This chain-style necklace combines 18 karat yellow gold and platinum for a two-tone effect. It features 36 round brilliant cut diamonds (each 2.3mm, .072 carats) with SI1/SI2 clarity and G color, bringing the total diamond weight to 5.23 carats. The diamonds are bezel set in an alternating pattern along the 18-inch chain, creating a diamonds-by-the-yard style. Natural diamonds are used throughout the piece, each secured in its own metal bezel. The mix of platinum and yellow gold creates an interesting contrast that highlights the diamonds spaced along the chain.
