This lovely jewelry set features a beautiful created opal as the centerpiece, making it a perfect birthstone gift for October birthdays or anyone who loves the magical shimmer of opals. The set includes a halo pendant necklace and matching stud earrings. The opal is lab-created, which means it has the same gorgeous play-of-color as natural opal but at a more affordable price. The pendant measures about 26mm x 10mm (roughly 1 inch by 0.4 inches) and hangs from an 18-20 inch box chain with a 2-inch extender, so you can adjust the length. The earrings are simple studs, about 18mm x 9mm. Both pieces are made with a base of eco-friendly brass, plated in your choice of 18K white gold, rose gold, or yellow gold finishes, and they're nickel-free and hypoallergenic. The earring backs are 925 sterling silver for durability. Total weight is around 5.78 grams, so they're lightweight and comfortable for all-day wear. Whether it's for a birthday, anniversary, graduation, or just a treat-yourself moment, this set offers a touch of elegance without breaking the bank. Comes ready to gift!
