I have this strand since about 10 years. A long strand that I guess chalcedony with beads from 12 to 18m. There are 2 very blue beads that looks so different from others. Can the chalcedony be naturally in this strong blue color?
My 2nd question is: with the length of 130cm of the string, maybe Fred could tell me if this can be a broken chinese court necklace? But the beads are graduated so not sure, just my later thought after looking at them for years...
