Art Deco Old Mine Cut Diamond Ring with Trilliant Sapphire Accents

This fabulous engagement ring exudes Art Deco style, characterized by a simultaneously bold and refined design. This ring is a study in geometry, with square and triangular shapes creating the center profile and further triangular cutouts completing the filigree gallery. The center old mine cut cushion dates the diamond to the middle part of the 19th century, 60-80 years before this ring was made. When the jewelers made the ring as we see it in the 1920s, they designed a square setting for the older diamond, framed on either side by triangle settings for the trilliant-cut blue sapphires. True to the period, these sapphires are lab-grown but in beautiful condition and original to the ring. The maker, Belais, a preeminent American jeweler of the 1920s and 1930s and inventor of high-karat white gold, signed this Deco engagement ring. This is evident in the yellowish glow visible on the sides of the ring, which can be removed by request with rhodium plating.
