Ancient Gem-Studded Teeth Show Skill of Early Dentists
http://news.nationalgeographic.com/news/2009/05/090518-jeweled-teeth-picture.html
Ancient peoples of southern North America went to "dentists"—among the earliest known—to beautify their chompers with notches, grooves, and semiprecious gems, according to a recent analysis of thousands of teeth examined from collections in Mexico's National Institute of Anthropology and History.

Random Thoughts
Crooks, scandals, and scalawags are good. Con artists of all forms offer us a sort of perverse education. They are a key ingredient to avoiding stagnation and achieving a constantly evolving Wall Street, for without them we would never learn the often-costly lessons of excessive greed and blind trust that prompt change and reform. In the way a child learns not to touch a red-hot stovetop, the stock market has learned—sometimes over and over again—to be skeptical of just-too-good-to-be-true investment opportunities and the people promoting them. Because the root of all swindles, greed, is inherent to human nature, Wall Street will never lack for its share of con artists and con games, regardless of what drastic measures Washington might think it's taking. So, rather than condemn such swindlers, we can easily learn from their stories.

At first it was hard to believe, but if EITI could persuade companies to publish what they pay and for governments to disclose what they receive, then I must say it's a success. Hats off to the initiative!

How Shoppers Make Decisions In Recession
http://www.time.com/time/business/article/0,8599,1899035,00.html
Companies will start to play a mind game with consumers that is slightly different from what we've seen in the past. Some companies assume that the consumer doesn't have any money. But now they're learning that that's not the case. Consumers still do have money — at least many do — but the reason that they're not spending it is because they're afraid they may lose the money in the future.

Well, let me put it this way. Anyone who's ridden a horse knows that the secret of success is to have the horse think that it's doing what it wants. So, I think that when people feel like somebody else is telling them what to do, there's going to be resistance. If they think it's what they themselves want, then they sign right up. Lao Tzu said this 2,500 years ago: When the best leader leads, the people say we did it ourselves.

Kikunoi
The Art You Can Eat
http://online.wsj.com/article/SB124242719429025155.html
After spending three days in Kyoto, where visitors can eat variations of kaiseki for breakfast, lunch and dinner, I began to see why this centuries-old cuisine holds so much fascination for the most inventive chefs of Europe and America. Kaiseki is a tonic to the senses from every direction, and something no Western restaurant I've ever dined can approach. It demands perfection from the freshness and preparation of the ingredients to the dishes they are served on. The noise in some New York restaurants makes it impossible to concentrate on your meal; kaiseki diners sit in a tranquil, private room and gaze onto a Japanese garden while polite, efficient waitresses in kimonos cater to every need. The cost, at Kikunoi, is $150 a person -- a bargain compared with, say, the $275 tasting menu at Thomas Keller's Per Se in New York.

A kaiseki dinner at Kikunoi is an experience visitors won't quickly forget. The simplicity of a kaiseki dinner masks its complexity. A must visit, really.
http://online.wsj.com/article/SB124242719429025155.html
After spending three days in Kyoto, where visitors can eat variations of kaiseki for breakfast, lunch and dinner, I began to see why this centuries-old cuisine holds so much fascination for the most inventive chefs of Europe and America. Kaiseki is a tonic to the senses from every direction, and something no Western restaurant I've ever dined can approach. It demands perfection from the freshness and preparation of the ingredients to the dishes they are served on. The noise in some New York restaurants makes it impossible to concentrate on your meal; kaiseki diners sit in a tranquil, private room and gaze onto a Japanese garden while polite, efficient waitresses in kimonos cater to every need. The cost, at Kikunoi, is $150 a person -- a bargain compared with, say, the $275 tasting menu at Thomas Keller's Per Se in New York.

Diamond Market Update
De Beers woos safe-haven investors

Diamonds are of limited interest to a lot of people because of the difficulty in buying and selling. Gold remains the ultimate hedge.

According to Brock Salier, a mining analyst at Ambrian, diamonds represent a much riskier investment than gold. Unlike the yellow metal the stones, traded through auctions and private tenders, have no public market price and there is no instrument investors can use to hedge against fluctuations. I think he was spot on.

The fall 2009 palette is more unique and thoughtful than the typical autumnal hues of years past.

It's fascinating, really.

Color Grading Diamonds
- Color Grading D-To-Z Diamonds At GIA
http://www.diamonds.net/news/NewsItem.aspx?ArticleID=26332
- Color Grading Diamonds At GIA: The First Fifty Years
http://www.diamonds.net/news/NewsItem.aspx?ArticleID=26331
- GIA Master Stones: Only Precision Will Do
http://www.diamonds.net/news/NewsItem.aspx?ArticleID=26330
- Today, GIA uses 'working master sets' of 10 stones to grade the most commonly submitted diamonds, which fall between D and N. Starting with O, the lab doubles up, with one stone per two-grade range, from O-P down to Y-Z. The GIA Laboratory also, however, uses a face-up Z master at the lowest end of that color range to delineate the border between the D-to-Z scale and the start of the fancy-color scale. Because dirt can accumulate on diamonds and affect their appearance, GIA “boils” each master set in sulfuric acid every two to four weeks. The authors reported that some master sets submitted to GIA for review had their color altered by as many as four grades because of dirt that had accumulated on their bruted girdles. To avoid abrasions and chips that can also affect color appearance, GIA lab graders use rubber-tipped tweezers to handle all master stones.
- Now for the human element. Staff members must pass a number of color vision tests and then successfully complete several weeks of training before they are accepted as color graders. Because different individuals can have different color perceptions — a critical concern given the extremely fine borders between color grades — all diamonds receive a minimum of two agreeing opinions before a color grade is assigned. Some stones require more opinions. For example, larger and potentially D-color diamonds are assigned to the most experienced graders. All color graders must take an hour-long break from color grading after every hour of grading to minimize eye fatigue. Round brilliants are viewed table-down on a white tray with master stones in the E to N range — since most of the diamonds graded range from D to M. The grader typically rocks the tray containing the masters and the client stone to eliminate distracting reflections. Fancy shapes at the lower end of the color scale are observed both table-up and table-down, then averaged to reach the overall grade. Potentially fancy-color stones are graded face-up at Z. Rather than attempting to match the diamond to a single master stone, GIA brackets the diamond between two masters, allowing the grader to quickly narrow the potential grade. Once the most appropriate master stone has been determined, the grader observes the diamond on both sides of that master — but never touching it — because the left eye and the right eye may perceive depth of color differently. Fancy shapes are more difficult to grade because they can show different amounts of color depending on viewing angle. GIA has found that the best average color is observed when the stone is viewed face-down with its long axis at a 45-degree angle to the grader, close to the master stone but without any overlap. In this position, it exhibits neither the most intense color nor the washed-out areas.
Great review. Thanks to GIA.

GIA has found that the best average color is observed when the stone is viewed face-down with its long axis at a 45-degree angle to the grader, close to the master stone but without any overlap. In this position, it exhibits neither the most intense color nor the washed-out areas.
Great review. Thanks to GIA.
