Ah that's interesting info. Thanks for sharing. When I 1st came to know about the Rainbow I was set on PG but when I found out WG n PG had different sets of gemstones and compared these on Mohs scale in terms of gemstones hardness, I decided to go for the WG instead.I can't remember off the top of my head the exact details, but apparently when you special order the rainbow, now it is a slightly different combination of stones. I cannot recall if they are all sapphires now, or if there is still another stone in the mix. I believe they tried to eliminate the softer stones that were previously in the rainbow. I asked for a special order of another bracelet with purple amethyst, which used to be in the rainbow, and it was declined, however various colors of sapphires were approved.
So my hunt continues....
