I was looking up ancient glass information and came across these on www.ancientbead.com. They're such a beautiful blue color! The caption says,"Wonderful blue colored glassbeads with stripes.
The square beads: Greater India - probably Maurian Period 300 B.C. - 100 A.D."

Are they affordable beads? Has anyone ever seen any for sale? If not, does anyone have pictures of more examples?

In a blue phase! :^D
