Got this message from the Tiara people:
This is a refund for the Tiara Silver Emerald, item number TA_202_Emerald. I appologize that this tiara is out of stock and the manufacturer has told me it will be discontinued.
So sad about that!
I have gone ahead and bought a different one. Not my first choice, but a very close second.
Here's a link to the seller so you can view how it can be worn (while the link is available, it is eBay after all!)
