◆Engraving: Pt900 0.5 ・Natural large diamonds, 3 pieces, total 0.5ct 　The center diamond is slightly larger. ◆Weight: Approximately 9g ・Measured with a household kitchen scale / Please allow for some error. ◆Maximum width: Approximately 8mm ・This is a one-of-a-kind piece, a custom remodel of a 0.5 carat diamond ring I had during the bubble era, into a channel-set ring for everyday wear. Platinum Pt900 is lavishly used, approximately 9g, to create an embedded design where the diamonds won't snag. Showa retro Wide and voluminous Rounded, half-moon shape ◆Worn only a few times for celebratory occasions back then, but due to the soft platinum material, there are some minor scratches. Only the ring will be sent; there are no accompanying documents such as a certificate of authenticity. I have not had it newly polished because I don't want to reduce the gram weight. It is being sold as is. I cannot recommend this to those who prioritize brand names, but it is a genuine item made by a trusted local shop, so please rest assured. I am not a gem professional, so I cannot answer specialized questions about quality, etc. I will leave the timing of price reductions to my discretion. Returns and cancellations after shipping are not accepted to prevent substitution. Due to the high value of the item, please consider carefully and only purchase if you understand and agree. The ring will be carefully packaged and shipped anonymously via the Takkyubin Compact service of Rakuraku Mercari, which is not a postal delivery service.
