The name Tiffany & Co has such a ring to it. And say Tiffany and diamonds in the same sentence and it starts to warm up, particularly when the diamonds in question are sunshine-bright yellow diamonds. These fancy yellow diamonds (and the term 'fancy yellow' is a technical grading, not PR puff) are ripe with colour, even on the dullest winter day. As well the stuff of dreams, hundreds of thousands of pounds solitaire rings and earrings, there are more affordable variations such as the Diamonds by the Yard pendant designed by Elsa Perreti. Tiffany & Co is exemplary in its commitment to knowing where materials come. When the firm went public in the late 1980s, the increase in size meant that it made business sense to produce most of its jewellery internally and so vertically integrated its production processes, controlling every step of production from mining to smelting. Likewise, these yellow diamonds are sourced through an agreement with Gem Diamonds' Ellendale mine in Western Australia. The agreement gives Tiffany & Co. exclusive rights to the mine's production of fancy color yellow diamonds over its full economic life. " The agreement gives us a unique opportunity to extend our diamond authority with exceedingly rare fancy yellow diamonds," said Jon King, executive vice president of Tiffany & Co. " The collection underscores our design heritage with settings that fully reveal the stones' natural beauty and warm yellow color." This also means that every diamond has a traceable origin, something that cannot be said of all diamonds on the market, where batches rather than individual diamonds are certified. And coloured diamonds are rarer than their white cousins, with only one in 10,000 making the grade. So if you want to spread a little sunshine, you know what colour diamond to chose.
