I went to an FTD site and looked up orchids and sure enough I found this:
Vera Wang™ Pink Sapphire Orchid Bouquet
It looks like you received the Vera Wang Pink Saphire Orchid Bouquet?
Your orchids are Mokara, which is a hybrid member of the Vanda Alliance. Many Mokara are grown in Singapore for the cut-flower trade and exported around the world. They will probably last a few weeks for you if you keep them in fresh water.
They really are beautiful!
