The mark consists of an image of a square so as the corners of the square are orientate vertically and horizontally forming a square diamond shape with a black border around the outside edge, a white border interior and adjacent to the outer black border, a thin black border interior and adjacent to the white border. The background within the bordered diamond shape graduates from a dark blue on the upper side of the background to light blue on the lower portion of the background with a tapered faceted diamond in the foreground and a reflection of the diamond appearing on the background as the tapered diamond is positioned on its tip while projecting beyond the white portion of the border of the outlined square diamond form with the letter "t" in black prominently positioned in front of the diamond. Next to the design are words "Diamond t Ag" in black, underlined with a green line.
