Versions of The Order of the Golden Fleece Origin of the Order • The Order of the Golden Fleece was established on 10 January 1430, by Philip the Good, Duke of Burgundy, in celebration of the prosperous and wealthy domains united in his person that ran from Flanders to Switzerland. It is restricted to a limited number of knights, initially 24 but increased to 30 in 1433, and 50 in 1516, plus the sovereign. • "for the reverence of God and the maintenance of our Christian Faith, and to honor and exalt the noble order of knighthood, and also ...to do honor to old knights; ...so that those who are at present still capable and strong of body and do each day the deeds pertaining to chivalry shall have cause to continue from good to better; and .. so that those knights and gentlemen who shall see worn the order ... should honor those who wear it, and be encouraged to employ themselves in noble deeds..." The Order continues today • In 2015, one day before the Princess of Asturias's birthday, she was granted the Order of the Golden Fleece. Leonor, Princess of Asturias Spain • Questions? .

  • The Wittelsbach-Graff and Hope Diamonds: Not Cut from the Same Rough
    THE WITTELSBACH-GRAFF AND HOPE DIAMONDS: NOT CUT FROM THE SAME ROUGH Eloïse Gaillou, Wuyi Wang, Jeffrey E. Post, John M. King, James E. Butler, Alan T. Collins, and Thomas M. Moses Two historic blue diamonds, the Hope and the Wittelsbach-Graff, appeared together for the first time at the Smithsonian Institution in 2010. Both diamonds were apparently purchased in India in the 17th century and later belonged to European royalty. In addition to the parallels in their histo- ries, their comparable color and bright, long-lasting orange-red phosphorescence have led to speculation that these two diamonds might have come from the same piece of rough. Although the diamonds are similar spectroscopically, their dislocation patterns observed with the DiamondView differ in scale and texture, and they do not show the same internal strain features. The results indicate that the two diamonds did not originate from the same crystal, though they likely experienced similar geologic histories. he earliest records of the famous Hope and Adornment (Toison d’Or de la Parure de Couleur) in Wittelsbach-Graff diamonds (figure 1) show 1749, but was stolen in 1792 during the French T them in the possession of prominent Revolution.

  • Renowned for His Iconic Designs and Breathtaking Gem Collections, Harry Winston Was a Man Who Knew the True Value of a Diamond
    A BRILLIANT LEGACY Renowned for his iconic designs and breathtaking gem collections, Harry Winston was a man who knew the true value of a diamond. BY ALLISON HATA 54 A diamond is anything but just another stone. Highly coveted, precious and exceedingly rare, diamonds can take on different meanings: a symbol of status, a statement of love or a sign of purity. “Diamonds are a physical connection to [the earth] other than our feet on the ground,” says Russell Shor, a senior industry analyst for the Gemologist Institute of America. “When the earth was young and there was volcanic mass seething inside—this is how diamonds were formed. Diamonds connect us to that.” One man understood this intrinsic connection and dedicated his life to bringing the world closer to the precious gem through his jewelry designs and generous gifts to national institu- tions. Known as the “king of dia- monds,” the late Harry Winston was the first American jeweler to own and cut some of the most iconic stones in history, in addi- tion to setting a new standard for jewelry that showcases a gem’s natural beauty. Born more than a century ago, the young Winston—the son of a small jewelry shop owner—demonstrated a natural instinct for examining diamonds and precious gems. In subsequent years, he cultivated this talent to become one of the most prominent diamond merchants and designers of his time. His legacy lives on through the house of Harry Winston, which pairs his classic vision with a contemporary sensi- bility to create modern pieces that still grace the red carpet today.

  • Star of the South: a Historic 128 Ct Diamond
    STAR OF THE SOUTH: A HISTORIC 128 CT DIAMOND By Christopher P. Smith and George Bosshart The Star of the South is one of the world’s most famous diamonds. Discovered in 1853, it became the first Brazilian diamond to receive international acclaim. This article presents the first complete gemological characterization of this historic 128.48 ct diamond. The clarity grade was deter- mined to be VS2 and the color grade, Fancy Light pinkish brown. Overall, the gemological and spectroscopic characteristics of this nominal type IIa diamond—including graining and strain pat- terns, UV-Vis-NIR and mid- to near-infrared absorption spectra, and Raman photolumines- cence—are consistent with those of other natural type IIa diamonds of similar color. arely do gemological laboratories have the from approximately 1730 to 1870, during which opportunity to perform and publish a full ana- time Brazil was the world’s principal source of dia- Rlytical study of historic diamonds or colored mond.

A little information about topics such as formation, sources, mining, or cutting can often help, too. In every pre- sentation, however, it’s essential to identify and reinforce the factors that make diamonds valuable and important – in other words, truly precious – to each customer. After all, purchase decisions involve the head, but the desire to own or give a diamond almost always springs from the heart. That’s the realm of magic and romance. The emotional meanings of diamonds have many origins and they have evolved over thou- sands of years. Diamond’s unique beauty and remarkable properties have helped create some of the deepest meanings. Others have come from cultural traditions, the glamour of celebrities, and the events of individual lives.

  • Record Setters Rarity, Provenance and Authenticity, Along with Global Economic Conditions, Are Driving Record Prices at Auction
    Record Setters Rarity, provenance and authenticity, along with global economic conditions, are driving record prices at auction. BY Ettagale Blauer February 2012 It seems record-breaking prices have become the norm at every major jewelry auction, but a look back shows that the highest prices paid for certain gems and jewels were set more than 20 years ago. That these records have held up is all the more remarkable considering the tremendous increase in appreciation for rare and fine, unique gems and jewels in recent years. The potential audience for these treasures is dramatically more global than it was barely a quarter-century ago. This is partly due to the sophisticated and aggressive marketing by the top auction houses, but also to the new wealth being amassed in parts of the world that were not even on the radar until recently. Stir in a limited number of available pieces and records are bound to be set. While rarity, provenance and authenticity are the usual hallmarks behind record-setting results, economic conditions can play just as big a role.
