Description from the seller
Monumental Victorian “Marquise” Ring (19th Century) in 18kt Gold and Silver with Certified 4.21 ct “No Heat” Ruby and 4.00 ct Old Mine Diamonds
An extraordinary masterpiece of antique jewelry: a monumental navette-style ring (Marquise model) from the Victorian era, masterfully handcrafted in the second half of the 19th century in 18kt yellow gold and silver. At its center is an exceptional and extremely rare 4.21 ct natural East African ruby, unheated (No Heat), surrounded by a magnificent array of Old Mine-cut antique diamonds totaling approximately 4.00 ct. Accompanied by a GUILD GEM Gemological Certificate
Lot Description
This magnificent ring represents the ultimate expression of the splendor and opulence of high aristocratic Victorian jewelry. The majestic elongated navette-shaped crown (an impressive 3.4 cm long) is entirely handcrafted using the finest techniques of the period: the supporting rear structure and shank (which elegantly splits at the shoulders) are made of solid 18kt yellow gold, while the sumptuous front plate is in silver, beautifully darkened over time to maximize the contrast and brilliance of the stones.
At the center of the composition shines a monumental 4.21-carat natural ruby, set in a delicate yellow gold bezel that warms its reflections. The gem boasts an incredibly saturated and captivating deep red color. The complete absence of heat treatment (No Heat) in a stone that far exceeds the critical 4-carat threshold is an extremely rare phenomenon, placing this jewel among investment-grade assets worldwide.
A geometric-floral cascade of substantial natural Old Mine-cut diamonds (a full 4.00 carats in total) forms a superb frame for the central gem. The diamonds, with their high profiles and distinctive period faceting, radiate a warm, vivid light, creating a regal, magnetic contrast with the darkened silver and the ruby’s velvety red.
