos and post them. Back to these eye beads. I believe them to be ancient-let me know if I am wrong. I want to display the eye beads in Jake's show.
Beadster- what caught my eye is that the fourth bead on the right (pardon my hasty photography) is similar to your eye bead. It appear to have a greyish green core but in fact presents itself as almost black. It might be one of those dark purple beads that mimics a black bead and is quite frankly densely translucent.

I wish that I could be there for that show in April! I really like the smaller bead that appears black at the top with two eyes showing to the left of the red beads. Here is the last eye bead that I acquired, it has a greyish green body. Again, thanks for sharing...I love eye beads! They look ancient to me...but, what do I know.
