Striking Emerald-Cut and Round-Cut Diamonds Lead Bid Global International Auctioneers LLC’s Upcoming Sale

Origins of the emerald-cut diamond go back to the table-cut style of the 1500s, when stonecutters used the cutting process for emerald gemstones. The cutters adopted this shape for diamonds, and that’s when the term ‘emerald-cut’ came into being. In the 1920s, emerald-cut diamonds became popular with the onset of the Art Deco movement. The upcoming sale, offered by Bid Global International Auctioneers LLC, features a square emerald-cut GIA-graded diamond. It measures 7.61 carats and features clean lines and symmetry. With its vintage look, the emerald style is valued for its durability and robustness. Another noteworthy emerald-cut piece in the catalog is a diamond measuring 7.03 carats.  

Two round-cut pieces also highlight the sale. One weighs 5.88 carats and the other weighs 9.52 carats. In 1919, Belgian gemologist Marcel Tolkowsky developed a mathematical method for angling facets on diamond to enhance its brilliance and optimize the round cut shape. Two deep brown yellow natural fancy pieces, weighing 2.52 carats and 2.27 carats, lead the listings. Brown diamonds occur in hues ranging from yellow to orange tint.
