Ansuini 18k Gold Cabochon Ruby and Diamond Ring

This high-jewelry ring by the historic Roman jeweler Ansuini features a prominent oval star ruby cabochon weighing approximately 1.63 carats. The central gemstone displays a rich, purplish-red hue and is securely housed in a smooth bezel setting. Flanking the central stone are two brilliant-cut round diamonds totaling approximately 0.14 carats, also bezel-set to ensure a sleek, low-profile silhouette. The entire piece is crafted from 18k yellow gold with a total weight of 6.376 grams. The shank is notably thick and robust, exhibiting a sophisticated fluted or gadrooned texture along the shoulders that tapers into a solid polished band. This textural element reflects classical Italian goldsmithing techniques. Given the maker's pedigree, the craftsmanship is of superior quality with a heavy, substantial feel. The piece appears to be in excellent contemporary condition with minor surface abrasions consistent with periodic wear. The style is timelessly elegant, suggesting a late 20th-century to early 21st-century production period. Hallmarkings for 750 gold and the Ansuini maker's mark would be expected on the interior of the shank.

I have conducted a visual examination of the Ansuini 18k yellow gold ring featuring a 1.63ct star ruby cabochon. My analysis suggests a piece of superior craftsmanship characteristic of the Roman house of Ansuini. The mounting, weighing a substantial 6.376 grams, shows the hallmarks of high-end Italian goldsmithing, specifically in the precision of the fluted shoulders and the integrated bezel settings. The ruby displays a desirable saturated purplish-red hue; however, without a direct light source test, the strength of the asterism (star effect) remains an estimation. The diamonds, totaling 0.14ct, appear to be of high color and clarity, consistent with the brand's standards. The condition is excellent, showing only minor surface wear. The secondary market for signed Italian jewelry remains strong, with Ansuini's limited production and historical pedigree commanding a premium over generic gold and gemstone pieces. Values for similar signed cabochon rings often range between $4,500 and $6,000 at retail. Please note that this appraisal is based on photographic evidence and descriptions. A definitive verification of authenticity requires physical inspection of the '750' and 'Ansuini' stamps. Furthermore, the ruby's value is highly dependent on whether it is of natural origin or has undergone heat or lead-glass treatment. Professional gemological testing (e.g., GIA or SSEF) is required to confirm the ruby's origin and treatment status, which could significantly affect the valuation upwards if the stone is proven unheated and of Burmese origin.
