Hi Gérard, I think most collectors of aesthetic minerals love beryls. It is a very precious and beautiful and thus always expensive mineral (not matter if aquamarine, morganite, heliodor, goshenite, red beryl or emerald), so that I can't collect as much of them as I collect fluorite or galena or quartz. If money wouldn't matter I would have a particular display only for specimens from the beryl group ;-) But there are only a few beryl specimens in my collection and they are all among my most beloved specimens. I agree that emerald is the most thrilling beryl, but aquamarine is also one of the most beautiful minerals for me. And there are several other beryls on my wish list, e.g. red beryl from Utah or a nice morganite from Brazil, California or Pakistan ...

... But that doesn't mean that I'm fed up with your green beauties :-)

Hi Tobi,

For sure we share a common attraction for hexagonal crystals!

Outside their intrinsic quality, what makes the Colombian beryls particularly desirable to me is the association with other crystals and the variety of host rocks they grew up over. I seldom collect floaters, no matter the quality of the crystal (with the exception of clusters and intergrown crystals).

Am also fascinated by the diversity of crystallization patterns which are frequently seen on Colombian beryls. They can be found on any part of the crystal. They are more often seen on the terminations but they can also occur on the prism faces.

As part of my New Year's resolution, I solemnly promise to stick (mainly) to beryls over the coming months :-)

Interesting emphasis on Colombian Beryl. Do you focus on Colombian emeralds strictly or do you have other specimens that you can share ?

Colombian emeralds also share some controversy especially with them being in-matrix. It is normally very difficult to detect whether they have been manipulated into the matrix or whether they came out this way. This problem is not so much encountered with other famous emerald localities such as from China or the Urals Region in Russia.

We do! Several hexagonal minerals are among my favourites besides beryl (fluorapatite, pyromorphite, vanadinite).

PostPosted: Jan 01, 2015 14:02    Post subject: Re: Collection of Fiebre Verde - New Year specimen  

Vitaliy,

On second thought I should have maybe re-opened the Green Beryl vs. Emerald debate… An easy one compared to the issue you are raising :-)

My main focus is Colombia although I have a handful of non-Colombian beryl specimens (Afghanistan, Austria, Brazil and Zambia). I will be sharing some of those too. As per my collection, Colombia is where everything started. I was posted in Venezuela for a couple of years in the late 90’s and I could easily commute between the 2 countries. At that time I had heard about the uniqueness of Colombian emeralds and wanted to find out on the spot what they really looked like.

The lucrative La Pita mine had just started to be in full operation and the matrix specimens were literally flooding the local market. Prices were relatively reasonable and there was no room for the fake specimens market to grow.

The situation turned over in the early 2000’s where the production started to slowly decline. Over the past decade annual production has slumped to 2.6 million carats from 9 million carats and the prices have skyrocketed for both cut and in-matrix emeralds.
Needless to say that all this gave a boost to the fake specimen industry which is now flourishing, not only in Bogota, but also in the mining areas (I guess because buyers have the perception that everything is necessarily natural as you get closer to the mine entrance which of course is a misconception).

All this to say that the controversy you are mentioning is very topical. The fake specimen industry is able to survive thanks to a handful of extremely skilled “craftsmen”. By the way, the dealers in Bogota use a slightly different expression to name them but I won’t disclose it (Not appropriate in this forum…).

So yes, you are right, it is extremely difficult even for a trained eye to identify the glued-specimens from the natural ones. Whenever I visit my favorite dealer in town, I ask him to show me the latest fake specimens on the market. He caters to a Canadian client who is only interested in… fakes! Nice, well balanced and colorful crystals are not just clumsily glued in a hole which has been dug into the matrix but the contact area is artistically designed from scratch using natural crystals. A lot of time is spent on the finishing touches to give the specimen a natural look, even under close visual inspection. All this to say the only way to minimize the chances of getting fakes is to be cautious (too nice to be true) and stick to reputable channels and reliable people. Despite the risks of being fooled, I mainly stick to the Colombian emeralds not only because they are beautiful but because they also offer the widest variety of crystal associations and host rocks.

Happy New Year to all the forum members and the FMF staff!

PS: It was said that the year would start with a non-Colombian beryl. Here is a specimen from Panjsher – Afghanistan.

PS2: Thanks for your comments Don!

Thank you Fiebre Verde. As a fellow beryl collector I enjoyed viewing and looking at your Colombian emerald collection. I primarily focus on other localities but wouldn't pass up a chance at an affordable Colombian emerald in matrix.

I also remember as a youngster dreaming of owning some Colombian emeralds, particularly from Muzo or Chivor. There are few localities that can rival the material and quality Colombia produces and I have not seen many specimens that rival Colombian material.

In your opinion what percentage of floater or separate emerald crystals that are found in matrix are actually fake and what percentage are genuine. I would assume that during mining operations, the specimens that are found in matrix are in the very low percentage and most are usually loose crystals after crushing or separation from matrix.

Thanks for your comments Vitaliy.

I tend to think like you when it comes to Colombian emeralds vs. the rest of the world.
With maybe the exception of Afghanistan (Panjsher) but the production is scarce and very few specimens make it to the market.

I am not aware of fake floaters or fake individual crystals in the Colombian market.
There are so many loose crystals around that there is no need to grow synthetic emeralds. Unlike the cut stones but that's a different market.
In the specimen market, the only fakes they produce is by gluing (smartly) natural crystals into natural matrix.
Sometimes they get a bit too zealous and they use crystals from different mines on the same matrix hoping that the specimen would fetch a higher price.
Difficult to give an estimation on the percentage of fake specimens as I tend to stick to very few dealers I trust. When asking them about the number of fakes, the answer comes out always the same: "a lot" (not very helpful..).

Yes, during mining operations the main focus is given to extracting crystals. Extracting crystals along with the host rock has never been a priority unless the crystals are really too small to be extracted individually. I think the problem lies in the culture of the "guaqueros" (the miners). They just don't understand the value of a specimen for collectors. And when a sizeable specimen comes out intact by miracle, it's chopped into smaller pieces with the hope that the cumulative value of the individual pieces would be higher than the original piece value.

Now I have to make a confession Tobi: Chivor is my favorite Colombian locality.
I will try to explain why over the next few months.

PostPosted: Jan 03, 2015 10:27    Post subject: Re: Collection of Fiebre Verde - Chivor  

Chivor at its best.
In spite of its relatively small size, this specimen has it all: crystal association, clusters, complex terminations, color, uncommon crystal habits, and last but not least a brownish crumbly limestone host rock which contains layers of iron oxide.
The emeralds are a bit saturated and might not have the optimal Chivor hue and tone but it's difficult to get hold of such a well balanced specimen.

Chivor "Sparkling green".
Not as saturated as Muzo but very intense and with a slight bluish caste.
Out of the six terminated crystals, only one has a pyramidal termination (the leftmost one on the first image).
Host rock is black shale (not featured in the images).
Longest crystal is 12mm.

Excellent Chivor pieces. My favourites have always been from Muzo or Chivor mine personally from Colombia.

Out of curiosity I was looking at the pricing for even small microcrystals on matrix from the localities and they range in hundreds of dollars for about a 5mm crystal to thousands of dollars for a 1cm+ crystal. That's pretty pricy and expensive.

I think it's more interesting that I can get an individual emerald crystal of the same size without matrix for 10x+ less expensive. I guess it shows how much matrix pieces add to the pricing.

Thanks Vitaliy.

As per your last comment, this does not come as a surprise.
Specimen extraction is not part of the mining culture in Colombia. This is not Sweet Home Mine in Colorado and specimen mining in the Colombian emerald districts is almost an undisclosed activity. The idea that cash flow can only be generated by cut stones is still very much anchored there. Matrix pieces market is a seller's market.

Hi Gérard. It is a sad state of affairs, as often a crystal on matrix is pretty but not faceting grade due to flaws etc. In Zimbabwe (and I am sure in many other places), the same mentality reigns.

PostPosted: Jan 04, 2015 10:42    Post subject: Re: Collection of Fiebre Verde - Muzo  

A Muzo specimen with what I believe is Parisite. Not a single complete crystal but color is self-speaking.
Parisite is not uncommon in Muzo and they do combine with emeralds.
Calcite rhombs have a sparkling lustre and range from white to translucent.
There are 4 emerald crystals, main one is 10mm long. Slightly saturated green, quite common in Muzo.
There is a small patch of host rock in the back of the specimen (black shale).
