Funny, as i was looking at the gem tang and conspic angel, i was wondering the same thing.
I recall two more gems recently. I'm guessing they sold, too.
On a somewhat related note,
The aussie strawberry shortcake frags all sold within the first few minutes. They must have had 15-20 or more frags. Then the DFS strawberry shortcakes were sold right after those. Gone as well. Now, it looks like the DFS red dragons went in less than a couple minutes.
What a marketing plan they have there. The whole idea of releasing limited quantities and competing to be the first to buy fish or frags seems to move them more quickly. Good on them.
