Hot laser inscription can penetrate a diamond's girdle and therefore alter the clarity grade of a diamond AFTER CERTIFICATION therefore voiding the actual certificate grading.Read more here about : The Photoscribe Laser Inscription Guarantee.There has recently been misrepresentation of the difference between hot and cold laser technologies used for diamond inscription. We would like to clarify the facts of the technologies. "Hot" lasers can and do fracture diamonds."Cold" lasers do not. "Hot" lasers can penetrate diamonds causing inclusions and blowing existing inclusions close to the surface."Cold" lasers do not. Hot and Cold lasers are technologically two very different types of lasers. Technically, there are many reasons the cold laser technology is far superior to hot lasers for diamond inscription. However, all reasons lead to the single most important point for you and your customers to understand. Unlike hot lasers, cold lasers are 100% safe for diamonds and will not chip or fracture your stones. GIA, AGS, EGL and HRD and all other major labs around the world all use PhotoScribe lasers.DCLA in Australia also uses the PhotoScribe cold laser technology. Photoscribe is so confident in the cold laser technology that they use, that they will guarantee, in writing, that their laser inscription will not chip or fracture your diamond. Ask others to offer the same written guarantee that Photoscribe offer and you will see that only the cold laser technology is 100% safe for the inscription of polished diamonds. Meanwhile in Australia....Damaged " Eternity " Diamonds by hot laser inscription |

Chaim,
Re: " Certifraud -Japan "
Your story already stated the obvious. I do not disagree.
Any damage, if any, done to the already fragile reputation of the polished diamond business will be judged by the public consumer in due course.
However considering GAAJ-ZENHOKYO is part of the dysfunctional Laboratory Manual Harmonization Committee (LMHC) I was disappointed that you overlooked the nomenclature implications of the useless LMHC of which GAAJ-ZENHOKYO is a LMHC member.
I find the existence of the LMHC more scandalous. Another example of an old boys club covering up for each other with a feigned facade of respectabilty.
In addition its a paradox how all seven members of the LMHC, one of which the AGTA does not have a lab anymore, collude together as a weak unified force but claiming to be all independent of each other as professional gemstone grading organisations?
* How can a gemstone grading laboratory claim to be an independent grader when seven gemstone laboratories all conform and collude together by " harmonizing " ?
The LMHC has no address, no website no phone number no bylaws they are a nonentity...just a front for the AGTA to hide behind due to it's ridiculous endorsment of treated gems that sold for millions on American television. See Direct Shopping Network (DSN) Andesine Class Action V Robert James International School of Gemology.
* How can a gemstone grading laboratory claim to be an independent grader when seven gemstone laboratories all conform and collude together by " harmonizing " ?
" The American Gem Trade Association ( AGTA ) controls certifications and collects fees for providing them. In 2005, the AGTA and other defendants collectively decided to redefine term of Paraiba stones to include all cuprous elbaites regardless of place of origin. The AGTA used its power in the jewelry business as the final arbiter regarding the qualifications and certification of gemstones to widely disseminate the false information regarding the redefinition of Paraiba stones." " The LMHC is a group of seven of the world’s largest gemological laboratories [ AGTA-Gemological Testing Center (USA), CISGEM (Italy), GAAJ Laboratory (Japan), GIA-Gem Trade Laboratory (USA), GITGemTesting Laboratory (Thailand), Gübelin Gem Lab (Switzerland), SSEF Swiss Gemmological Institute (Switzerland), the LMHC (Laboratory Manual Harmonization Committee) ] who got together and unilaterally decided that they could use the Paraiba name any way they decided. " : Robert James FGA, GG President, International School of Gemology
The whole diamond grading fiasco goes a lot deeper than just GAAJ-ZENHOKYO ....the LMHC connection can not be ignored. |

In reply to this week's Memo by Chaim titled " GIA's Indian Papers " 25th February 2010 : " The rumor mill about the quality of GIA India certificates started almost from the very moment that the diamond-grading lab in Mumbai opened " "http://www.idexonline.com/portal_FullEditorial.asp Since GIA's failure to name the GIA bribers during the Certifigate fiasco is it any wonder that rumours are rife about GIA grading reports ? GIA has itself only to blame for not bringing closure to this issue. However my main concern is the actual accuracy of colour grading and clarity grading. There are inconsistencies. Since the advent of so many online diamond vendors, GIA grading reports have become regarded as the " internet certificate ". Many of these diamonds are the ones rejected by dealers and palmed off on the internet... the "seconds "...the ones that have fallen throught the net and especially in Hong Kong then dumped elsewhere. In Australia I often lose sales when a client insists GIA grading reports are checked again by the International Diamond Council diamond grading laboratory the Diamond Certification Laboratory of Australia ( DCLA ) of which HRD is also a member. It's a telling sign in itself when clients want to be reassured by questioning GIA grading reports. It seems more often than not, most GIA diamond colour grades in particular are one colour better than the DCLA or HRD colour grades. Often fluorescence is an issue. An E colour with medium blue flurorescence often becomes a GIA D colour. I have proved this to myself again and again.It's an easy way to make money without breaking the rules but not exactly ethical and not helpful if GIA is to be respected for it's integrity. However whenever I purchase a GIA graded D colour diamond under one carat from and Indian source, diamonds are often genuine E colours upon rechecking at the DCLA. There is a Laboratory Manual Harmonization Committee of which most of the leading diamond grading labs are members. Different diamond grading labs have their own grading parameters. Why can not a uniform international standard be applied to colour grading amongst all these organisations ? What is the purpose of the LMHC ? My potential clients immediately lose confidence at these discrepancies especially when they are told ad nauseum that GIA is so well respected in addition to comparing other graded diamonds from other diamond labs. To summarize, both vendor and buyer are disappointed. Where is the consumer protection ? GIA needs to lift their game if they are to be respected and trusted if they keep insisting they are " the foremost authority in gemology " Daniel F Katz GG www.DiamondImports.com.au |

In regard to Obert Mpofu : What is mined is your's and what is your's is mine ! China seems to be the the catalyst here unashamedly exploiting the resources for the benefit of the Zimbabwean elite showing no care for their own people. Is this what diamonds do for poor people ? What chance have the World Diamond Council to monitor conflict diamonds from Zimbabwe when dealing with a Zimbabwean minister that ignores his country's judiciary in fear of his country's army constant threat while China remains the beneficiary at the expense of the indigenous population ? It is time the World Diamond Council and the World Federation of Diamond Bourses starts putting more pressure on members of the Shanghai Diamond Exchange and stop pretending SDEx is not part of the equation. |

| Boyajian's milk of amnesia for those who can still remember the GIA grading report bribery scandal over which Boyajian presided at GIA, confirms there must be commercial pressure on all labs to upgrade marginal stones or lose business to other labs who are prepared to reduce standards. AGS states " The AGS Laboratories, created in 1996, is committed to protecting the consumer by providing unbiased reports based on the highest standards of diamond grading." So why in hell's name would AGS want to be remotely associated with Boyajian ? It's laughable but still an annoying reminder to those of us who know better. The apathy of the jewellery industry has only itself to blame for the harm to it's fragile reputation by it's continued silence and not letting AGS know your objections to this ridiculous situation of Boyajian's ressurrection. We have removed all AGS logos and AGS graded diamonds from our website.It is just too embarrassing. Daniel F Katz GG www.DiamondImports.com.au

Dear Mr. Even-Zohar,You've published a very "to-the-point" (as they always are!) article in DIB Online this week [ http://www.diamondintelligence.com/magazine/magazine.aspx?id=7149 ], and it hits a general issue of the industry's disregard for reputation at the wholesale level. The lack of accountability of wholesalers to live up to their commitments has been severe, at all stages of the pipeline. I understand that your article is about management living up to its "rhetoric", but my point below is slightly more aimed at the fundamentals of our industry's reputation.Forget retailers and producers, its the traders and manufacturers in the polished diamonds section of the pipeline that have initiated/allowed the complete disregard for financial ratios and commitments in our business, by extending long unsecured credit terms, and thereby allowing late payers to survive in the business. What surprises us the most, is that most of the polished trade believes it is their right/duty to pay late, because "their client is paying them late..." Of course, nobody is ready to compensate (late payment interest, etc) for their "breaches of commitment". They simply take their business elsewhere. Maybe its not up to the producers, but the Bourses to do step up and encourage Best Practices, or other bodies like the newly created CJRP, etc.Regards,Sachiv R. MehtaManaging DirectorSupergems NVWhere Trust is a Tradition |

I guess since I'm a "Baby Boomer"(63) ,I'm NOT too well versed in these new millenium cybernetically inclined "Internet" procedures, and there is No Way N' Hell that I can find a Rough Diamond Grading School in our old US of A. Can anybody recomend one? e/mail me:uncleben1146@yahoo.com Thank You all, and Merry Christmas. |
