It was a quite the scene in Tokyo on Monday when people linked up to get free diamonds. French jeweler Mauboussin gave away .1 carat diamonds in order to drum up attention for their brand. People came from surrounding cities to line up for the promotion. The tiny diamonds are worth about $50 each. The Maboussin flagship Japan store opened in the Ginza shopping area earlier this year but found that they weren't getting a lot of foot traffic because the store's name was basically unknown. Maboussin will make any free diamond into a ring or pendant but that will cost around $500.
