Late last year KOH Cosmetics unveiled their Diamond Nail File.  Already well-known for their luxury hand and nail products, KOH raised the bar with the nail file that features more than 28 karats of diamonds set in an 18-karat white gold grip - valued at 39,950 Euros (nearly $54,000).  But this product isn't all about the bling.  In my opinion, the greatest feature of this luxury item is the allocation of the profits it gains.  KOH has pledged to donate all proceeds from the sale of the file to Orange Babies, a charity that provides support to pregnant women in Africa who are infected with HIV.  The Diamond Nail File is the first in a planned line of diamond-studded products KOH will introduce over the next few years.  Sales of all products in the line will benefit Orange Babies.
