Heating of Corundum - an investment?

[chrono]

The study of gems is broad in scope and depth, so it is best to do one section, or in this case, gem type at a time. Going off hazardously will only serve to confuse you and slows down the learning and understanding. Do it because you love it and stop putting a monetary price tag on everything. In time, it will fall into place and you can then decide if this is something you would like to start a career in. If so, then formal training like the GIA courses are required.

Jim, it wasn't the math problem that hit me first, it was the logic.

Jewelry Lover, I'm wondering what huberus would lead you to believe you know better than the entire gemstone industry?

I think I'm going to start doing my own surgery. Imagine the money I could save on medical bills!

Seriosuly, this is the most ridicilous comment I've got so far. This one is just pathetic. First of all we're talking about heating Sapphires, I've posted 2 Reports already. I can post more of them if that is neccessary. Telling me I'm almost talking about something that's not possible or non-existing. All gemstones can be heated to enhance their color. Knowing what better? That gemstones can be heated to enhance their color? That one we can discuss forever.

Comparing heating of Corundum (something that's possible) to being a Surgeon without education, that's like 0 to 1 million. And I have to say one more thing about this, if it were so "difficult" to earn money in this industry, people wouldn't be able to earn a freaking dime. If it where that difficult, "poor" people in the poor countries wouldn't have anything to offer us because they wouldn't be able to afford it. And you dont have to be rich to get rich in the gemstone industry. How I know? I know poor people in both India and Thailand that have become very successfull. Hopefully people understand that there's some tricks on the market that do turn something "nice" to something "beautiful".

When I get my 9 Corundums back that's in for heating, and if they turn out well, I will really enjoy re-reading this whole topic. If they turn out bad or without no effect I will admit it and not post anything anymore on this website. But if they turn out well, I hope some people with ridicilous comments shut their mouth and begin to re-thinking if what they know is correct or not.

No one ever knows the outcome of heating a Sapphire, not even scientists. So telling me that unheated gemstones should've been already heaten if it were possible to enhance them, that's just ....

I dont want to piss all and everyone off and I'm appreciating some of the comments that are correct and that make sense. But someone can actually save their ridicilous comments when they dont even can refer to a study or any report that's proving me I'm wrong. While I just did on side number 1.

If it's that hard to ask a question or suggest anything here at all, I really dont understand why this website do exist. People have to understand that something they know is wrong, something is right, something is neither right or wrong as scientist dont even get along or agree. Disagreeing isn't a bad thing, and people really have to relax at this website. Saying my own opinion are like fireing up dynamite somethimes. Even if I didn't mean to.

Telling me I'm wrong ..? Then prove me I'm wrong .. I'm a woman but I can take it like a man! Peace!

Thank you Chrono, I agree, and I will do.

JL,
Gemmologists HAVE studied the effects of heating and can predict it as well. Labs have published many studies on this, which you've seen already. The heaters are not poor and definitely not stupid. If anything, they are way ahead of the labs in what can and cannot be done. They've been running their own trials for umpteen years and are highly unlikely to accidentally let a potential stone through the cracks.

I am concerned that you do not know what you are buying, especially when you mentioned a stone's filling oozing out and having no prior knowledge of treatment. Also, it is extremely common to see stones sold without any papers. For some gems, it isn't necessary but it is imperative for others. If one wants paperwork, it is the customer's responsibility to request that the vendor make the sale contingent on the lab result and the customer pays for it. Most of my collection are without papers except for my sapphires because the rest are never treated, plus I get them from reputable sources, even if from eBay.

Origin often does not matter unless it is of exceptional quality.

I do understand your concern and your opinion about this one. In my opinion Russian Demantoids should have the same paperwork done as requested for Kashmir Sapphires, and as for Burmere rubies. I do know that it's the customers responsibility but at the same time I find it very weird that one are offering Russian demantoids without papers. Thinking that a Report would make it a lot easier for the sales person to sell them as well. And also as a little security for the customer.

A report means added cost and not everyone feels they are necessary, especially if the buyer knows what he / she is doing. Furthermore, reputable vendors (like those vetted by PSers) are honest and no paperwork is required beyond a few exceptions. In most cases, it is fairly easy to distinguish a Russian from a Namibian demantoid, although some Namibian are known to exhibit horsetail inclusions as well.

An astute buyer will save money in the long run by not paying $100 or more for every stone he or she buys. Learning which stones are always untreated, which ones are almost ways treated, spotting doublets, coating and etc goes a long way, and buying from reputable sources is a good way to start.

Kashmir sapphires and Burmese rubies come with reports because the list of treatment is endless. If you want it to sell, then proof must be shown that it is what is as advertised. I've also seen plenty of ugly Kashmir sapphires and Burmese rubies that aren't worth the memo paperwork. Paperwork is not a guarantee of quality. Russian demantoids are also heated without disclosure because the labs are unable to detect this easily.

 

[PrecisionGem]

JL, of the 9 stones you sent for heating, do you know if any of them had already been heated? Do you have any before pictures of the stones? What locations are they from?
It will be interesting to see the results.

Yes, I do trust a lot of vendors myself, I really do, but I'm always extra sceptical when it come to the Russian, Kashmir, and Burmese Origin.

Thank you for your answer Chrono.

None of the Corundum has been heated, I know this because Corundum is the only type of gemstone that I'm most familiar with as well as Corundum is the type of gemstone I can easily see if it has been a treatment done or not. The gemstones are mainly from Tanzania and Madagascar. And yes, I got pictures of all of them, I will post them the same day I can take new pictures of the heating results, so it's easy to compare

Ok - this post is EXACTLY why we know you don't know anything. You have made sweeping statements and your knowledge of gemstones is scant to say the least. To say you can "see" treatments is ludicrous. Haven't you read any threads on here? Do you not realise that you are not an expert and even experts wouldn't say they could do this? Some treatments are detectable to VERY EXPERIENCED eyes. Seriously, you don't have that eye yet.

Actually I think Upgradeable's post comparing what you want to do with trying to carry out surgery is exactly the same as what you're trying to do. If you look back through your posts you will see that you've told us that you're heating stones to try to improve their value (by sums that are just ridiculous). First you say you're going to do it because you have an oven (not even understanding the skill involved) and then you say you've sent your gems off to be heated. This is all in the same day - so you've found somewhere to heat your stones and sent them off despite saying you were going to do it! You can understand why we may be a bit sceptical. If you have sent your stones off for heating, at the very best, you may improve the colour of one or two of your stones (assuming they haven't been heated before and you DO NOT know this). However, the point is that it's unlikely that you'll improve the value by more than $50-100 and then you need to take off how much you have spent on postage, heating etc.

You really must learn that you're on a forum where people know about gemstones. You don't - you're missing even the most basic of knowledge in some cases. You need to learn because these endless ridiculous threads and you not listening or learning is why you're getting the comments you don't like. You're absolutely trying to carry out brain surgery without even going to college. You think by reading Wikipedia and a few online articles you know more than people who have studied and either are in the gemstone business or have been collecting for many years. Please take time to listen and learn. Do not think you know best. Do not make ridiculous assumptions about the locality of gems/lab reports. You simply don't know enough. Even when you ask questions you then challenge, challenge, challenge and it goes through endless pages of posts twisting and turning with you always saying you know best.

I'm sorry if this post is too blunt but if you really want to learn about gemstones you will sit back, learn (from reputable sources) and stop thinking you know best. As I said many pages ago, take a course and learn that way. You'll soon understand what we're telling you, that this is a highly specialised field. People who collect diamonds (see Rocky Talky) sometimes come on here looking or a coloured gemstone and after a few pages will often say that it's much easier to buy a diamond. It is. Coloured gemstones have a myriad of differences and you need to understand them. I'm still learning and have been collecting for over 20 years (actually nearer 30). I don't know half of what I should but I know enough to keep out of 90% of trouble and I'm sure others would say the same.

First of all, it's easier to find treatments in Corundum than in any other gemstone, for me. Second, you got absolutely no clue how, which way, or anything regarding how I know the treatments and not.

Oh my god, yes I will heat some of my stones - I NEVER said I were the one to do it. Neither did I say that I personally did own a oven either. Of course I heat my gemstones, because they're MINE and not the heaters. Second of all, I got reports on all of my gemstones that has been sent for heating - so the answer is: YES, I DO ACUTALLY KNOW FOR 1000% SURE THAT THEY HAVE NOT BEEN HEATED!

I wont post any comments untill the gemstones are back. Then I will post some reports, some before and after pictures. THEN we can all argue again.

Well congratulations - for somebody new to collecting you obviously have a skill that surpasses nearly everybody on this forum (including the lapidarists). May I suggest you pop over to Gemologyonline.com because they'll be very interested to hear all about this.

In the meantime, please post the reports now so we can see all about the 9 gems you've sent off. Then we can see what you've already got, information you already have.

Then I have to apologize for the misunderstanding, I dont write fluent English. But I know I never said that I got an oven, cause I dont. But I do got availbility to an oven, in the way that I know someone that own one, and they will heat them for me because unfortunately I'm not available to go with them to their residence to perform this as they live far away. What so ever, the gemstones were picked up couple of days ago and will be back in ca. 14 days.

Here's 4 of the Reports (certificates), I got more somewhere but I dont know exactly where right now. The info hidden including the pictures at the Reports will be shown when the gemstones are back from heating!

 

[JewelryLover]

Here's two more

 

[LD]

Thank you for posting those. The only reports (they're not certificates) that I personally would "believe" are the AIGS and AGL reports. The others I wouldn't.

I'm wondering why you've blanked out the photos of the gemstones and the sizes? That's a bit strange.

What is even more odd is why you're risking doing this? If somebody has gone to the trouble of sending these gems to a lab then (presumably) they think that they're in the best format as they are. So basically you've taken an unheated gemstone (which is typically worth more) and you're going to heat them - which reduces their value almost immediately? I don't understand the logic of this unless the colour is totally unacceptable in the first instance.

 

[JewelryLover]

Thank you for posting those. The only two reports that I personally would "believe" are the AIGS and AGL reports. The others I wouldn't. In fact I think one of those labs there were concerns about (please search this forum to find the information).

I'm wondering why you've blanked out the photos of the gemstones and the sizes? This is a bit strange.

That's fine with me

As I said, I'll let them be blank until I get the gemstones back. I will only remove the black, so people can see that it's the same reports. I will also post both before & after pictures. Trying to angle the gemstones in the same way as they were pictured in first, so it's easy to compare.

OOOOh another SLP Cert....

 

[JewelryLover]

OOOOh another SLP Cert....

I suppose that's considered a bad thing, at least for you ... I'll keep that in mind for the future!

 

[chrono]

The only reports I trust their verification on are AGL and AIGS too. There is very strong suspicion from lapidaries and trustworthy dealers in Thailand that SLP does not actually exist. The skill and equipment on the other smaller and less known labs are also suspect, plus if the report number cannot be verified with the lab, they can easily be forged, as Gubelin recently sent out an alert on some unscrupulous people forging Gubelin memos.

I'll keep that in mind as well! The ebay store I purchased the SLP sapphire from I think ONLY use SLP reports and nothing else. I dont know the store I purchased it in, but I remember the name of their other ebay store "precioussiam2010". Same owner.

 

[ChrisA222]

I would be OK with an Emil report...at least last time I checked they had a website, and I think they are based in Japan? Could be completely incorrect, as it was a while ago that I had bought a stone with an Emil report and did a little looking around.

The SLP cert isn't worth 2 cents, again, my opinion.

I just found this, as far as Emil goes:

http://www.emil.co.th/index.php?mo=59&action=page&id=86934

 

[chrono]

The PS community is well aware of that company and the lab used. This certainly calls into question why they use the lab and only that lab, does it not? At least one PSer had a SLP verified sapphire sent to a different lab (can't recall if it is AGL or AIGS) but it came back as heated and diffused. This is a huge red flag to me. This is why detecting treatment in sapphires should only be verified by GIA, AGL and if pressed, AIGS and no other lab.

 

[JewelryLover]

I can also let everyone know that I got a list of Thai sellers at ebay that got plenty of different ebay stores under different names. I know the persons and/or companies they are registered to. So if someone wants to know I will be more than happy to post it. Some stores with the same owner/sellers have like 80% feedback vs. 100% feedback. Many use one for dishonest businesses while keeping their other account good and clean. There are also some sellers that have plenty of accounts with all accounts at 100% positive feedback.

The reason I know this is only because some diamonds are switched from store to store, over and over again. And another (most despitefull seller on ebay) got customer information about me that only another store got where I had to leave Negative Feedback.

We actually have experience of most of them and know who owns what. If you do too, I'm wondering why you buy from a store that only has SLP reports?

As far as EMIL is concerned - there was a debate about them some time ago. I have a report from them for a Ruby that looks incredibly dodgy. I don't know whether to trust it or not.

Please explain why you haven't shown the complete reports? It doesn't make any sense at all! In any event, the photos won't tell us anything because photos on these reports can be incredibly deceptive. The only way we can assess how good/bad your experiment has been is if you post photos you've taken of the gems (not the reports) before sending off. Then you can take photos of them using the same lighting conditions etc., when they come back.

Also, where are the other reports for the others? Will you be able to post them too?

I didn't actually know the truth about SLP, I didn't know they were untrustable. That's the only reason, but I've only purchased 1 gemstone at their shop.

I got pictures of them as well, not only at the reports. I think I posted 6 reports, they were locked up in the safe. But the 3 other ones weren't, but yes, I will find them within couple of days and post them!

I'm curious to see the results. When will they be back.

The PS community is well aware of that company and the lab used. This certainly calls into question why they use the lab and only that lab, does it not? At least one PSer had a SLP verified sapphire sent to a different lab (can't recall if it is AGL or AIGS) but it came back as heated and diffused. This is a huge red flag to me. This is why detecting treatment in sapphires should only be verified by GIA, AGL and if pressed, AIGS and no other lab.

Oooh very interesting. Not that I would have trusted that lab or even bought an expensive stone on Ebay ( never even heard of SLP), but does anyone have a link to that post. Who did they buy it from?

Lets just say everything works out exactly as planned. Looking over the numbers, this may be difficult to make any money.

Assume you were able to buy a sapphire for the price you stated of $100 per ct. So take a 2 ct stone. You pay:

$200 for the stone
$10 to ship from Asia?
$5 to ship to AGL for testing to confirm it's not heated
$55 for AGL Brief
$20 for AGL to ship back to you (They always us Registered mail)

You now have invested $290 in the stone.

You ship to your burner

$5 shipping
$10 burn fee
$10 ship back to you.

You now have $315 in the stone.

Back to AGL

$5 shipping
$55 AGL report
$20 Shipping back to you

You now have $395 in the stone.

You have to now sell it, and make a profit. You need a minimum of $500 just to cover your costs and time running back and forth to the post office. So the question is, can you now sell this heated sapphire for $500 or more.
