I stand corrected.
It is conveniently listed in the colored stone section under Blue and Brown.

I was looking for Zircon.

I have the online version.
It contains an alphabetical list of gems, which for me, is not intuitive:

One would think they could also be listed again, under Z
Zircon, Blue
Zircon, Brown

You also have to be careful of what prices you are talking. The appraiser was talking of wholeseller prices if I read correctly, some of the other prices mentionend (300-400/ct) seem to be endcustomerprices to me.
So here is also a big difference. Also Bonhams will normally sell to endcustomer prices....
Just my to cents.

I also think the prices really depend on the size, as the auction prices seem to reflect. The value guide mentions stones 10 carats and up to be the same price per carat, but in my research from Bangkok, a ten carat stone would sell much much cheaper then say a twenty carat stone per carat because of the size, not quality, simply because of rarity of larger stones.

There are many 10 carat stones available but once they are in the twenties, or thirties its not easy to find. But the value guide doesn't really take this into account. So how would one value a 40 carat zircon? or 50 carat zircon? The larger sizes usually end up in museums since they are so rare, such as these.

Geology Museum, London: 44.27 (blue); 22.67 (golden); 14.34 (red; 21.32 (white).

Anyways for these larger stones, i think the only way to determine the value is by auction price. So when doing an appraisal, looking at auction prices might be the best way to go to find the accurate market prices. Anyways, just my rant, Thanks for the replies.

There are NO "wholesale" comps for 20-35 ct blue zircon.

The price is determined when an individual specimen is sold.

Analogy:
What is the wholesale value of 1ct. eye clean hauyne?
A 1ct eye clean benitoite?
20ct lavender apatite?
10 ct tsavorite?


Some things, including "arms" zircon are rare and collectable and go directly to end customers if properly marketed. Including museums.

I would spend my money on a GIA report or AGL report. Forget the appraisals. Meaningless.

The value of the zircons will be determined when and if they are sold.

HI, yup, it is meaningless.

This time the value seems overstated for the same stone different appraiser. I have no idea how it got so high!!!!!!!! I was expecting 10-15k, its retail was 58k. I guess the retail is much higher. but the appraiser even said what am i going to do with it??? no one in Canada would buy it because its so deep n chunky that I cant make jewelry with it.

I do agree with Barb, I got it anyway just for peace of mind and a second opinion, i would have to send it away for GIA tho, and i heard its a 2 month wait.

Maybe 2 months for something of this size? I sent a small stone in a while back and it took a couple weeks iirc.

AGL is great too.
Although everyone in the world knows the GIA brand.

does anybody know about paper work involved when sending stones cross border? either to a lab or for an auction etc.

havent looked into that but im sure there is some kind of declaration and paper work and perhaps tax.
