About the metals and other materials used in our jewelry
Alpaca silver is often the material of choice for those who craft jewelry by hand. It's malleable and can be bent into shape with pliers alone, while mimicking the sheen and appearance of silver. It's much more affordable than authentic silver jewelry -- a plus when shopping on a budget. High-grade alpaca does not stain and is hypoallergenic, making it ideal for those with silver and metal allergies.
