Without being able to examine all of them closely and fully, just having gold flecks in them does not conclusively mean they are lapis because other stones such as blue goldstone also have such flecks. Lower grade lapis actually may have more white flecks and streaks.
There is also no such thing as "blue malachite", since malachite, by definition, is green. It sometimes occurs in the same formation as azurite (or they are ground together and formed manually into a bead or cabochon or whatever), and is then called azurite malachite, but that in no way describes what I am seeing here.
These really need better photos, and really, at the end of the day, a gemologist to examine them if you really want to know with certainty.
Since they are strung with what look like Czech glass or crystal, however, with what appears to be brass chain, I would not be making book that they are in fact lapis.
