Cartier The move to the rue de la Paix coincided with a period of extraordinary economic growth and affluence in France and the world. Cartier was also growing and expanding and had started to shift their emphasis from retailing to design and manufacture. Although they produced a small number of pieces in the Art Nouveau style, Cartier paid scant attention to the movement. They made their distinguishing mark in pioneering the use of platinum in creating the delicate and graceful Garland style that came to be associated with the Belle Époque. The discovery of the great diamond deposits in South Africa in the late 1860’s engendered the popularity of extravagant diamond jewelry. The technical advances in the manufacturing of platinum enabled designs of great intricacy, strength and flexibility such as found in the spectacular résille designs of Cartier. (See Edwardian Jewelry: 1901-1915). Cartier marked the beginning of the twentieth century by opening branches in London and New York, where their wealthiest and most dedicated clientele resided. The 1902 coronation of Edward VII occasioned a large number of commissions from England’s leading families. Records indicate that Cartier produced twenty-seven tiaras alone for the coronation and the event was instrumental in convincing the firm to seek a permanent presence in London. Indeed, by 1904 they had achieved their first of fifteen royal warrants being appointed official purveyor to the court of King Edward VII. The London branch came to thrive under the tutelage of Alfred’s youngest son, Jacques Cartier, establishing London based design and manufacturing workshops. Opening a Cartier store in New York was a natural progression as many of America’s wealthiest families and business magnates had been traveling to Paris for some time to purchase their jewels from Cartier. By 1906 Alfred had largely retired and Louis and his brother Pierre operated the Cartier business jointly. One of their first major decisions was to establish a New York presence and workshop in 1909 under the skilled direction of Pierre. Indicative of his business skills, Pierre famously secured Cartier’s present location, an elegant Beaux-Arts mansion at 653 Fifth Avenue, from industrialist Morton F. Plant in 1917. The building changed hands in exchange for $100 and a double strand of natural pearls, admired by Plant’s wife and valued at one million dollars, the asking price for the mansion. While the Fifth Avenue location remains priceless to the firm, when the pearls came up for auction in 1957, they fetched a mere $170,000. (From Lang's with thanks). Edwardian Jewelry This Period was during the King Edward VII, after whom this period of jewelry history is named, reigned over England for only nine years, yet the style of jewelry known as “Edwardian” was created roughly between 1890 and 1920. Edwardian-era rings tend to be larger, opulent pieces, and stacked ring designs were popular. The metal surfaces of the rings were often diamond-encrusted for additional shimmer. Each of these rings is a work of art, showcasing a bygone era of grace, elegance and the royalty the Edwardian era is named for. Guilloché This term is used in fine jewelry or objects de Vertu to enhance the appearance of boxes, frames, brooches, rings or pendants. Guilloché enamel refers to metal pieces that have been given the Guilloché treatment and then covered with a translucent layer of enamel, giving the geometric patterns underneath the enamel a colorful hue. Millegrain This is a jewelry technique which refers to the textural effect of a close-set line of metal beads that are typically used as a border on the edges or bezels of jewelry.

Vintage Aquamarine Diamond Platinum fringe necklace, circa 1950s. The Vintage Aquamarine Diamond Platinum Fringe Necklace, dating back to the 1950s, exemplifies the opulence and intricate craftsmanship characteristic of mid-20th century jewelry design. This period was marked by a resurgence of interest in elaborate adornments that not only showcased gemstones but also reflected the cultural and social dynamics of post-war society. The necklace's use of aquamarine—a stone traditionally associated with tranquility and clarity—paired with diamonds set in platinum, underscores its luxurious nature while simultaneously highlighting the aesthetic preferences of its time. The design features a fringe style, which was particularly popular during this era. This motif allows for movement and fluidity in the piece, creating an eye-catching interplay of light as it catches reflections from both the aquamarine and diamond stones. Each aquamarine is typically cut to enhance its natural brilliance, while the diamonds serve to accentuate their color through contrast. The choice of platinum as a setting material is significant; known for its durability and resistance to tarnish, platinum not only provides a secure mount for these precious stones but also contributes to the overall elegance and longevity of the piece. Moreover, this necklace can be contextualized within broader historical trends in jewelry-making during the 1950s. The post-war boom led to increased consumerism and an appetite for luxury goods among affluent classes. In this sense, pieces like this vintage fringe necklace...
