If a warning is placed on a product label or posted or distributed at the workplace, a business, or in rental housing, the business issuing the warning is aware or believes that one or more listed chemicals is present. By law, a warning must be given for listed chemicals unless exposure is low enough to pose no significant risk of cancer or is significantly below levels observed to cause birth defects or other reproductive harm.
For a chemical that causes cancer, the "no significant risk level” is defined as the level of exposure that would result in not more than one excess case of cancer in 100,000 individuals exposed to the chemical over a 70-year lifetime. In other words, a person exposed to the chemical at the “no significant risk level” for 70 years would not have more than a “one in 100,000” chance of developing cancer as a result of that exposure.
In regards SPECIFICALLY to SWAROVSKI® crystals it reads:
• Lead Crystal Glasses, Decanters & Pitchers
Lead crystal is also called crystal, flint glass or lead glass and is a soft, fusible, lustrous, brilliant lead-oxide optical glass with high refraction and low dispersion. An Englishman of the early 1600's added lead oxide to molten glass, thereby increasing its luster, brilliance, and refractive potential. The lead made the glass optically denser (more resistant to light rays passing through it). The rays bent as they passed through the lead glass, creating spectrums of pure color and brilliant reflected light. Acidic juices & wines stored in leaded crystal will become contaminated with lead.
Swarovski® crystal beads and components are leaded crystal.
These products should not be used for children’s jewelry.
Helpful hint: Never store liquids in lead crystal glasses or bottles, drink from lead crystal on a daily basis, (especially if you are pregnant!), or feed an infant or child from a lead crystal baby bottle or cup.
WHAT DOES ALL THIS MEAN?
It means that by California law you should know that Swarovski & Strass crystals have lead content and that lead is unhealthy. Touching Swarovski crystals periodically to clean or replace them is not the same as drinking liquids that has been stored in a leaded crystal decanter. If you feel uncomfortable handling Swarovski crystals, you can use gloves or you may purchase our glass crystal strands with are lead free. Currently, Swarovski is in negotiations with the US EPA regarding their line of leaded crystals.
What this also means is that some companies may try to sell you "Non-leaded or Lead Free" Swarovski crystals that may not be Swarovski at all. As Swarovski only manufacturers lead free Crystals under the Spectra Brand Name(Spectra is only distributed to 4 companies worldwide; those companies can not resale the crystal lighting componants, they must be used in the manufacturing of completed lighting fixtures for resale) than the probablity that you are receiving Lead Free Swarovski is questionable. So be sure to look for the appropriate product classification when purchasing leaded, lead-free or glass chandelier or crystal wedding tree parts.
