Here's something sure to endure all trends. A friend of mine had some antique jewelry with old mine cut diamonds and wanted them redone. Wanting to enhance the exoticism of these stones I designed them in an updated Edwardian style; using a fleur-de-lis motif and millgraining technique (those bead like outlines on the metal). Articulated and sways freely on the ear.  Surely doing something ultra-modern and angular wouldn't have done the diamonds any justice. Classic cut diamonds in a classic setting. Sometimes tradition is the best option.
