According to this article link, black on black is back in black!  Looks like it's time for me to make some more jet beads, cut some black druzy quartz, psilomelane, black onyx, and who knows what else.  Do you have any pics to share of black on black jewelry or fashion?  This pic is of a black jet mourning heart I made with a tube set genuine black diamond in 14k gold.  http://www.instoremag.com/homepage/shine-blogs/item/987-black-on-black-is-the-new-black-yes-really#!_7PamelaFromanPFFJ_BlackDiamLeatherWrapBR

Completely natural colors!  New work I've done in "Bumble Bee" a travertine (NOT a jasper) that is mined from a hot springs fumarole at the base of a volcano in Java.  Most of this material has alternating dark stripes in it, hence the name.  I got one small chunk of this all yellow material that has touches of orange orpiment in it.  The yellow comes from sulfur in the water that deposits the layers of travertine in the fumarole.
