French (and other foreign languages) are always popular when you want your design to look a little outre. Unless, of course, you are French, in which case it all probably seems yawn-inducing.
This ring copies the trend set by Dior and others to use words in jewels. This ring features a faux pearl with the word Oui (French for yes) etched on it. It is available for a modest USD$16 from ShopDesignSpark.
