4. How is Preciosa crystal different from other crystal?
Preciosa Czech Crystal is made with incredibly high quality raw materials including silica sand, sodium, potassium carbonate, minium and other materials which are melted at high temperatures. Preciosa then processes their crystal with the use of their trademarked Hi-Pure Crystal technology which, according to Preciosa, gives their crystal “extraordinary optical and aesthetic characteristics.” Finally, Preciosa’s stones are machine-cut to ensure incredibly clean lines and precise faceting. This gives them an extraordinary brilliance not found in lower-grade crystal.
