========[ Invite a Friend - http://www.ganoksin.com/invite.htm ]======== Judy, Ron, and all, Well, since you asked.... Judy is correct in remembering that I have written about this very topic. I did an article on jewelry quality that was published in August, 1999, in AJM, and on plating quality control in AJM in May 2000. I also produced a fair amount of consumer-oriented info (with the help of Orchid members) for Blue Nile for their website, although the company actually used very little of it. As for a quality rating system, the topic has been discussed again and again at MJSA over the last 10 years, and probably longer than that. Committees have been formed, proposals discussed, and as far as I know, that's sort of been the end of it. When push has come to shove, there hasn't been enough consensus or financial support to actually launch a quality-marking program. The first problem, of course, is deciding what constitutes "good quality." What for one person is barely adequate, for another is quite good. The extremes aren't hard to define -- most folks can agree on extremely fine quality, and on very, very poor quality. The problem is so much product falls somewhere in the middle. Where do you draw the line? For example, Ron mentions testing chains for strength. This is very feasible -- in fact, several papers have been presented at the Santa Fe Symposium discussing methods for doing just this. The tricky part in developing a quality mark is, how strong is strong enough? Do I need a chain that can support 60 lbs., or is 40 lbs. good enough? Is the chain that supports 60 lbs. inherently better than the one that supports 40 lbs.? And which test do you use? Some chains will perform better under some test conditions, and worse under other test conditions. This type of testing is also destructive, so is not suitable for one-off products. (As far as I know, chain strength can only be determined by breaking the chain.) Gathering this sort of "performance" data is certainly feasible, at least in theory. Chris Corti of World Gold Council in London has done some interesting work in this area: he presented it at Santa Fe probably five years ago, if anyone is interested in looking it up. With X-Ray fluorescence, you can test for underkarating (JVC already provides this service, with support from MJSA, although I'm not sure how many people are using it.) X-Ray fluorescence can also be used to test for plating thickness. Ring shanks can be measured, and information on how much pressure it takes to bend it can be obtained from physical testing or determined mathematically. Visual inspection can be relied upon to evaluate whether stones have been set straight, whether solder seams have been done correctly, etc. One difficulty comes in explaining to the customer what this objective data means. For example, would the consumer really find it helpful to know that this chain suppports 100 lbs., while this chain supports 30 lbs.? I think you'd have to offer some translation, i.e., you need a chain that has xxx tensile strength so the baby can't break it, but you don't want it to support more than xxx lbs. because that would allow you to be strangled by the chain if it caught on something. In the jewelry industry, such explanations have normally been left up to the retailer, upon whom the bulk of consumer education traditionally falls. And look how that has turned out: there *is* a grading system for diamonds, with clearly defined quality standards and lots of information available to the consumer, and yet plenty of poor quality diamonds are sold by retailers who assure uninformed consumers that an I3 is a diamond offering beauty and good value. (And maybe for some customers it is, as long as it is priced appropriately. But that's an argument for another day.) Having more objective data about jewelry performance available to the consumer would doubtless be a good thing. But it would cost money. Someone has to test the materials. Someone has to write up the results. Someone has to publish the results. Someone has to market the product and get people to pay for it. Someone has to pay the lawyers to defend the publisher when the inevitable lawsuits pop up. (When you name names and say something is poor quality, you're going to get sued eventually, at least in this lawsuit-happy country. And yes, Consumer Reports does get sued periodically by unhappy manufacturers.) So how do you pay for all this? You can't pay for it with advertising, lest you introduce bias into the system. Who knows how many customers there are willing to pay $100 or more a year to learn how a particular company's jewelry measures up? (I would guess the number is significantly below the 100,000 mark.) So far, manufacturers haven't gotten excited about pitching in a couple grand a year to pay for it. Another hurdle: jewelry is frequently not a branded item. When I walk into Zales, I don't know who made which pieces. And unless I know Chain Y came from Manufacturer X, I can't apply the data, even if it were made available. You certainly couldn't just label it "chains from Zales." Those chains might come from a dozen different manufacturers, some acceptable quality, some less good. If I'm Good Quality Manufacturer who happens to sell chain to Zales, and you test Poor Quality Manufacturers chain and give "Zales' chains" an "F" you better believe I'm going to be on the phone to my lawyer in the morning. A general-information book is probably more realistically feasible. I'd love to write such a thing: I just have to find someone interested in paying me to do it. :-) There are similar things already out theRe: I have several guides to buying colored stones, estate jewelry, etc. So it's still a matter of leading the horse to water. Well, anyway, that's my two cents worth. Aren't you glad you asked?
