The Astor: An Art Deco Masterpiece

The Hall of Mirrors Effect The centerpiece of this remarkable ring is a striking emerald-cut lab-grown diamond, celebrated for its geometric precision and step-cut facets that create a mesmerizing "hall of mirrors" optical effect. Available in majestic 2.00ct or 3.00ct weights, this ethically cultivated diamond delivers exceptional clarity and sophisticated flashes of light, drawing the eye deep into the stone.
