Hi folks-

Been a long time since I was here much. However this topic caught my attention and I thought is worthy of the attention of the gemology folks here. And you all probably collectively can address their questions far more intelligently than I.

(I'm going to re-post this to a couple other sub-forums here; I simply want to get the right eyes on the pics- delete if appropriate!!)
