About the weight:

Different techniques are used depending on the size of each shape to make them surprisingly light, hollow and easy to wear by keeping the weight to a minimum, averaging between the weight of a nickel and a dime.

Earwires:

They are made of sturdy (20 gauge) 14k gold-filled wires. As opposed to a gold-plated wires, gold-filled ensures there is a thick gold layer that stands up to heat, water or wear and will usually maintain its golden shine for a lifetime.
Also available with solid sterling silver earwires. Both the gold-filled and sterling silver wires are nickel-free.
