My first impression of your photo was the same as Jamey's - there's a mix of lighter lemon custard-with-meringue beads that are most likely Baltic amber, and the brownish caramel-colored beads that bear closer examination.

So, for what it's worth, two amber students have the same first impression.

A Polish amber vendor once told me that they save their opaque caramel amber for the Islamic markets, where this variety is favored for prayer bead strands. So, the caramel beads could be baltic amber, but, as Jamey says, there are some excellent imitations out there with this exact same appearance; hence the need for some closer inspection of these beads.
