The cut is atrocious (sorry, I can't think of a better word to describe it). There is a window in that stone the size of a house, but the color is pleasant. I personally don't think I could spend $7K to buy a stone that only has faceting on the very edges, and I could see directly through it. You might as well buy a cabochon then (at least they're typically much less expensive than their faceted counterparts).

Even if it did have a better cut, what lab denoted it as unheated? That is very important.

Is there any proof that the sapphire is untreated? The price seems suspiciously low, even if I account for the giant window. As TL said, most of the stone will be lifeless and dull due to the poor cut of the stone, with the sparkle limited to the very edges of the sapphire only.

Glad to see I am not the only one who thinks the window is massive on that stone!

I like the colour though, however, not the cut.

atrocious - I learned a new word - thank you!!!

The cut is a good example how to waste a beautiful material

Color is nice - sad what happened to the rough.

7K - never ever!!!

Just from what I've seen online, I think that if you got it recut and even came out with a well cut 6 carat stone ( assuming that's possible for this one), that an unheated sapphire of that size and color with a good cut would be worth well over 7000. But that's just my opinion.

IMO it's unlikely the cut of the stone can be saved with keeping that much weight. The cutter probably won't have enough material to work with. If you look, for examples, at gemfix.com's sapphires the stones with 6.2-ish depth are around 3-4ct. There is also one that is 5ct, though.

Before we can discuss recuts, we need to know which lab, if any, denoted untreated status.

Based on the current depth, I think if recut, the sapphire will likely fall under the 5 carat mark and with such a drastic material loss, it is guaranteed that both the tone and saturation will also be severely impacted, further reducing its value. The sapphire will likely end up a very pale icy blue.

I will agree with everyone else here; the color is very lovely but thats a window you can sing through.

 

[PieAreSquared]

$7000 would be suspiciously cheap for an unheated 8+ carat sapphire. But this should have been cut to a ~5 carat stone. Would it then be worth $7K? Possibly, but I would not take the huge chance that it would re-cut well; the color will change.
I agree with Marlow, this is a sad waste of material.

Do you this this one has window also or not? Asking price is $10,000 but it's smaller stone!

Gemstone Blue Sapphire

Origin Ceylon ( Sri Lanka )
Treatement Natural & Unheated

A window is an area of a stone that has facets that are not cut at the correct angles to reflect light back up to the eye through the stone. As a result, the windowed area of the gemstone will not sparkle, because the light is going straight through the bottom of the stone. It is called a window because you will be able to see directly through it - if you were to hold a stone with this trait over words in a book, you would be able to see the words through the stone. With a stone that is cut to the correct angles, you would not be able to see the words, you would only see the sparkle.

It is considered an undesirable trait, although some people are able to overlook it if the stone has a good color/cost/desirability combination.

 

[dk168]

I can still see a bit of a window in the second stone, however, it is much smaller than the one in the first stone. And the colour is nicer to me.

The cut is still not great though, and I am unlikely to part with 10k USD for it.

For that kind of money, I would rather contact one of the precision gem cutters for their help.

They may have suitable roughs in stock, or they could source them accordingly to clients' requirements.

This would work if time is not of the essence, as sourcing suitable rough could take time.

I am no expert though, just a consumer still have much to learn about CS.

I'm sorry but I will not be happy with your second choice for $10K either if it is for me. Again, I am highly skeptical that such a large sapphire, window and all, going for $10K as unheated. Does this stone come with a GIA, Gubelin, AGL, or SSEF lab report? If not, your stone may not be unheated as stated.

In addition to the window, the stone also has noticeable color zoning. I would have no interest at all in purchasing it.

Also, OP, please note that while kind of you to think so, we are not professionals here, but individuals with strong opinions.

There is another online site which is geared towards professionals. If you google "online gemology sites" it should be the first or second returned.

I don't think they're as picky about color though, but they can give information on treatment, and other scientific concepts related to gemology.

 

[pregcurious]

They both have a huge window, where the color looks much lighter (in the center). Do you see how the edges of the stone are much more blue?

 

[LoversKites]

Please tell us who said these are untreated (the seller, a lab).

 

[swissmiss]

The cut on the second sapphire also seems very asymmetric to me. Please ask the vendor to identify what lab (if any) has determined that these are natural, unheated, and/or untreated stones.
