Here are beads that I was able to buy in pairs—so I could use them in necklaces.

The next photo shows two different reproductions of the typical jatim that feature a simple millefiori spot (or "eye") pattern—usually a white center surrounded by green or blue. In this instance, the central more-authentic-looking bead is from Jember; while the smaller flanking beads (that are less convincing) are from Jombang.

JDA.
