I fully agree with you about capturing them on film, i wouldn't think they were the same vases in some pictures i've taken, it's all about catching the right light which is beyond my abilities i'm afraid.
My wife is keen for me to sell these on and turn a nice profit, but i love them too much right now. When i bought them i had no idea what they were, just liked the look of them and took a bit of a punt.
