Vietnamese Zeolites!

Minerals from Vietnam have always been somewhat limited to gem species— Luc Yen has long been known for its rubies and spinel (with the odd collector specimen of clinohumite or pargasite), and in recent years there has been an abundance of aquamarine from Nghe An.  


Here is something completely different though: zeolites. 


Good examples of zeolite minerals are actually not that common worldwide— the things is, India has produced examples in such abundance and quality, that I would say it has cheapened this entire mineral group’s image.  But if you think about it, how many other places produce zeolites in such abundance?  The New Jersey traprock is a very distant second in terms of quality (I’m sure this offends a couple people), the various locations in Nova Scotia are probably third— and rarely do any of the encountered species at either location reach the heights of quality found in India.  Everywhere else—Oregon, Scotland, etc. usually just has gas bubbles in basalt with some nondescript small, orange/white crystals…. (EDIT: after I posted this, I was sent a link to the Mindat page for the Skookumchuk Dam in Washington, and those zeolites are nothing short of impressive, but to my earlier point on zeolite rarity those came out 50-60 years ago)


Which brings me to these Viet scolecites… I first started seeing these about 2 years ago, usually heavily damaged and offered as large, Chinese-style decorator pieces — in fact, a few of these were chopped down from carvings that included floral designs and pedestals carved into the basalt matrix. 


Good acicular clusters *on matrix* of this delicate material are notoriously difficult to get even from India, because they are always crushed—I would know, because I always keep an eye out for them, despite not being a huge fan of Indian minerals.  Most of the Viet examples get destroyed as well, but I had particular luck finding examples where the clusters were relatively protected.

VTZ01 Scolecite
Dray Sap Xa, Krong Ana District, Dak Lak, Prov., Vietnam.
11.8x 10.4x 6.0 cm
$600

A beautiful cabinet sized example of scolecite, containing several beautiful acicular clusters, nicely protected in a Vug. 

I first started seeing these about 2 years ago, usually heavily damaged and offered as large, Chinese-style decorator pieces — in fact, a few of these were chopped down from carvings that included floral designs and pedestals carved into the basalt matrix. As such, there are saw marks on the backs and sides of these pieces.


Good accicular clusters *on matrix* of this delicate material are notoriously difficult to obtain, even from India, because they are always crushed-- I suppose the exception would be the oversized, or densely packed examples-- but the more aesthetic specimens with this delicate appearance are somewhat  to find.    Most of the Viet examples get destroyed as well, but I had particular luck in finding examples where the clusters were relatively protected, such as this one.










VTZ02 Calcite with Calcite
Dray Sap Xa, Krong Ana District, Dak Lak, Prov., Vietnam.
13.0x 9.6x 6.1 cm
$485

A nice example of brown radiating calcite crystals, on matrix with another botryoidal mineral.  At first I suspected this white mineral was a zeolite, but looking at the polished cross-section on the edge, there is a banded structure that seems more like a carbonate than the typical zeolite-- and calcite is known to form similar growths in these environments; examples are occasionally seen from Italy and Poland. 









VTZ03 Scolecite
Dray Sap Xa, Krong Ana District, Dak Lak, Prov., Vietnam.
11.6x 11.5x 7.0 cm
$495

A beautiful cabinet sized example of scolecite, containing a couple beautiful acicular clusters, nicely protected in a vug.  One of the clusters has some shearing, but overall the piece is as shown.

VTZ15 Calcite and Prehnite
Dray Sap Xa, Krong Ana District, Dak Lak, Prov., Vietnam.
12.7x 4.3x 3.5 cm
$150

To be honest-- I am not entirely sure what this is. It could be a zeolite, but the cross section of the darker botryoidal material on other pieces makes me think it is calcite.  The lighter colored stuff was sold to me as prehnite... but I do not guarantee it.

I am posting this one to show why the others are special-- this is quite pretty as a reference sample, and it is also unusually rich, but as you can see, even when protected in a vug, many of the crystals do not make it out intact.....
