Dumortierite stone...
« on: August 31, 2016, 12:43:39 PM »

This is a stone I just found on the web, & I think it is very neat, the crystal growing within the quartz is the dumortierite, & this is a good example of the more rare configs. Usually the stone is seen as lapis, blue, opaque & not too hard, in the quartz, @ 7.5 on the mohs scale. This stone is very clean, 10x10x7mm, 2.88cts with slight blue in the crystals, a good example- :hello:

Clear quartz with inclusions is a strong interest of mine.  Here's an image of an uncut quartz crystal with included dumortierite.  Very pretty stuff.  Pricey too!

I was soooo impressed with the 1st stone, I bought a 2nd, a little more intense, 9cts, 15x11x8mm, good clarity with good crystal formation, this is for pendent city, a very neat rarity :cool:

Hello John, Please to inform the material u refer to is different from the dumortierite stones im showing, these are rutile quartz, there is a difference visually & the rutiles are a different material & color. I think the material is called sagenite-steve  :occasion14: :cool:

Spectacular! I love these stones. For some reason, the gold looks yellow in the pictures.
