On Strange Gem Materials

Pictured above is a new pendant I made recently and it has a title ("A gold stream oozed out of hematatia"). For those of you who know me a bit, you are aware that I make up new imaginary planets for different gem materials (hence the title). So what is this material? Well apparently not even my gem dealer was aware of the proper name (I believe). It was sold to me as hematite after magnesite but after doing a little research I believe it is actually hematite after magnetite. The word "after" means that at some point there was magnetite there but it chemically morphed into hematite over a period of time. As a gemologist I am always intrigued by materials like these. I don't get as much opportunity these days to work with pieces like this (it wouldn't exactly make a good engagement ring stone!) but occasionally I see something I like and can see the possibilities for it. It's hard to see in this picture but the gold wire in the center does actually come out from a hole near the top of the stone. There is a .10 ct. ideal cut, "E" color, VS clarity diamond at the top as well.
