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 18k rose gold ring features a stunning 3.28ct Oval Cut purple spinel accompanied by a Guild Laboratories certificate stating that the stone is Unheated with Sri Lankan origin. Sourced from the famous mines in Sri Lanka, the spinel was hand cut by our master cutter to bring out the warm and richly saturated purple color, a characteristic that can be attributed to the presence of iron and chromium. The vibrant 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.
