I ORDERED THE FIRST ONE AND THE STONE WAS UGLY; IT HAD NO RAINBOW. IT WAS ALL MILKY OPAGUE.  SO I THOUGHT I JUST GOT A BAD ONE AND I ORDERED ANOTHER ONE, AND WHEN IT ARRIVED IT WAS JUST AS BAD AS THE FIRST, SO I SENT THEM BOTH BACK. NOT WORTH THE MONEY. MAYBE THEY CAN'T GET A DECENT STONE IN THAT SIZE.
