I recalled reading of a cat's eye brooch and have found it in Menkes.
"Enormous cat's eye weighing 313¼ carats set in diamonds taken in conquest from King of Kandy and presented to Queen Victoria."
--Previous Message-- : : Thank you for the explanation Lennick. I : have never heard of the cat's eye effect. : : : --Previous Message-- : Joye posted a thread earlier, I posted a pic : of Cat's Eye Chrysoberyl further down the : thread. Here : : http://members2.boardhost.com/royal-jewels/msg/1415164550.html : The only argument I have for it is the : cat's eye effect that can clearly be seen on : Camilla's bracelet. It's a rare effect that : happens on so few stones. : : Call it a gut feeling. I've been a jeweller : for 25 years, working with gems every day : and as soon as I saw Camilla's bracelet I : thought Chrysoberyl. It's so distinctive : and hard to mistake. : : Of course I could be wrong, and my comments : on the Alexandra bracelet were just : guesswork. After all, how can we really be : sure? : : --Previous Message-- : : Lennick - do you mean a chrysoberyl in that : bracelet? Unfortunately that pic has been : colourised. : : Edit: I cannot identify the gem but am now : convinced that it is not a pearl in : Camilla's bracelet. : : Edit 2: a pic for comparisons : : : : : : : : : : : --Previous Message-- : Excellent find Joye. Looks like the same : piece to me.
