Interesting Johan.
2. As you can see on Marty Haske's website, GIA apparently now have some UV light in the color grading lamps they use - it is possible a strong blue stone will get a higher grade in such a case.
The change in grade will depend on the bulb and the grading technique
3. GIA (I believe) claim there is some UV light in almost all viewing environ's, so they should grade in some UV. This is a strong case.
It is a case that turns around 50 years of grading standards, makes the DeBeers stockpile more valuable, and foster's what I think is a consumer deception. It only benefits certain elements of the trade. Your Chevy is now a Cadillac, do you understand, and would you accept that.
3. Therefore should we all, or should we not, grade with the same lamps?
My opinion is well documented.
4. Personally I do not believe in using other than the cheapest daylight fluoro tubes from any hardware store. I have tested many and these seem to enable easier differentiation between the subtle grades we are interested in.
Remind me not to buy a stone you have graded![]()
High color temp tubes seem to make every thing look closer to the same.------
???? Comeon Gary I disagree with you here. Higher color temperature bulbs put more energy below 500nm where the relative absorption features distinquish between diamonds. Lower color diamonds absorb more in the blue. If you have no energy in the blue green (below 500nm), i.e. grade with a yellow light, then I believe that you can't see any differentiation between stones.

The appraisl business is a different task; it must support high retail asking prices, just as the Rap list supports high wholesale priceing.
The appraisal business should support facts of the marketplace, not inflated ficticious "retail values". It is not that difficult to look at reality, although some in the business make a very good living pandering to the trade and deceiving the overly gullible consumer.

Before you spout theory Marty, go buy a few different tubes and check ot the differences in practice.
Well, At least I'm not spouting BSAll D65 bulbs are not the same, period, I believe looked at a few more bulbs' spectra than you have![]()
You may have heard of the diffference between looking and 'looking good'.
Yah, marketers, who are all sizzle and no steak
Re 50 years - before that we had 50 years where fluoro diamonds were more highly prized. I think that was a wrnog decision - they hit the blue white problem with a sledge hammer.
OK, so you support consumer deception?
There are many people who really know diamonds who like a diamond to be medium to strong blue fluoro.
Yah, spoken like a true merchant, because they know they can buy fluor stones at a discount because they are probably overgraded, and tell people they have a "true D", rather than telling them the truth that they have a "new D", and being ficticiously price competative, am I giving you a deal, bend over please.

So the question is, can an appraiser actually challenge a GIA
certificate when the final judgment on a GIA color call is the GIA
itself? (Johan @ MDX)

An appraiser is rendering his opinion as to what he believes the grade to be, just as GIA is doing the same.
Let's say for example you send a stone to AGS that was formerly graded by GIA. AGS doesn't bother to check and see how GIA graded it, but instead stands confident on their own opinion and grades it as they see it.
Independent labs and independent appraisers essentially operate in a 'checks and balances' capacity in the diamond grading industry, just as the judicial and legislative systems of the US government operate in a 'checks and balances' capacity in the legal system, each making sure the other doesn't run amuck.
If the GIA was the 'final judgement' on the grading issued on their own reports (or others), then you would essentially have an unacceptable situation of totalitarian authority and dictatorial control.
A more democratic method which could be used if 'final judgement' were required would be to have three recognized top laboratories grade a diamond, with an agreement of two or more establishing the 'final' grade.

The laboratories and the Appraisers are equally important to our industry but the lack of exact standards is a real nightmare.

Hello adamasgem,
I am impressed by what you've posted. I am not in the trade/field but as a layman, it seems that you know exactly what you're talking about and you have reasonable grouds for your arguement. Also, what you posted remains the few in this forum which are different from the rest of the GIA/AGS fan-club/others.
I have one question regarding this topic. What is your view on GIA and IGI-the two major labs?
Thanks for the compliment. As to strictness in grading standards, I believe AGS, GIA grading and then the other majors in that order. If a "lab" writes "values" for pre consumer purchase feel-good purposes, then I think those retailers who purchase them and those write those "sales tools" may be suspect as to their "independence" and due diligence.
Ask yourself why the consumer is always getting such a deal compared to the "values" stated on such paper. Am I (the retailer) going to sell you $10 bills for $5?
Thankfully, neither AGS nor GIA have or will venture into "valuations" like some of the "independent" labs whose "paper" is used to tell the consumer what a "great deal" they are getting. (Bend over consumer, in most cases)

Anyway, outside USA, in my experiance, GIA does not have as good reputation for consistency as IGI for grading diamonds.
Consistency and accuracy are two different things![]()
Re the appraisal issues - it is not my area - and I am not happy that our trade stoops to marked up and marked down prices, but then that is lafe, especially in the mid to lower market levels. ----------------
Gary, If you are not happy about it then take a stand regarding those who facilitate the practice

IN YOUR CORNER
Before you buy, study diamonds or pay the price
By PAUL WENSKE
Columnist
But prices can vary dramatically. A top-quality one carat diamond can fetch $20,000. A one carat diamond just three grades lower in color may go for $900 or less.
This is really more than a little overblown, but what do you expect from journalists![]()
With diamond prices at a premium, ads that boast deep discounts on diamond bracelets and rings can seem better bargains than they really are.
Recently, a reader showed me a department store ad for a gold bracelet with 22 diamonds, total weight two carats. The bracelet sparkled in the ad, which touted a sale price of $299, down from the regular price of $436.
An accompanying appraisal estimated the bracelet's replacement value at more than $1,000.
Yup, bend over consumer
But wait! For one day only, starting at 9 a.m., the lucky consumer could buy the bracelet for $199 — a full $100 less than even the sale price.
Bargain of the century? Not really. A close reading of the appraisal explained why. The diamonds' clarity was graded I3 — or Included 3 — the lowest of 10 possible grades.
In essence, the diamonds were industrial grade, or as Holloway put it, “the dregs of the dregs.”
So were consumers who paid $199 or $299 for the diamond bracelets bilked? Probably not, Holloway said, because they paid close to the bracelet's true value.
My sincere appologies on your not taking a stand, Gary
But could consumers still have been misled? Possibly, if they were persuaded to buy the bracelets, thinking this was a deal too good to pass up.
It's a problem some jewelers say has plagued their industry. While misleading and deceptive pricing is illegal, it's hard to define, much less document.
If it walks like a duck...
The most blatant form is advertising a diamond's weight as two carats when it is only one.
That is called out and out fraud
Another form of deception that is harder to prove is called fictitious pricing. That occurs when jewelry is marked at a price higher than it would likely ever sell for, is carried for a short period of time at that price and then deeply discounted.
Yup, all too familiar theme, "regualarly priced"
The Federal Trade Commission requires a store to show that the higher referenced price is “bona fide.” That means the item has to be offered at the higher “regular” price for a substantial amount of time before the store can call the discounted price a sale price.
But what constitutes a legally bona fide price varies from state to state.
What most often happens, Holloway said, is that department stores buy diamond jewelry in bulk from foreign countries. In lots of 10,000 or more, quality can vary widely. Diamond appraisers may rate some of the items. But they can't rate all of them.
Appraisers can, but the s**t merchants are too cheap to have it done
High-quality jewelry might sell easily. But lower-quality items might sit around until stores slash prices or pass them off to close-out companies that peddle the rocks on infomercials on late-night TV.
Oh yah..
Holloway said consumers who want the best quality at the right price should take the time to be informed before forking out a lot of money for diamond jewelry. He offered these tips:
• Know that high-quality diamond jewelry is seldom sold at steeply discounted prices.
• Contrast prices of comparable diamond items at different stores, including Internet sites.
• Learn the basics. For example, diamonds are rated according to “the four Cs” of color, carat weight, clarity and cut.
• Buy only from a reputable dealer.
• Check out the store's policy on returning an item if you are not happy with it.
• Research diamond prices and retailers at Internet sites and Internet forums such as PriceScope.
• If possible, get the opinion of an independent accredited appraiser.
Great comments Gary, I might also add to pay with a credit card as there is much more leverage in getting your monies back if there is misrepresentation. Other than Ebay jewelery sales (consumers should REALLY watch their backside there), I haven't seen any real misrepresentations from most Internet dealers (there are maybe some exceptions). I've disagreed with some grading from time to time (mostly because of fluor, once on "eye visibility) , but I think, in general, those who sell higher quality goods on the Inet, are pretty straight forward and honest.
Anytime a consumer sees the 50% off sale at a retailer, they should
ask "50% off of what?".. I've seen manufacturer's tagged "prices" at 5X, what BS, and "appraisals" on Ebay similarly inflated..
As Gary said, proving the deception is difficult because of the lawyers at the paper mills..
