Thank you, Stefany, for this lovely image of you and Tom. It looks like all had a great time. Stefany is wearing some of the bead types being discussed here. Here is her caption:

"This shows myself and my son Tom at the opening party of the new Longchamps flagship store he designed in Soho, New York, and its just noticeable that I'm wearing among others one of my personal all-time favourite necklaces rethreaded for the elegant occasion which is composed of a series of these beads, both old and recent, real agate and glass lookalikes. One extra observation is that some of the layered agates seem to be of glued layers as a few have separated.
The other necklaces are shell discs from one of the Himalayan goods dealers from Bead Expo a few years back, and a strand of small shell Heishi-type, and a Naga strand of old red glass."
