Did you know that the key element to differentiating real crystal jewelry from cheaper glass imitations is the lead content.
Typical glass beads don’t contain lead or only minimal traces of it. But when lead is added to the equation and you’ve got crystal. The amount of lead determines the quality of crystal.The more lead, the higher the quality. The inclusion of at least 24% lead oxide in the composition is required by law for crystal to be called full lead crystal. The lead lends brilliance and weight to the product.The higher the lead content, the more light and colors it reflects. The lead also make the crystal softer and more conducive to cutting. That’s why the high quality crystal jewelry enjoys a great brilliance and uniform in shape and size.
