It looks as though you got a wonderful Christmas present and you'll have a great time investigating each and every one of them - because that is what you will have to do.

Jatims comes from Java Timor - East java - where they were made in ancient times (C5-7) and again the past twenty years or so.

It really is very difficult - even impossible some of the time - to separate the authentic from the fake on the basis of photographs. I even find it hard sometimes with a fake in one hand and the real thing in the other. But from what I can see here I think there's a good chance that at least several of your green and yellow beads and some too of the red/blue/yellow ones are genuine.

I'm pretty certain that the pelangi (rainbow) bead is a fake made in the early to mid 90s, not because of its size, as Flor suggests, which is actually not abnormal, but because of the colours and composition (it's almost certainly not all glass). I'll attach a pic of a genuine, well-provenanced one (5cm), for comparison.

Also, I'm very doubtful of the bird/sun beads. I think the white motifs might very probably have been added later to what may be an older monochrome bead.

But really these are all worth spending a lot of time with. Read Jamey Allen's book Magical Ancient Beads and also check out Jatims in the archive here, which will give you a lot of additional information. And then try sorting them out yourself; soon, I bet, you'll be separating the real treasures from the later copies. And on another level it doesn't matter too much anyway; even the fakes are beautiful beads in their own right.

Cheers,

Will
