Yellow Sapphire

[Double E]

Yellow sapphire seems to be a lot less discussed here, and doesn’t look like favourite of many. Is high quality yellow sapphire much more common and less rare than say blue and pink sapphire?

And is it any widely agreed hue standard for terms like golden yellow, orangey yellow etc.?

When it comes to saturation, particularly for yellow sapphire, is the highest saturation only achievable by heating the Kowangu type Ceylon rough?

Wish someone shed some light on it and discuss~

Yellow is not as desirable a color as blue red and green in any gem family.
Yellow untreated sapphire is way more rare than blue (or red sapphire/corundum = ruby).
Rarity X demand is what is more important in establishing price or value.
On top of that, with gemstones, locality adds premiums or discounts. I have just sold a huge ruby lab identified as African but with Burmese features including over the top fluorescence. It would be worth 5 to 10 times more if it was Burmese!

Seriously?

Would be happy to get that “cheaper” one with same quality!

Yellow sapphire isn’t as popular as blue or pink but I believe more popular than green.
My favourite is actually parti sapphires, especially when cut to highlight the two colours.
I have a light yellow sapphire, interestingly everyone assumes it’s a champagne diamond.
Not complaining.

Parti is interesting! I like yellow blue combo more than yellow green~
Yellow sapphire is more appealing to people who prefer brighter gems, I guess. When it reaches a certain saturation level, yellow sapphire seems to perform better or more likely to remain lit or bright in dim or low light than other sapphire varieties of the same saturation level, including blue and pink. But hue is of course personal.

it isn’t surprising someone thought it’s a diamond, although there’s still critical difference in the mineral properties. Yours must be a very nice one^^ And it’s beautiful in its own right~

I seem to also remember reading a few years ago about some yellows being irradiated, but the color not being permanent and fading over time.

 

[nutellakitty]

Some "unheated" yellow sapphires can fade because local dealers put them under sunlight with a metal plate that attracts heat for 5-10 hours and the yellow color will become more vivid. However, they fade after 24 hours. This happens in local market trading.

 

[Double E]

Treatments other than acceptable heating like irradiated or the “metal plate” method as mentioned is definitely something most want to avoid. However do anyone know anything about kowangu yellow sapphire which is said to be a sort of normal heating on some particular Ceylon rough?

 

[PreRaphaelite]

Is Synthetic yellow sapphire common, as some synthetic blue sapphire is? I had assumed it was, but now I wonder.

The only yellow saphire ive ever seen was a lab grown down the mall
its the only yellow stone ring ive ever seen that wasn't citrene or amber outside of PS of course

At the time i thought it looked so fake ....but now i know a bit more

That is interesting. I have pale yellow untreated sapphires in earrings. People ask me if they are yellow diamonds--yet when I look at them I would never see that.

my new earrings are so delightful..

Not common because of low demand

Beautiful especially like the contrast with the blues~

Didn’t imagine yellow sapphire is that uncommon in the market. But trying to recall, it’s actually similar here in my town.

Haha! Don’t worry, I like people sharing what they wear in my threads! That’s exquisite~

Here is DW's 27.51ct yellow sapphire ring that came with an AGL cert stating Ceylon origin, Heat Only, and Intense Orangy Yellow color.



The color does vary somewhat depending upon the light. This photo shows more of an orangy gold color.



The main thing to be careful about with yellow sapphires is treatment. Before we knew better we purchased this lovely yellow sapphire pendant.



We subsequently discovered quite a lot about sapphire treatments here on PS, so sent it to GIA about a year later. Turns out the sapphire was "Beryllium Diffused with Synthetic Overgrowth". Lesson learned...never buy a sapphire without a Cert from a reputable lab !!! I've checked yellow sapphire prices and found that BE treated stones are readily available in the market and, when disclosed, they are less than 10% the price of heat only.

That orange modifier simply elevates the saturation of the stone. I wonder how it performs or how is it’s colour behaviour in really low or dim light. Your stone takes me back to my core question that whether untreated stones can reach that colour intensity.

Being less sought after, yellow sapphire actually offer very good value. You buy bigger costing less compared to other more desired sapphire varieties.

Also, I guess one could get higher level cut much easier in yellow due to lower pricing pressure on weight.

I am sorry for the BE stone. Just as you mentioned, most of us likely pay for some lessons~ Your orange yellow sapphire is simply gorgeous!

Yellow sapphires are a personal favourite of mine. Especially unheated and step cut. Yellow diamonds are out of my budget but you can find amazing yellow sapphires which really sing with colour. The biggest issue is that sapphires don’t tend to “sparkle” unless they are VERY clean so I end up cleaning my yellows every time I want to wear them.

 

[demantoidz]

Having not seen nice yellow sapphires IRL, I can't say for certain, but this vendor seems to have one particularly well saturated unheated yellow sapphire w/ orange modifier in some of the images (on my monitor). No lab report, but they do have stones with GRS, so that could probably be arraged for a serious buyer who is worried it may be treated.

A vivid yellow sapphire ring is high on my wish list. It will have to be berillium treated though because I want a big mofo.

DW's stone performs really well in low light, although it requires good, direct light to achieve the bright yellow color shown in my first photo. This photo would be more typical of lower light situations.




The Dec 6th Heritage Jewelry auction happens to include five good sized yellow sapphire rings LINK None of the stones are heated, and whilst some of them have good color, I don't think any of them could be described as having a high level of saturation. Those with AGL certs are all described as having "Yellow" color. DW's stone is described by AGL as having "Intense Orangy Yellow" color.

DW's yellow sapphire ring is AMAZEBALLS! Prior to reminding me of it I would have said I've never seen one I care anything for. That color is so beautiful. It is absolutely stunning.

This ppgems stone looks well saturated, especially if it’s really untreated.

I followed this IG account. Most if a not all of their stones are big rocks, very intense / vivid if not the tip top colours, and very very clean. Is it even possible?

It’s a beautiful set~ A set of jewellery pieces with same stone variety is very appealing, but also costly…

And it’s on point that sparkle wise sapphire and diamond are different. But I think you agree that yellow sapphire is pleasant on its own~

I know the difference is more apparent with larger stones...but just for fun - yellow diamonds or sapphires?



The hauyne ring was made with yellow diamonds. Soon after I decided to create 2 more to wear as a flower chain but didn't want to spend the money. So I opted for yellow sapphire centers for the other two. In hindsight, I should have made the original with yellow sapphires as they were a fraction of the cost and I have to look really hard to tell the difference.

I must disagree with unheated yellow Sapphire being much more rare than unheated Ruby and blue Sapphire.



Untreated yellow Sapphire is relatively common, in straw yellow and slightly more saturated color. But intense yellow/gold Sapphire is very rare, and I would agree much more rare the unheated Ruby and blue Sapphire. But we have to make a distinction here or everyone will think every yellow Sapphire no matter how unsaturated is more rare. It is not.

I’m lucky I guess in that I usually am more drawn to the lighter hues than the vividly orangey yellow. Cheaper for me! But now I’ve seen that delicious ring and it’s glitzy halo I’m feeling like I’m missing out
