Inspired by the delicate textures, motifs and refined symmetry of the Art Nouveau era, the Claire Pettibone Couture Collection embodies the spirit of true romance. Each piece in the collection is meticulously handcrafted in Los Angeles, using only the finest metals and incredibly rare, precious and ethically-sourced gemstones. The Nightingale ring can be customized with the center stone of your choice, or even designed to showcase a treasured heirloom diamond to continue your family legacy. Nightingale is an exquisitely handcrafted vintage-inspired engagement ring designed exclusively for the Claire Pettibone Couture Collection. The platinum ring features a stunning 2.66cts Rectangular Mixed Cut Cut purple sapphire accompanied by a Guild Laboratories certificate stating that the stone is Unheated with Sri Lankan origin. The incredible, uniquely vibrant stone was sourced directly from Sri Lanka and was hand cut to showcase its magnificent and rare purple color. The beautifully saturated center stone is held by eight prongs in a modified buttercup setting and is flanked on either side by two bezel set Round Brilliant Cut diamonds, totaling exactly 0.12ct in weight and graded G-H color and SI clarity. Nightingale is finished with a delicately hand engraved shank, exhibiting an intricate zigzag pattern on the shoulders. Nightingale is currently a size 6 and can be sized to fit. Please contact our concierge if you are interested in making any customizations to the Nightingale ring.
