Art Deco 1.53 Carat Colombian Emerald and Old Mine Diamond Antique Engagement Ring","description":"\u003cp\u003eAn exceptional antique Art Deco Tiffany \u0026amp; Co. three stone engagement ring centered with a GIA-certified 1.53 carat Colombian emerald, accompanied by an AGL report confirming the emerald displays only minor clarity enhancement (oil), flanked by a pair of old mine cut diamonds. Crafted in platinum during the 1920s, the ring is further accented by French cut diamonds set into the shoulders, a hallmark of the refined geometric elegance that defines the Art Deco period. During the Art Deco era, Tiffany \u0026amp; Co. embraced platinum as the ideal medium for creating light mountings with crisp geometric forms that complemented the period's modern aesthetic. Colombian emeralds have long been regarded as the finest in the world, celebrated for their richly saturated green color and exceptional transparency. The AGL designation of minor oil is highly desirable, indicating only minimal traditional enhancement while preserving the gem's natural beauty. Combined with lively old mine cut diamonds and elegant French cut diamond shoulders, this rare Tiffany \u0026amp; Co. ring embodies the sophistication and precision that have made the house's Art Deco jewels among the most sought-after by collectors.\u003c\/p\u003e\n\u003ch4\u003eDetails\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eItem: 9157\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCenter stone: Certified minor oil treatment 1.53 carat Colombian emerald, with AGL CERT#1155490\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAccent diamonds: Although GIA does not identify historic cutting styles such as Old Mine Cut on grading reports, instead using modern shape and faceting terminology, these diamonds exhibit the characteristic proportions and faceting of authentic antique old mine cuts: Certified natural 1.41 carat old mine diamond with K color and SI1 clarity with GIA report \u003ca href=\"https:\/\/www.gia.edu\/report-check?locale=en_US\u0026amp;reportno=1236796489\" title=\"GIA look up\" rel=\"noopener\" target=\"_blank\"\u003e#1236796489\u003c\/a\u003e and 1.43 carat old mine diamond with K color and SI2 clarity with GIA report \u003ca href=\"https:\/\/www.gia.edu\/report-check?locale=en_US\u0026amp;reportno=1236796489\" title=\"GIA look up\" rel=\"noopener\" target=\"_blank\"\u003e#1232796487 \u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eAccented with French cut diamonds\u003c\/li\u003e\n\u003cli\u003eMeasurements: Center measures 7.85 mm tall and 17.7mm wide, band is 1.7mm wide\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMetal: Platinum\u003c\/li\u003e\n\u003cli\u003eMarkings: Tiffany \u0026amp; Co.\u003c\/li\u003e\n\u003cli\u003eEra: Art Deco, c. 1920\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCurrent ring size: 6.25 - ring can be resized\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eShipping\u003c\/h4\u003e\n\u003cp\u003eWe offer free shipping.
