Gold filled jewelry is made by heat and pressure bonding a layer (at least 25 micron thickness) of gold to some base metal core. It has all the great characteristics of solid gold jewelry. It does not flake off, tarnish or discolor. Gold filled jewelry is an economical alternative to solid gold. Gold plated is a method of covering another type of metal with a very thin, almost microscopic (usually 0.5-micron thick), film of pure gold by electroplating it. Gold-filled jewelry is much more valuable than gold-plated. As an additional note, 18K gold is more yellow than 14K gold and 10K gold. Note: *** This necklace is quite thin (1.7mm wide only).

We have the same necklace in 3mm and 5mm wide for different customer needs *** Please always refer to the description for the measurement of the product.
