Marcus & Co Art Deco 2.26 Carat Octogonal Cut Colombian Minor Oil Emerald and Diamond Platinum Vintage Engagement Ring
Circa 1920

Antique Art Deco engagement ring centered with a C Dunaigre certified 2.26 carat octagonal Colombian minor oil emerald and approximately 1.00 carats of diamonds within a platinum setting with geometric designs. Founded in 1892, Marcus & Co. was a well-known American jewelry house, especially during the Art Deco period. The brand was recognized for its craftsmanship and designs, often featuring motifs inspired by various cultures and periods, including the Greek key, a symbol of infinity and eternal flow. This ring, marked "MARCUS" to signify its authenticity, features a beautiful Muzo emerald at its center. Muzo emeralds, sourced from Colombia's Muzo mines, are renowned for their rich, vibrant green color, exceptional clarity, and centuries-old reputation as some of the finest emeralds in the world. Platinum mounts were used to create durable settings that highlighted the geometric style of the Art Deco era.
