Antares — Round and Emerald-Cut Lab-Grown Diamond Riviere Necklace

A riviere that alternates emerald-cut and round brilliant lab-grown diamonds along its full length. The step-cut emeralds bring long, clean flashes of light between the rounds, giving the necklace a more architectural feel than an all-round line. At over 18 carats, it is a true occasion piece.

Round and emerald-cut diamonds are claw-set in a steady alternating pattern around the necklace, finished with a secure lobster clasp. The even rhythm keeps the line graphic and balanced from clasp to centre.

• Total diamonds: 91
• Total carat weight: approximately 18.45ct
