Checking eBay for only the first 3 pages of over 17,000 listings under search "jasper beads" I didn't see any exactly like yours, Jamey. But there are a host of beautifully colored and patterned beads out there titled as many kinds of jasper. I can't help but to guess that these are mostly synthetic concoctions perhaps using recon genuine material, resins, dyes......Here's a pretty one titled "Sea Sediment Jasper". Most all beads from sellers in China.

Russ hopefully can provide some info. Below is the R & T gemstone index, a very helpful reference. But I don't notice Jamey's example or the "Sea Sediment" there yet.

Wish Si Frazier participated here too!
