hi I'm Steve Moriarty from tanzanitejewelrydesigns.com and we're also
jeweler on the square in Crown Point Indiana known as Moriarty's gem art
today I'd like to discuss with you some of the colors of tanzanite they do come
in a wide variety of colors most people aren't aware of this we sometimes call
them by their color name and call them like pink tanzanite but some people say
it's more appropriate to call it pink zoisite but we generally use the term
tanzanite because it comes out of the same mines it's not the blue purple
variety but they're really unique colors and other than that I don't know a whole
heck of a lot about them I don't know whether they're heated or not I just
know they're pretty stones and they're really unique my first experience
wouldn't be my first experience by my last trip to Tanzania was the first time
I'd seen my any of these colors available and in such a wide array and a
wide variety up to that time they'd been exceedingly rare pink tanzanite was just
almost impossible to get and in in on my trip in 2014 there were several stones
available and it was just unusual to see I thought I'd hit the mother lode and
turns out that there was a lot more available and it has been available
since then a little less now but still available and I'm going to show you some
of the colors that that you'll see you know of course we have tanzanites like
this which is what we expect the color out of tanzanite although this
particular one it's a natural color and when you look at it between daylight and
incandescent this is a color changer it will change probably 90% from blue
completely blue in daylight to almost completely purple in incandescent
lighting so this would be a color change stone whereas most of the tanzanites do
color shift meaning they have a lesser degree
color change so that that one is a natural stone this is what we expect
from natural tanzanite more of a brownish look this is a natural
tanzanite that will heat to a beautiful color blue if I decide to heat the stone
but it's very pretty as it is they call this color diesel because it kind of
looks like the color that when you look into a can of diesel fuel it's kind of
brownish reddish bluish kind of color that one will heat to a beautiful stone
this is a heated tanzanite but it's kind of unusual because it's mostly blue this
stone has very little purple in it you go to incandescent and it generally
stays blue this next one some people call it peacock chameleon it basically
is a blue tanzanite that has a lot of green in it the rough will not display
any of the yellow coloration it is just mostly blue purple and green and this is
the kind of color you get out and surprisingly it's been a pretty popular
color with people much like the kind of steely blue spinel is just a popular
color at this time now we get into some of the fancy colors you know whether you
call it tanzanite or zoisite here's a purple one again I don't know whether
these have been heated and it'll be impossible to tell other than the person
that heated it I don't think the labs can tell you whether these are heated
but kind of a unique color then we have yellow this is kind of a greenish yellow
color
and another another one that's got a little green tint to it and yellow and
this is very beautiful stone looks much like Malaya garnet similar to papaya
sapphire this is a peach color tan tonight and this is probably much rarer
than the yellows or the purples and then maybe the rarest color and this is
really a great one is the the pink zoisite or pink tan tonight so these are
about as many colors as I've seen in tanzanite there probably are other
colors what causes these colors I personally don't know and they're rare
enough that the labs they'll get much chance to to really examine them I've
not read anything on them all's I know is they're all pretty colors and I'm
just happy to own them thanks for watching I'm Steve Moriarty from
