18K Yellow Gold 2.56CTW Diamond Omega Collar Necklace

This estate 18 karat yellow gold omega collar necklace features a sleek bypass design that places a single round diamond at the center of the neckline. The diamond weighs 2.56 carats and is framed by two tapered ends of the collar that gently curve around the stone, creating a sculptural focal point. The smooth omega link construction gives the necklace a fluid yet structured feel that sits cleanly along the collarbone.

The design has a confident simplicity that allows the diamond to command attention while the polished gold collar provides a strong, elegant frame. Its low, graceful curve follows the neckline naturally, making it a striking piece to wear with open necklines or evening attire. The bypass setting adds just enough movement to keep the design feeling modern while still maintaining the classic presence of a diamond collar necklace.

Omega Collar Necklaces

Omega collars are known for their smooth, structured construction created by tightly linked metal segments. Unlike flexible chain necklaces, this style holds its shape, allowing it to rest cleanly along the neckline and maintain a polished appearance.

Because of their structured form, omega collars are often used in designs that feature a central gemstone or focal element. The solid curve of the collar frames the stone and naturally draws attention to the center of the necklace.
