Monumental Ring "Marchesa" Vittorian (19th Century) in 18kt Gold and Silver with No Heat 4.21 ct Natural Ruby Certificato and 4.00 ct Old Mine Diamonds Extraordinary jewelry antique masterpiece: a monumental navette ring (Marchesa model) from the Victorian era, skillfully handcrafted in the second half of the 19th century in yellow gold 18kt and silver. It centers an exceptional and very rare natural ruby from East Africa of 4.21 ct, non-heat treated (No Heat), surrounded by a triumph of Old Mine-cut diamonds totaling approximately 4.00 ct. Supplied with a GUILD GEM Gemological Certificate. Description of the Lot This magnificent ring represents the pinnacle of pomp and opulence of high aristocratic jewelry during the Victorian era. The majestic navette-shaped elongated crown (measuring a full 3.4 cm) is entirely handmade according to the era’s noblest techniques: the back mounting and the shank (which gracefully forks over the shoulders) are crafted in solid 18kt yellow gold, while the sumptuous front plate is in silver finely darkened by time to maximize the contrast and fire of the stones. At the center of the composition shines a monumental natural ruby of 4.21 carats enclosed in a slim yellow gold bezel that enhances its reflections. The gem boasts an incredibly saturated Deep Red color. The complete absence of heat treatment (No Heat) on a stone exceeding the critical 4-carat threshold is an extreme rarity, placing the piece in the category of globally investible assets. To form a superb frame around the central gem is a geometric-floral cascade composed of substantial natural diamonds in Old Mine cut (totaling 4.00 carats). The diamonds, with their tall profile and unique period facets, emit a warm and vivid light, creating a regal and magnetic contrast with the silver’s darkened surface and the ruby’s velvety red.
