Purchased around 2015-2016. Used once or twice. This series is still sold in the HALO series. Hallmarked 18K. Pink gold. 0.07 indicates diamonds. I believe the center stone was a ruby. I have lost the original receipt and guarantee card, so I cannot provide detailed information. Please inquire if you have any questions about points that cannot be determined from the images. It will be shipped in the case shown in the images for packaging. The case is an old one I have at home, so please consider it as packing material. Shipping via Yu-Packet Post Mini.
