Swarvoski Crystals vs Preciosa Crystals

Swarvoski Crystals

Swarovski is the leader in the production of precision-cut crystals that are used in the fashion and jewellery industry as well as in the world of lighting design, architecture and interior.

 Swarovski crystals have become an indispensable material for the creations of international designers. Swarovski crystals are recognised as the highest quality man-made crystals in the world

What are Swarovski crystals made of?

Unlike natural crystal, such as quartz or amethyst mined from the Earth, Swarovski crystals are man-made, created from a combination of natural minerals and pure quartz sand.  

The key ingredient for Swarovski's crisp, clear, and ultra-sparkly crystals was the addition of lead. Originally created with a 32% lead content in order to maximise light refraction or the disco-like rainbow prism effect, that dances within the crystal.

In 2012 Swarvoski launched their Advanced Crystals which are lead-free. 

Advanced Crystal

Swarovski crystals are now considered to be "Lead-Free", as it contains .009% (90ppm) of lead or less. (0% lead is not technologically feasible as there are inherently traces of lead in the environment.)


Advanced optical measurement and high-precision manufacturing deliver premium cuts characterised by unmatched brilliance.
