About Platinum

There's something your grandmother or favorite aunt has in common with Eva Longoria, Katherine Heigl, Rebecca Romijn, and yes, even Beyonce. They all selected platinum as the metal of choice for their engagement ring. Why has platinum stood the test of time? For starters, it's a natural white metal that won't cast any color on diamonds. And its density makes it more durable than other metals. But it also, quite simply, just feels perfect when worn as a symbol of your love. Robbins Brothers is pleased to share with you the following facts about the pure beauty of platinum.
