As promised in the previous entries on Adler, I have some pictures of their recent experiments in Titanium. Although relatively common on Earth, Titanium was only purified and used in bulk in the second half of the 20th century. It is commonly used in watches, but rarely in jewelry. One of the aspects of it that Adler leverages is the ability to anodize the normally gray metal to a rainbow of colors. All pictures from Adler, unless noted
Fiocco broach, set 826 diamonds, totaling 38ct. Here the Titanium was probably chosen to produce the bright fuchsia color. Notice how the strips of the ribbon are constructed of separate strips of metal, similar to the sapphire ring.
Autumn Leaf broach, set with 20ct of white and 40ct of brown diamonds. Here the lightness of the Titanium allow for a shape that would have been otherwise too weak to support itself
Ventaglio (Fan) broach, set with white and cognac diamonds, and a 5ct pear-shaped white diamond drop. The Titanium's strength permitted less structural metal than would have been needed with Gold or Platinum, allowing the diamonds to entirely obscure the structure.
Sail earrings, set with 73ct of pink sapphires and 7ct of white diamonds. Here all of the properties of the metal are on display: it has been anodized to highlight the pink of the sapphires, no other metal could permit such a fine structure support the stones and no ear could support even that much Platinum or Gold without drooping to the floor.
