The Trapiche Gemstones !

Everyone should always keep their eye open for some of the neatest and fairly rare gemstones in existance --- the Trapiche Gemstones ! The Spanish word trapiche was used in Colombia with a literal translation that means 'wagon wheel'.
.
It was and still is applied to a rare form of Emerald that has inclusions aligned along the edges where the crystal faces meet, which causes the stone to literally look like a wagon wheel. The most famous and best known is the 'Trapiche Emerald'.
.

A Trapiche Emerald, found only in Colombia at Coscuez, La Peña in the celebrated Muzo mining district
.
But......the trapiche 'wagon wheel' formations can indeed occur in other types of gemstones, i.e. Ruby, Sapphire, Tourmaline and particularly in a form of Andalusite. So the term 'Trapiche' must be clarified by adding the name of the Gemstone along with it.
.

For insatnce Trapiche Ruby, of which there are two distinct types, one with the carbon 'wheel' from Viet Nam and the second with the lighter colored 'Calcite' or 'Dolomite' wheel' from the Mong Hsu region of Myanmar (Burma).
.

A Trapiche Sapphire, probably of Burmese origin.
.

A Trapiche Tourmaline, of this green variety, can be obtained from the Kavungu mine in the vicinity of Jivunda southeast of Mwinilunga in northwestern Zambia.
.

A Trapiche Andalusite, called Chiastolite, has the same kind carbon spokes as the Emerald and Ruby. This particular form of Chiastolite is found in areas around Georgetown, California. It is also known to many as "The Cross Stone" in religious circles.


.
And I have been told there is a Trapiche Garnet, but have never seen one or even a picture of one, so definitely something to look for.
.
Pictures from own collection and those of some close friends. The locations indicated are where these particular speciems originated from.

but the Show goes on, and the weather clears again.

There is plenty to see, masses of rock and minerals all over the place, inside and out.

Tables of new material, like Imperial Sarah Jasper,

or buckets of everything and anything imaginable,

and hugh slabs of Tigereye and TigerIron,
or maybe even some unknown wierd stuff.
How about a Geode big enough to stand or sit in
.
and a few odd things also.
.
Whatever you want, you could probably find it at QUARTZSITE and for sure at the following Tucson Gem Fair 2010. Many of the vendors at QUARTZSITE will move to Tucson as the various different shows open up there during the month of February.
