This is a platinum ring with a floral pattern, passed down from my grandmother. It's stamped "Pm" instead of "Pt," which is an older platinum hallmark. She said she bought it over 50 years ago at Takashimaya (the Takashimaya mark is also next to the Pm mark). My grandfather used to be a watchmaker in Ginza, so I believe she bought it then. I can't wear rings due to my job, and the size doesn't fit, so I'm offering it to someone who will cherish it. It's an antique, so it has some minor scratches.
