Luxury goods company Black Astrum's custom-designed business cards (roughly $1,500 per card) are made from hefty Swiss metal and dotted with actual diamonds (a pack of 30 cards includes 30 carats). "We've had several inquiries from American celebrities and international businessmen," says Black Astrum's Sufian Khawaja; "however, our cards are offered by invitation only, reflecting our desire to serve only the most premier individuals."
