“Square-cut or pear-shaped, these rocks don’t lose their shape!” Marilyn Monroe’s dazzling performance of “Diamonds Are a Girl’s Best Friend” in Gentlemen Prefer Blondescarries a simple truth: Whatever you want to say, nothing expresses itquite like a diamond, and few things last as long (diamonds areconsidered unbreakable, after all). Although in 2009 the industry was,unsurprisingly, hit by a dramatic slump, the latest annual report by De Beers,the world's largest diamond producer, predicts a speedy recovery by theend of 2010, suggesting that, as ever, these particular gems are amongthe world’s most resilient—and coveted—commodities. As with any gift,choosing the perfect rock can be painstaking, but since December 2009, Bokks,a new luxury concierge service based in London’s Mayfair, has beenmaking things easier. The Bokks team kindly selected this portfolio ofadamantine presents from its impressive inventory of high-end brands.
