Pricing on Chrysoberyls?

glitterata said:
I've been wanting a v-chrysoberyl for years. I just snagged what MIGHT be one on TRR (alerted by the SGBTP thread). It's about 2 1/4 carats, fairly pale, and not a great cut, but it looks to be the right shade of blueish green. Or maybe it has too much yellow for v-chrysoberyl. We'll see... (Apologies for the thread jack, Odyssey!)

Oh congratulations!! I am so happy for you! Love when people can snag something they are after. It's so pretty!
I do not consider this a thread jack at all-- We are discussing all things chryso!

Oh finally, it’s been gone for months! I was starting to think the business had closed.

Oh wow, I did not even realize!! Is he still cutting gems? His website seems untouched and his last IIG post was Sept. last year. How have you liked the concave cut? People seem very divided about it. I've never seen one in person.

I know he's an older gentleman, as he's been cutting for many years. But I'm not sure if he's still active. I bought the gem already set from one of his customers.

Do I like concave cuts? Not particularly. lol I mean, I enjoy the novelty of them, and they're VERY bright. But they don't sparkle the way brilliants do nor do they flash the way steps do. They just sort of have their own personality. I'm glad to own one, but it wouldn't have been my first choice. However, I'd been looking for a large "neon" chryso for ages, so I'm happy I grabbed it!

I have not seen this topic come up lately. Anyone know about current going rates for yellowish-green chrysoberyls? I found a really nice one that is yellow-green that the vendor is calling vanadium. He even has a lab report from GRS saying it is vanadium chrysoberyl. I am no gemologist, but I did not think it possible for a yellowish green chrysoberyl to be classified as vanadium. I even found an article on the subject stating, "Ultimately, the visual colour, i.e. the predominance of a ‘mint’ green to bluish green colour is key to recognize and appreciate this attractive colour variety of chrysoberyl," which I will link below. Vendor is asking $3000/ct, which seems a bit crazy to me. Am I off base? The more I talked to vendor, and after sending the article, he said, yes maybe the stone has little vanadium in it, but it is different from normal chrysoberyls. I mean, it is still within range. So am I hopelessly out of touch with pricing on yellowish green chrysoberyls? :confused: This is a large stone at 8 cts. It is an Asian vendor. Perhaps the bigger question is how could the GRS lab deem this stone vanadium??

PS--it is not cat's eye. Here is a picture:Chrysoberyl 8 cts.JPG

Vanadium chrysoberyl - SSEF

Vanadium as a colouring element is quite often underestimated, mostly as it is often associated and acting together with chromium, a chemical element with a similar geochemical behavior and paragenetic occurrence but which is historically better known in the trade and easier to detect with...

I talked to my partner in Sri Lanka, he’s a rough stone dealer. He said vanadium chrysoberyl has a slightly different color compared to other chrysoberyl varieties because of the vanadium, so they sell it as a rare stone.
 
I think the cut on yours does look very beautiful . It just glows, so I did not realize it was concave! I need to look at one in person for sure.

Thanks for the inside scoop. How difficult does he find getting non-vanadium yellow- green?

You'll notice they sort of scintillate more then anything. But like ZERO extinction, which is cool. So the brightness can be quite impressive.

Just saw it! That is really amazing! When you said about the cleavage--I know some stones have that issue, but why does that make it a better candidate for a fantasy cut?

So when a stone has distinct cleavage, that means it splits (or "cleaves") along certain growth planes. That can make it tricky to cut. When a stone has poor cleavage, a lapidary doesn't have to worry (as much) about damage while trying to cut a complicated design.

Oh, I see! The same reason we have to worry about wearing rings with stones that have high cleavage, the lapidary has to worry about cutting them. Makes sense and why so many fantasy patterns are in quartz.

Yep, that, and also because it's plentiful and inexpensive in large sizes. Free to experiment with imaginative cuts!

It's really a matter of large material is available for not a large price. With most gems, when buying rough, as the size goes up, the price per ct goes up. This isn't true with quartz and blue topaz and a few other stones. The fantasy style cutting can show up more easily in larger stones, especially if some hand carving is done.
Topaz has a perfect cleavage plane, so you don't want to have that plane parallel to the table, other than that there isn't much to concern your self with.
Often with fantasy type cutting you can get a much. higher yield from a stone that if you did a more traditional cut, so that kind of offsets material cost, however the time involved in cutting can be a lot lot lot more.

It's a smaller market for fantasy cut stones, so if you had a nice say 30 ct sapphire, and did some exotic fantasy cut on it, it would appeal to a lot less people than a traditional cut. I think people are more open to fantasy cuts on less expensive gems, the more expensive material people are looking for traditional cutting. Just my thoughts, I could be totally wrong.

Thanks for the expert opinion! I really enjoy floral fantasy cuts and have an amethyst cut in one such pattern that I love. The very geometric cuts though I do not like at all. To me that makes a gem seem more like a paperweight in a very modern house. I think you are right that the market must be much smaller for fantasy cuts.

So do you think a halo protected topaz is dangerous to wear as a ring, or will the cleavage plane be safely tucked in the setting (assuming a precision cut by someone who knows what they are doing with topaz)? I always wonder about the safety of topaz in a ring.
