Crafted in 10K Gold, this stunning floral belly button ring features six marquise-shape Simulated Diamond Cubic Zirconia (CZ) accents. It measures 24mm in length and 9mm in width. We use high quality Cubic Zirconia Simulated Diamonds in our jewelry. Cubic Zirconia, or CZ, is a stone so optically close to Diamond that most jewelers cannot tell the difference between a CZ and a Diamond with the naked eye. It resembles the same optical characteristics, radiance and beauty as Diamonds. CZ is much less expensive than Diamond, optically flawless, and can be created in a variety of different colors. The biggest difference is that CZ is 70% heavier than Diamond. CZ is extremely durable with a hardness rating of 8.5 compared to 10 for Diamond. This belly button ring comes with a 10K stamp guaranteeing its authenticity. 10K Gold is nickel-free and hypoallergenic making this body jewelry safe and comfortable for people with sensitive skin. The belly button ring arrives in an elegant gift box making it perfect for gifting to your loved ones on any special occasion. Jewelry Care: Over the course of time, body oil and skin products can collect on jewelry and leave a residue which can cause the metal and brilliance of stones to dull. To keep your jewelry looking bright and new, take a soft headed toothbrush with some mild soap and gently brush the front and back of the stones and metal. Rinse thoroughly with tepid water. Steam cleaning works well, but do not steam emeralds or opals as high heat can damage these stones. AVORA fine jewelry is delicate in nature and should be handled carefully as outlined in the care instructions.
