No, crystal and lead crystal are not the same. Lead crystal contains lead oxide, which gives it a higher refractive index and greater sparkle compared to regular crystal. Lead crystal is typically used for high-end glassware and decorative items.
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. Crystal without lead is still crystal, i.e. clear glass, however, it is more commonly perceived as &quotglass". The lead also make the crystal softer and more conducive to cutting. This is why the lead crystal is cut and for the most part, the unleaded crystal is not cut.

One way to tell if a decanter is made of lead crystal is to look for a sparkle and sparkle shine in the glass that is not found in other types of glass. Lead crystal is heavier than regular glass and makes a distinct "ping" sound when tapped. You can also check for a hallmark or label indicating that it is lead crystal.
Swarovski crystal does not contain lead as an intentional ingredient in its composition. However, some Swarovski crystal products may have small traces of lead to enhance the refractive quality of the crystal. These products meet safety regulations for lead content in consumer goods.
