Enhance your handmade jewelry creations with the deep, rich elegance of our Natural Black Onyx Oval Cabochon Lot. These high-quality, calibrated gemstones are expertly cut with a smooth domed top and flat back, ideal for a variety of jewelry settings and creative projects. Sourced from natural onyx, each stone is polished to a glossy finish, showcasing the luxurious black tone that makes onyx a timeless favorite among designers and collectors. Available in a full range of sizes from 5x7mm to 15x20mm, these Oval cabochons provide flexibility for any design, whether you're crafting delicate stud earrings or bold statement rings and pendants. The flat-back design makes setting simple and secure, perfect for bezel settings, glue-on mountings, or wire wrapping. Our Black Onyx Cabochon Lot is ideal for professional jewelers and hobbyists alike. The stones are hand-selected for their uniform size, deep black color, and high polish.
