Thank you for viewing. This is a Van Cleef & Arpels Perlee Signature ring. It's a popular yellow gold. The size is 48, which is equivalent to size 8 in Japan. However, based on my experience, the mirrored inner surface between the Perlee beads has a slight expansion, so it felt like wearing two extremely thin size 8 rings with a space in between. Although it has a wide design, I personally don't think you need to consider sizing up. I purchased it at a Van Cleef & Arpels authorized store in Tokyo. I am reluctantly selling it because it no longer fits. The box, ribbon, and warranty card are all included. Please consider it.
