Every piece is made by hand and requires proper care to lengthen their lifespan. Store them in a cool, dry place away from direct sunlight and humid environments. Our 14k gold-filled metal has a significantly thicker coating of 14k gold when compared to standard gold-plated jewelry (over 5x as much). This means the color and shine will last considerably longer when taken care of with love. All of our silver is .925-grade Sterling Silver.
