a personal calling card, to the nth degree

A few years ago I wrote of the importance, style, and class of a proper calling card.  The highlights of my vantage were that calling cards were the perfect way to leave an impression, to stay in touch, and to advance your stature. 

Now, a British firm  is taking the idea to a whole new stratosphere of luxury and opulence.  For nearly US$1500 per card, Black Astrum incorporates precious stones and metals into the most luxurious business/calling card imaginable.  Gone are the days when traditional business cards are misplaced - presenting a diamond encrusted card solidifies your wealth, power, and place in the luxury society.  Or maybe just highlights your ostentatious, over-the-top, persona.

What do you think?  Are these cards tacky or terrific?
