A California woman has filed a $5 million lawsuit against Jewelry Television, accusing the Knoxville-based home-shopping channel of false advertising, The Associated Press reports.

Marliese Weed claims in the lawsuit filed May 23 in U.S. District Court in San Diego that Jewelry Television sold gemstones described as rare and expensive red or green andesine labradorites, the AP reports. Weed said the items were actually colorless or yellow common feldspar that had been chemically treated.

The lawsuit is seeking class-action status, estimating thousands of customers purchased the questionable gemstones.

In a statement, Jewelry Television acknowledged Monday that it has discovered one of its sources for the gemstone that treated the stone, the AP reports.

The company reportedly said it shared that information with its customers and feels it acted responsibly and says that “the true facts will vindicate us.”
