Paris Hilton may not be hawking her ridiculous engagement ring anytime soon, but it's not too late to score some bling from another of America's royals. This weekend's International Gem and Jewelry Show offers up a collection of jewelry and a bright red dress worn by her highness Elizabeth Taylor. But Queen Liz's goods are only part of this huge expo showcasing precious gems and minerals, jewelers and craftsmen, estate and costume jewelry and other celebrity exhibits. 11 a.m. to 5 p.m. Reliant Center, One Reliant Park.
