Chryso Opinions

[JewelFreak]

Need your input on this chryso, knowledgeable folks. Good size. A little toward green (don't see any on my monitor, though) is ok with me but not any brown or orangey. Does it look like the culet is off center, or is it just not posed straight up? Price is just under $107/ct. I'm just not crazy about the cut -- what do you think?

Thanks!

I have always thought that stone looks very promising. Plenty of material for a recut if you want. My only question, and I have said this before, is that in most of the pics it appears to be doubly refractive, which chrysoberyl is not. I think it could be a great stone, but get it tested and make the sale contingent on it testing as chryso, not zircon.

Thank you, VL. I wondered about birefringence, but also about lousy photography -- so it's been hanging around that long, eh? The math looks pretty indisputable on it. Really informative thread!

Chrysoberyl is double-refractive...

Just less pronounced than a Zircon or a Tourmaline.

 

[VapidLapid]

If you want to police the vernacular speech please be complete. All our gemstones are birefringent. Some show this property to the unaided eye. Others require optical apparatuses to observe, and measure their birefringence. In zircon, whose birefringence is .06 the phenomenon is easily seen. In chrysoberyl, the birefringence is .011. Specifically, birefringence is a value of the difference in index of refraction of the ordinary ray (on the optical axis), and the extraordinary ray (perpendicular to the optical axis) in a material.

Looks more like a sphene, and yes, zircon comes to mind as well.

Laurie: assuming you take care of VL's concern and find that it is definitively a chryso, then it looks to have good color and I personally love cushions. If you care about price, then know that the price per carat sounds good if its a large chrysoberyl (say 2.5+ cts), but a bit on the high side if its under this size. HTH. My one cautionary thought is that it looks awfully yellow to be a chryso, but that could easily be due to monitors and vendor photo post processing edits.

VL,

Not every gemstone is doubly-refractive and exhibits birefringence. Diamonds, Spinel, and Garnets are singly refractive.

Sorry for the threadjack, carry on!

That's why I put it up here, Minou -- I missed the earlier thread (or forgot after 3 yrs), but it looks very yellow for a chryso & the birefringence made me wonder. And if it was poor photography or editing, neither gives me a lot of confidence. I'm not crazy enough about it to bother, actually. Usually if a stone sits on a site for that long, there's a reason. Got to make your heart thump to give it a try & this doesn't. Thanks for the info & advice, everyone!

Laurie: have I told you how much I adore you lately?!! You are such a good PSer and are so clear in what you seek. And yeah, your point about poor photography/editing is well taken.

Aw, moi? Back at ya, honey. Besides, you're smarter than I am!

can I just ask - and sorry for the threadjack - does this chrysoberyl have good color for a chryso, or do you mean it has good saturation? just trying to learn more about them, and the ones on PS seem to veer toward the neon (vandanium out of question, of course).

 

[corundum_conundrum]

I love this color if its a chryso.

I prefer the yellower-colored chrysos with minimal green that are intensely saturated. I agree that the preference on PS for Chrysoberyl slices toward the neon-yellow or chartreuse stones with vivid saturation.

Good question. What I meant by good color is its saturation - which appears to be quite good. While I've seen many of lower saturation with a brownish cast, and many with good to vivid saturation that are greenish or neon yellow, I have never seen a highly saturated chrysoberyl of a pure yellow - almost a gold yellow as this one appears in the photo. It makes me think that either they amped up the saturation on a stone that otherwise might appear a bit brownish, or it may be a stone type other than a chrysoberyl; one that is more likely to come in that bright yellow - such as a sphene, or maybe a zircon. Does that help?

thanks, it does! during my earlier search for a chryso, most of PS spoke for the bright neon - and so I, with my very limited (and never knowingly IRL) experience in chrysos thought that was the HG color, so to speak. luckily for me though, my taste seems to veer to the not-so-neon greenish-yellow chrysos that are in greater abundance and of lower demand - which makes my options cheaper!

 

[JewelFreak]

My first question on seeing this on the vendor's site was the color. It's a very pure saturated golden yellow for a chryso, more like a zircon. Given that & the obviousl birefringence, I kind of doubt it is a chryso. The vendor is reputable & may have been told it is -- it has no note about having been tested, so I assume it hasn't been. Chrysoberyls are, for me, really hard to judge from photos -- almost all show some brown, but it usually disappears in videos & in in-hand pics PS buyers have posted of ones they've bought. Feedback from here therefore interested me.

P.S. I like the greenish-yellow ones too.

Sometimes a stone sits in inventory for a long time because people don't really "see" it, not understanding that it could be a good purchase. I'm hoping someone checks out this stone because I've been wondering for the longest time whether it is a chrysoberyl, zircon, sphene or something else. Sometimes items are mislabeled / misidentified when a vendor has hundreds of gemstones to list online.

 

[OTL]

I also considered this stone before, and asked the vendor whether he can do a handshot
But he said sorry but won't have time to do any photography in the near future which kind of turns me off.
I don't think I will buy from a vendor refuses to provide additional pictures. Just make me feel less confident.

I don't get it why they won't if they're willing to do a sale. Yeah, that's a big turn off to me as well.

If you don't know how to take a proper photo of a gem, then I can see why it would "take too much time." Personally, I think if you're in the gem trade, especially online, you should learn how to shoot your gems, and provide videos too, which is an added plus. JMO.

Could not agree more - if we can do it, then those in the profession with a vested interest in selling stones, should absolutely do it, whether that means learning themselves, or hiring someone to take photos for them. I don't understand when vendors complain that its too much work.

 

[JewelFreak]

Especially when a stone has been for sale on your website for at least 3 years. Small investment to take time to snap a few photos & get it out of inventory.

So I was going to make an offer, but now it is not even in my watching list anymore

 

[JewelFreak]

Give it a shot, OTL, why not? You might get it for less & we all are curious about it -- could be a keeper, you know!
