All That Glitters – Rhinestone Jewelry – Part III
Just like any fine crystal, all quality rhinestones are lead crystal. The amount of lead within the rhinestones can range from 20% -30% lead by weight. It is estimated that Swarovski rhinestones contain about 32% lead or lead oxide in them. The lead is used to maximize the way the light refracts through the crystal which gives them an almost diamond-like sparkling quality. Lead crystal is very soft compared to glass and can be damaged by exposure to of even mildly acidic solutions.
We previously talked a little about Swarovski rhinestones, now we’re going to fill you in on Czech rhinestones.
Czech Machine Cut Rhinestones are a very fine lead crystal rhinestone, usually cut with 8 facets and a relatively large table (the flat top of the rhinestone). At distances of more than about 6 feet, these stones flash brighter than do Swarovski. These rhinestones are generally less expensive that Swarovski and because of greater “sparkle factor” from a distance, are often a costumer designer’s favorite. While the crystal is not quite as bright due to slightly lower lead content, it is difficult to tell the difference at distances greater than 6 feet.
Rhinestone jewelry made from machine cut rhinestone crystal is every bit as sparkly and beautiful as jewelry made from Swarovski rhinestone – however, it is usually far less expensive.
