I acquired this rare item for 350,000 yen. Final price reduction, appraised. Guaranteed authentic. It's a rare item with a wonderful sparkle, apparently from Ponte. I was told it has a blue diamond, but I have no way to verify that, so please understand. The hallmarks are PV and 0.2. It's lovely. The cross is not perfectly straight. I asked the previous owner, and they said it was handmade, so it wouldn't have the perfectly straight look of a machine cut. It's a high-quality item. It also has the Ponte PV hallmark. The clasp is weak and keeps opening, so please have it repaired.
