Has anyone else noticed the significant increase in pricing for BE treated yellow sapphires? I don't know how accurate this info is but I've been told that nowadays virtually ALL yellows are BE treated. Essentially your only chance of getting one that has not been is by buying an unheated gem.

What do you all think of this pricing and where will it go and what are our responsibilities as gem merchants and jewelers regarding pricing?

Jason

For the last 3 or four years BE Yellow Sapphire is becoming expensive, even at sites like www.multicolour.com where the vivid red/orange BE treated Sapphire has always been expensive. David over there was also one of the first sites to disclose it's treatment. BE fooled us all!

But the trouble with natural unheated yellow Sapphire is that many will fade if exposed to sunlight.

I have noticed the same thing. Still can get some decent yellows/golds from the Umba region that are untreated, not in large sizes, mainly under 1ct., but they are quite beautiful.

I have also been told that any yellow sapphire that shows signs of heating is being classified as Be treated.

Yes. I think prices are gone up. I don't know by price but the demand is very high. Earlier only few dealers to buy and they regarded as like something bogus dealer. Now everyone buying. Every corner treating centers.

More important treatment method changed detection almost not possible.

I see it is a much more respected treatment now in the Chanthaburi market than it was a few years ago. They will tell you it is 'pow mai' and still keep a straight face when they quote the inflated price.
It was just a matter of time, it does not fade, it is not dangerous for the consumer, it is usually a better yellow than natural, of course the orange and red is stunning, why would consumers resist forever? Americans are the biggest hold outs, other countries are willing to pay much more for them.
A fella brought me some unheated Mogok yellow the other day, they are not as pretty, what am I supposed to say?
Tony, do the naturals really fade?? Never heard that. Best regards, Lee

Our natural golds in the larger sizes can be way more expensive than our blues. They are still out there but not everyday finds.
Don't know that our guys use BE as a rule, a lot will use heat.

Hello Lee,

( from the article) Sapphires: There are at least seven types of fading and non-fading yellow-orange-brown sapphires (for details see Kurt Nassau, Gemstone Enhancement, Butterworth-Heinemann, 2nd Ed., 1994, pp. 129-140).


and my personal experience

Hi Tony,
Much thanks for that heads up on fading natural yellow Sapphires. I just looked at a parcel of yellows that are unheated/untreated and even though I turned them down because they were priced too high, I now have another bit of consolation that I was justified in turning them away!
Funny, even though lots of people hate BE treatment, we do believe that it, at least, cannot fade. Best regards, Lee

considering that Be treatment isn't expensive to run, and considering that it is applied to junk, I can't see no reason of paying more for Be treated sapphire than what I would pay for junk sapphire. Treatments might make a boring ordinary stone look great, but it won't have turned into anything like rare and valuable after the treatment. IMHO.
The main problem being detection of the treatment.

Since the outcome is low on the really hot colors, once you factor in the cost of rough, which is not that cheap, plus the treatment, which is also not that cheap plus is dangerous, I can easily understand why they can command big money for the cream. Especially once one factors in high demand for those colors.......Lee
