Green stone necklace. A collection of items kept by a lady who particularly loves emeralds. She collects many green stones that are close to blue. There seem to be various names, and I don't know them. Chain: Silver 925 stamped. My father often attends social gatherings for work, so he has many accessories, bags, and clothes, but they are all rarely used. There's no doubt it was purchased at Daimaru. Department store purchase. It's beautiful, but I'll try to take it to the department store to be polished if I have time tomorrow.
