Square emerald cuts epitomize the geometric precision and architectural elegance that defined the Art Deco movement, creating perfect foundations for vintage-inspired luxury pieces. The step-cut faceting produces subtle light patterns that emphasize sophistication over sparkle, appealing to collectors who appreciate understated elegance and historical authenticity. This shape’s clean lines and mathematical proportions work beautifully in period-appropriate settings while offering the durability and quality that modern cutting techniques provide in exclusively-designed jewelry.
