Looking for any quality obsidian rough — Apache Tear, rainbow, snowflake, mahogany

Building my obsidian reference collection and looking to acquire quality specimens from across the US Southwest. Have been using Apache Tears from Arizona in my lapidary work but want to expand into display-quality material. Specifically looking for: - Large Apache Tear nodules (5cm+), translucent quality - Rainbow obsidian slabs from Glass Mountain or Glass Buttes, Oregon - Snowflake obsidian rough — will buy in bulk - Mahogany obsidian from any Southwest US locality Not interested in Mexican material for this project. US or Canadian provenance only. Fair buyer, pay promptly via PayPal or Venmo. Can do partial trades for Arizona turquoise rough if you are interested in that.
