World Famous Jewelry Collectors

There are people who are really crazy about diamonds, rubies, and other gemstones. They buy jewelry from everywhere in the world, they get it heritably or somebody makes a gift for them. So who are they? Let's make it clear!

Queen Elizabeth II 

The first very famous jewelry collector is Queen Elizabeth II. She inherited her jewelry collection as a successor to the Crown and also from her father, King George VI, who presented a diamond and sapphire necklace and earrings, known as the Victorian Suite of Sapphire and Diamond set on her wedding day. In her spectacular private collection that is situated in the room below the Buckingham Palace are gathered the treasures of all times: the Timur Ruby, a 352 carat spinel inscribed with the names of the Mughal emperors who are considered to be its previous owners; cuts of the Cullinan diamond, the largest rough diamond ever found. The largest cuts of Cullinan Diamond decorate the Crown Jewels of the UK. Cullinan, I or 'Star of Africa' in the Head of Sovereign's Sceptre with Cross and the Cullinan II is on the Imperial State Crown. Queen Mary also gifted Queen Elizabeth a brooch which was made from Cullinan III and IV and according to rumors it was named 'Granny's chips' by Elizabeth the Queen.

Elizabeth Taylor

The other pretty woman who was in love with everything that sparkled is Elizabeth Taylor, the wife of Richard Burton and who wrote a book: Elizabeth Taylor “My Love Affair With Jewelry”. She collected a great amount of jewelry for her whole life. Her collection was sold at Christie's auction in New York in 2011 and attracted the world's attention. This collection included jewels from such famous brands as Bvlgari, David Webb, Cartier и Van Cleef & Arpels and was sold for $95.5 million. One of the most famous pieces of jewelry from her collection was the 16th-century pearl - La Peregrina. It was owned by Mary Tudor, the first Queen of England. Later the pearl became an element of Cartier’s diamond and ruby necklace which was sold for $9.6 million. Richard Burton made other treasury presents for Elizabeth, for example, an almost flawless emerald cut Krupp diamond ring, a Van Cleef & Arpels ruby and diamond ring of 8.24 carats, and also a 'perfect' red ruby that was gifted for her by the lovable husband on the Christmas Eve.

Sarah Frances Croker-Poole

If you married the Prince, you can also have your own diamond jewelry collection, just like Sarah Frances Croker-Poole. She was the fashion model and debutant before she married Prince Karim Aga Khan IV, the spiritual leader of Ismaili Muslims and one of the richest men in the world. When she became the Princess, she was immediately gifted with original jewelry pieces from Boucheron and Cartier. But we need to admit that this marriage didn’t last very long and after the couple divorced here came the question: to who belongs the jewelry collection of the Princess. Prince Karim assumed that the jewels had to stay with the Aga Khan family. But Sarah Frances wanted the pieces to be auctioned off in order for her to start a charitable foundation. The Princess won the court and all her treasures were auctioned through Christie's Geneva. The most expensive jewelry piece sold for $27 million was the Begum Blue, a blue heart-shaped diamond of 13.78 carats that was set in the center of a necklace with 41 smaller heart-shaped diamonds.

Wallis Simpson

Wallis Simpson is known not only as of the woman for whom King Edward disengaged from his throne, but also as a great jewelry collector of all times. During the 35-years marriage with Duke of Windsor she gained a spectacular amount of jewelry pieces among which there was Cartier charm bracelet with “handwritten” Prince’s engraving, a custom Van Cleef & Arpels ruby, and a diamond necklace (a gift on her 40th birthday) which was later sold for $2.5 million, a custom made Cartier diamond and onyx panther bracelet. They said that this bracelet was sold to Madonna for $5.7 million.

Lily Safra

Lily Safra, a widow of a billionaire banker, Brazilian philanthropist, and a passionate jewelry collector had a soft spot for the American jewelry designer Joel Arthur Rosenthal who found the fine jewelry house JAR in Paris. In 2012 she auctioned 18 pieces of this jewelry collection that turned out to be the largest quantity ever put up for auction. At the Jewels for Hope, auction lady Safra sold more than 70 jewelry pieces that included a 34.05 carat rectangular-cut diamond ring, a 32.08 carat cushion-cut Burmese ruby ​​adorning a Chaumet ring, and earrings that have 19 carat pear-cut diamond each. Auction proceeds reached almost $38.2 million and were given to charity in the name of The Lily Safra Foundation.

There are more famous and passionate diamond and gemstone jewelry collectors nowadays. And we would like to share the information about them in our next article. Just let us now if you like such facts about the treasury world?

    Static Balancing Machines Overview

    Static balancing machines play a critical role in the field of rotor balancing, ensuring optimal performance and longevity of various rotating equipment. Whether it’s rotors in industrial fans, crushers, or turbines, achieving precise balance is essential to mitigate vibration and enhance operational efficiency. This note provides an extensive overview of static balancing machines, emphasizing their importance, functionality, and applications.

    Understanding Static Balance

    Static balance refers to the condition where the center of gravity of a rotor aligns with its axis of rotation when it is stationary. An imbalance occurs when the heavy point of the rotor is offset from this center. This imbalance is primarily due to uneven mass distribution, which leads to one side of the rotor being weighted more than the other. Static balancing aims to correct this by strategically adding or removing mass from specific points on the rotor.

    Static Balancing Process

    The static balancing procedure involves several key steps:

    Initial Assessment: The rotor is first assessed to identify any apparent imbalance. This can be done using simple tools and techniques to locate the heavier side. Weight Adjustment: Once identified, adjustments are made by adding or removing weights from the rotor. The aim is to redistribute the mass evenly along the rotor. Verification: After adjustments, the rotor is tested again to ensure that it now maintains equilibrium when stationary.

    One of the most common applications of static balancing machines is with narrow disk-shaped rotors, where maintaining balance in a single plane is vital.

    Advantages of Using Static Balancing Machines

    Static balancing machines offer several advantages:

    Precision: They allow for accurate detection and correction of imbalances, reducing the risk of vibration that can lead to mechanical failures. Enhanced Equipment Lifespan: Proper balancing helps minimize wear and tear on bearings and other components, ultimately prolonging the life of the machinery. Increased Efficiency: Balanced rotors operate more efficiently, leading to lower energy consumption and better overall performance. Key Features of Static Balancing Machines

    Static balancing machines come equipped with features aimed at enhancing their effectiveness:

    Calibration Weights: These machines include standard calibration weights that help in accurately measuring the initial state of balance, facilitating precise adjustments. Easy Operation: Most static balancing machines are designed for user-friendliness, allowing operators to easily perform measurements and adjustments efficiently. Real-Time Feedback: This feature enables quick adjustments based on instant readings, allowing for faster and more accurate balancing procedures. Applications of Static Balancing Machines

    Static balancing machines are pivotal in various industries where rotational components are prevalent. Their applications include:

    Industrial Machinery: Commonly used in the balancing of motors, shafts, fans, and other rotating machinery components. Aerospace: Essential to the aviation industry, ensuring aircraft engines and components maintain optimal performance during operation. Automotive: Used in assembling and maintaining various vehicle parts such as crankshafts, flywheels, and wheels. Manufacturing: Vital in manufacturing operations where rotating tools and machinery play a significant role. Proper balance ensures efficiency and quality output. Conclusion

    Static balancing machines serve as an important tool in numerous fields that depend on the proper functioning of rotating equipment. By ensuring that equipment is well-balanced, these machines help reduce vibration, enhance durability, and improve overall efficiency. Investing in reliable static balancing machines is crucial for industries that prioritize performance and maintenance of their operational assets.
