A sky-blue turquoise with minimal veining is typically considered to be the most valuable, though in some countries, blue turquoise with black veins or complex matrix patterns are more desirable. The blue in turquoise comes from traces of copper, and green comes from traces of iron.
Although turquoise is rather soft compared to many other jewelry gemstones 5 to 6 on the Mohs scale , it is very often used in jewelry. Turquoise is one of December's birthstones.

The side-bar story of astronauts on the space-station appears to have been added in to serve as an arc for a sequel and didn't really add the the main body of the novel.
