Hello David
I have not a good command of English, but if I understand you ask
what could be the black metal thatyoung people wear. I work in Italy
for several companies, one of them was using a process know that PVD
process with gold, but you can use on other metals (in this moment I
use on casting pieces of steel and we make PVD process in black) you
can get all colors, and is very strong, practically is the coating
that is used on firearms. May be colored titanium heat (I’m working
on to make Flowers very expensive collection with pave diamonds), the
difference between steel and PVD process is the production costs,
other material broadcast is Carbonio, i drawing a collection with a
producer of this material, this week i was in Basel fairs and i show
men collection with white gold and carbonio use it only in plate.
I hope to be useful if you need are at your service greetings
