[⚠️ Suspicious Content] The Amsterdam diamond is a 33.74-carat, pear-shaped, fancy-black diamond, with a total of 145 facets. For black diamonds only 3Cs of diamond characteritics are relevant :- Color, Cut and Carat weight. The Clarity of the diamond is not relevant as black diamonds are opaque. Black diamonds do not reflect or refract light, properties responsible for the production of brilliance and "fire" in conventionl diamonds. Yet, most black diamonds possess an "adamantine" luster, which in the case of the Amsterdam Diamond is remarkble and unique, and seldom seen in other large black diamonds. A standard pear-shaped diamond has 57/58 facets. However, the Amsterdam diamond has more than doube this number. The number of facets appears to have been deliberately increased, perhaps to enhance the "adamantine" luster of the diamond. It is the second black diamond of significance to make it's appearance in the diamond trade after the Black Orlov diamond; a diamond purported to have originated in India, but whose first authentic appearance was around 1950, when Charles F. Winson, the New York City, gem and jewelry dealer, acquired the diamond. In the list of famous black diamonds the Amsterdam diamond occupies the 7th position. See table below.
التاريخ
The Amsterdam diamond gets its name from the city of Amsterdam, an international power house of the diamond industry, where the rare black diamond made it's first appearance in 1973, at the jewelry store of D. Drukker & Zn. The rough diamond, perhaps the only black diamond discovered in South Africa, was purchased by the Amsterdam based company, D. Drukker & Son in 1972, who got the diamond cut and polished by expert diamond cutters of their own company. When the rough stone was eventually transformed into the 33.74-carat, pear-shaped black beauty, with a luster of its own despite its opacity, the owners of the diamond, decided to Christen it "The Amsterdam Diamond" in honor of the 700th anniversary of the City of Amsterdam, that had once flourished as an important diamond cutting and trading center in the world, particularly when the Dutch East India Company was in control of the diamond producing areas of the Indonesian Archipelago in the 17th-century, and subsequently after the discovery of diamonds in Brazil in the early 18th-century, and in South Africa in 1867. After World War II, Amsterdam lost its pre-eminent position as the main diamond cutting center in Europe and the rest of the world. This unfortunate situation was precipitated by the deportation of tens of thousands of Amsterdam Jews, including over 2,000 diamond cutters, who died in Hitler's concentration camps during the holocaust. After World War II, Antwerp in Belgium became the main diamond cutting center of Europe.[2]
The diamond is named after the city of Amsterdam, Netherlands, where it was sold at auction in 2001. The auction highlighted its rarity, and it fetched a high price due to its size, color, and unique characteristics.
