Hi. I just won an auction of some beads that I know nothing about & would love to hear your expert opinions if possible. These were sold as Ancient Chinese, from the Ordos Culture. They were described as approximately 2500 years old, & about 1.5 inches long x 1 in wide, & perhaps originally made as dice. 3 of them are made from bone & the 4th from stone, as you will see from the photos (which hopefully I attached correctly!). Although it's not a culture or history I know anything about or have collected from before, I was just really attracted to them, & would love to know if anyone knows anything of these or agreed/disagreed with the seller. Thanks so much! Lynne
