Thanks ladies, they''re a lot of fun to play with and I would never have been able to make such great choices without everything I''ve learned from the wonderful colored stones addicts here!
Here''s the color shift for that tiny (4mm I think, I lost half my caliper) second-hand sapphire. Under incandescents it has this shocking red flash, but I didn''t capture it and now my camera battery has died, the batteries and charger are in a box, and DH, who''s in another state just now, is the only one who knows which box... isn''t moving fun?
