Hand-cut crystal
Our hand-cut crystal is cut by hand in two stages on an iron and then a sandstone wheel. Each crystal is then polished on a wood wheel with marble dust. These methods go back centuries. If you look closely you will notice faint traces of the wood-wheel attesting to the concentrated labor of the artisan. This is a mark of authenticity. Each piece is a unique and original masterpiece.
30% Full Lead Crystal (-30)
Precision machine cut and polished full lead crystal. This type of crystal has at least 30 per cent lead content which gives it color refraction and beautiful sparkle. This grade is the highest grade available in crystal. Beware of claims such as "100% crystal" by some retailers. Crystal can only have upto 35% lead content.

Full Lead crystal is lead glass that has been machine-cut with facets. Lead oxide added to the molten glass gives lead crystal a much higher index of refraction than normal glass, and consequently much greater "sparkle" by increasing specular reflection and the range of angles of total internal reflection. Ordinary glass has a refractive index of n=1.5, whereas the addition of lead produces a range up to 1.7.[1] This heightened RI also raises the correlating index of dispersion, which measures the degree to which a medium separates light into its component spectra, as in a prism. The presence of lead also makes the glass softer and easier to cut. Crystal can consist of up to 35% lead, at which point it has the most sparkle. The higher lead content also makes it much more difficult to form crystal during manufacturing. Ordering your dining room crystal chandeliers is easy with our shopping cart.
Swarovski Strass Crystal
A perfectly cut crystal uses the same effect as natural phenomena such as the rainbow, by refracting natural light into all the colors of the spectrum. This apparently accidental kaleidoscope of colors can be accurately calculated and exploited to produce stunning effects.
Light makes the perfect "partner"! It unfolds its magic kaleidoscope of color only in combination with perfectly cut crystal of the highest purity. This is why the unrivalled quality of STRASS® crystal is immediately obvious to every observer.
The purer the crystal and the more precise the cut, the more brilliant the effect. This is why only high-quality raw materials are used to make STRASS® crystals. Highly sensitive cutting machines guarantee the absolute precision of every individual facet. A special polishing process ensures that the STRASS® crystals are extremely smooth, which protects them against dirt. Finally each individual STRASS® crystal is inspected with the greatest meticulousness and care by trained hands and unerring eyes. The Swarovski light laboratory is constantly researching into new and unique optical effects and laying the foundations for the development of new cuts, shapes, colors and other innovations.
Original STRASS® crystal products are immediately identifiable because of their laser-engraved STRASS® signature and the intense kaleidoscope of colors they produce. Lights which are decorated exclusively with STRASS® crystals are also labeled with the special STRASS® certificate.
