I don't have that many tektites.. a couple of pounds I guess....But they do
not look anything like apache tears, snowflake obsidian or regular obsidian
to me.

Wabar pearls may be similar to obsidian in appearance.. but not apache
tears...So I am ignorant of the problem. Apache tears come form the
Superior mine in Arizona. I do not know where else.
