I saw this over the weekend at the Houston Museum of Natural Science. Its called the Westminster Blue Enamel Kokoshnik. Tiaras are pretty and all, but I would rather see swords and armour. However, this really stopped me in my tracks. It is housed in a permanent exhibit called Faberge’: Royal Gifts. The whole exhibit was amazing, but this piece is just crazy to me. Its meant to look like a traditional Russian headdress called a kokoshnik.
This last one you can see the transparency of the blue glass a little better.
