Regarding the Hutton beads, here are some better photos that show their beauty and luminosity. In the case of this necklace, I believe the high price has to do with the how perfectly matched the colours of the beads are, the translucency and their provenance. Glowiness is probably not a requisite for this necklace’s desirability, although I bet it would look glowy if taken out of a dark auction house and into the sunlight.
I want this necklace! Glow or not glow.....LOL.
