The problem with the theory that their necklaces are Dust necklaces is that they're not even remotely the same color as any color of Dust in existence.

Dust comes in bright vibrant colors of red, blue, yellow, green, orange, white, cyan, and purple. Those are the colors we've seen so far. Though, in order to spot purple, you'd have to pay ultra close attention. We've only seen purple in Weiss' possession so far, so either it's incredibly rare (because it's hard to make) and/or expensive, or it's her own specially-made Dust.

I say make/made because the four naturally-occurring colors are red, blue, yellow, and green. All others are made by mixing two or more of those four either naturally or artificially.
