Akoya saltwater pearls with department store specifications are jewelry-grade, such as those from Mikimoto. When selecting, it's recommended to look for this pin and the SILVA hallmark. Silver products: 925 Silver, sv, sterling, or 1000 hallmarks. In the West, silver was once a symbol of wealth. Silver products, handmade, were for the wealthy nobility. Then, they spread to the common people. The shine of silver is considered sacred, and it has a meaning of warding off evil. Because it discolors with poison, silver products are often used for tableware and rings, and there is a custom of giving them to loved ones and passing them down. Sending silver products to a bride is part of that custom. Giving a baby a spoon means they will never be in want of food and will be protected from evil. Rings and necklaces also have that meaning. Religiously speaking, the Holy Grail is made of silver, and it is often used for purification cups, etc. Tiffany, which everyone knows, is also a brand with many silver products. They often become tarnished with age, but they can be restored by polishing with a special cloth. Surprisingly, "Kechikun" (a type of cleaning sponge) also works quite well, so it's recommended.
