I received this about three years ago, but I'm selling it because the size and style don't suit me. It's 18K. The size is approximately a US size 4. It also has diamonds. Please note that I have discarded the appraisal certificate and box. I will carefully package it for shipping. 【Material and Quality】 This ring is made of high-quality gold (Au 750), combining durability and beauty. 【Design】 With a simple band ring design, it's easy to match with any style and is suitable for everyday wear and special occasions. 【Beauty of the Stones】 The ring is adorned with small diamonds, which emit a modest yet brilliant sparkle. - Material: Gold - Stone Type: Diamond - Hallmark: Au 750 - Design: Simple band ring Thank you for viewing.
