There are various hallmarks such as silver, 925, 800, and pure silver. The second picture is a ring. The third picture is earrings. The fourth picture has a silver clasp, but it's not included in the total weight. The fifth picture looks like silver and is probably stainless steel, but I'll include it. It's not included in the weight. There are hallmarks on almost all items, but there may be a few without hallmarks due to oversight. Please feel free to ask any questions. ┏○ Pecko (bowing) As of December 29th: I'm calculating based on the current market price of silver 925, which is about 390 yen x 300g (the weight after deducting the stones).
