I have purchased numerous blue and green Montana sapphires from Bob
Miller, but don’t know if he carries much white sapphire. FYI, he
also carries Idaho opal. Here’s his contact info:
Bob Miller’s Bedrock
2615 N Fourth St
Coeur d’Alene, ID 83815
P. S. I think we met when I was doing classes at Revere. Hope things
are going well for you.
