This holiday season there is an upswing of interest in black diamond jewelry pieces and black titanium anniversary rings
This matches the general increase in desire for things black in the fashion world. According to a November 2007 article on fashion trends in Japan, black is on the way back. According to this source, fashion savvy people are creating a unique effect not with colors, but with subtly different materials and textures using black.
As black is now the color of choice, jewelry designers are taking notice. They have been featuring black diamonds and black titanium more often in their designs. Some firms are selling black titanium jewelry, and another designer has new designs featuring black titanium with black diamonds.
